A lingua franca (originally Italian for "Frankish language" - see etymology below) is a language that is used between persons who do not have the same mother tongue.

The terms working language, bridge language and vehicular language are used in the same sense.

Etymology 
Around the Renaissance era a mixed language of Italian (80%) and many words from Turkish, French, Spanish, Greek and Arabic was used in the eastern region around the Mediterranean Sea It was in use as the language of commerce and diplomacy and was called lingua franca. At that time, in the port cities of the Ottoman empire there lived very many Italian speakers. Franca was the Italian word for Frankish. Its usage in the term lingua franca came from its meaning in Arabic. That word came into use before the Crusades, when Europeans used to be called "Franks" or Faranji in Arabic. The term lingua franca is first recorded in English in 1678.

Examples 
There are many languages in all continents that are used as lingua franca.
In Africa: Afrikaans, Berber, Fanagalo, Fula, Hausa, Krio, Manding, Sango, Swahili,  Wolof

In Asia: Akkadian, Arabic, Aramaic, Azeri, Bengali, Chinese, Hebrew, Hindi-Urdu, Malay-Indonesian, Nepali, Persian, Sanskrit

In Europe: English, French, German, Greek, Italian, Latin, Polish,
Portuguese, Russian, Serbo-Croatian, Spanish, Yiddish

In Pre-Columbian America: Chinook Jargon, Nahuatl, Quechua, Tupi
 
Pidgins and creoles: Guinea-Bissau Creole, Tok Pisin

All continents :  Esperanto as an auxiliary lingua franca

For some of them some explanations may be given.
English 
English is the current lingua franca of international business, science, technology and aviation.  It has replaced French as the lingua franca of diplomacy since World War II. The rise of English in diplomacy began in 1919, after World War I, when the Treaty of Versailles was written in English as well as in French. The use of English profited from the important international role of English-speaking nations (the United States and the Commonwealth of Nations) after World War II, particularly in the establishment and organization of the United Nations. English is one of the six official languages of the United Nations (the other five are French, Arabic, Chinese, Russian and Spanish).
When the United Kingdom became a colonial power, English was the lingua franca of the colonies of the British Empire. In the post-colonial period, some of the newly created nations which had many indigenous languages decided to continue using English as the lingua franca to avoid the political difficulties that had developed if one had decided to use only one of the indigenous languages.

French 
French was the language of diplomacy in Europe from the 13th century, and as a result is still a working language of international institutions and is seen on documents ranging from passports to airmail letters. For many years, until the United Kingdom, Ireland, and Denmark joined in 1973, French and German were the only official working languages of the European Economic Community. French was also the lingua franca of European literature in the 18th century.

German 
German was a lingua franca in large portions of Europe for centuries, mainly the Holy Roman Empire.
Greek and Latin 
During the time of the Roman Empire, the lingua francas were Greek and Latin. During the Middle Ages, the lingua franca was Greek in the parts of Europe, Middle East and Northern Africa where the Byzantine Empire had much influence, and Latin was used in the rest of Europe.  Latin was used as the common language of the Roman Catholic Church.  During the Second Vatican Council, Catholic liturgy changed to local languages, although Latin remains the official language of the Vatican. Latin was used as the language of scholars in Europe until the early 19th century in most subjects.

Sauber F1 Team is a Swiss Formula One team. It was founded in the 1970s by Peter Sauber. The team ran its first Formula One in .

Sauber was an independent team, it did not have the backing of a automobile manufacuer such as Ferrari. Having not won a single Grand Prix race, the team was sold to BMW in 2005. The team competed as BMW Sauber from 2006 to 2009, and won one race. At the end of the 2009 season, BMW deceided to leave Formula One.

The race team's future was uncertain for several months. BMW sold the team back to Peter Sauber which allowed the team to race in  entry. Due to issues with the Formula One contract, the team name will remain BMW Sauber for the 2010 season.

Since the 1970s, Peter Sauber built sports cars. After using turbocharged Mercedes V8 engines in the 1980s, his team became the official factory team of Mercedes-Benz, reviving the Silver Arrow legend. They won the 24 hours of Le Mans and the World Sportscar Championship in 1989 and 1990, competing against Jaguar and Porsche.

Formula One

The Mercedes era (1993–1994) 
Mercedes-Benz had planed to enter Formula One with Sauber. They could not work out all the details, so Mercedes withdrew their formal support. Mercedes continued to fund Sauber's Formula One project unofficially. The Sauber team was powered by V10 Ilmor engines in a chassis named the C12. This continued the Sauber's naming policy from the sports car days. The 'C' was a reference to Peter Sauber's wife, Christine. The cars were driven by JJ Lehto and Karl Wendlinger.
The Sauber racing debut took place in the first race of the  season in South Africa. The car finished in fifth place, earning two points under the scoring system at the time. Over the remainder of the season the team rarely saw the finish of a race due to unreliability and racing accidents. When the team did finish a race, they were often in the top ten. Sauber ended the season with twelve points, seventh out of the thirteen original entries.

The team competed in the  season as Sauber Mercedes, now officially Mercedes' factory team. Their new car was the Sauber C13 and the Ilmor engine was re-badged (given a new name) as the Mercedes 3.5 V10. Former Sauber sports car driver Heinz Harald Frentzen was Karl Wendlinger's new teammate.
Early performance was disappointingly, delivering similar results as the previous year. They only scoring a few points in the opening rounds. Things got worse after the tragic deaths of Ayrton Senna and Roland Ratzenberger at the San Marino Grand Prix. Wendlinger was seriously injured in a crash during practice for the Monaco Grand Prix. He suffered serious head injuries and was unable to race for the of the season. Wendlinger was replaced by Andrea de Cesaris. After Lehto had been released by Benetton, he drove for Sauber the last two races of the season.

Sauber finished the season with twelve points and eighth out of the fourteen original teams entered. Mercedes were unhappy with the progress of Sauber and left the team at the end of the year.

The Ford era (1995–1996)
For , Sauber start the beginning of a ten-year sponsorship deal with energy drink giant Red Bull. Dietrich Mateschitz had purchased a majority share in the team. Fritz Kaiser joined the team as the commercial director. The Sauber C14 used a factory supply of Ford-Cosworth. The 1995 season saw the return of Karl Wendlinger and Heinz Harald Frentzen as the drivers. Wendlinger's accident in 1994 seemed to have reduced his driving potential and he was replaced rookie Jean-Christophe Boullion.

The team finished on a record 18 points despite the under-performing Ford engine. They also climbed back up to seventh in the constructor's championship.

In 1995, Petronas become Sauber's presenting sponsor. They renewed their association in 2007, by which time the team had changed ownership.
saw Sauber's worst Formula One season in terms of points. They had a promising driver lineup with Heinz Harald Frentzen and Johnny Herbert, a revised C15 car and a new V10 engine from Ford. They  held seventh spot on a shrinking list of constructors and only scored 11 points. For the next season they announced a customer deal to receive Ferrari V10 engines. They also were working with new sponsors Petronas to build their own engines. Unfortunately, due to a major economic crash in Asia, the engines were never completed.

The Ferrari era (1997–2005)
Sauber used Ferrari designed engines from 1997 to 2005. They were built by Sauber Petronas Engineering, a company founded for purpose of building these engines. The engines were nearly identical to the ones used by Ferrari. Sauber Petronas Engineering also built the gearboxes  used by Sauber. Sauber licensed nearly every part they could from Ferrari. Sauber even had several Ferrari engineers on staff. Suspicious similarities between Ferrari and Sauber chassis were pointed out, but no formal accusations were ever made. The FIA rules require each team to design their own chassis.

In  Sauber brought a virtually unknown and very inexperienced Kimi Räikkönen into Formula One. There were protests by a few drivers and members of the FIA, including Max Mosley. They believed Räikkönen would pose a danger to other drivers. His good performance that year proved the Sauber decision right. Räikkönen would later go on to win the  Drivers Championship with Ferrari.
In its later years, Sauber's ties with Ferrari became weaker. They sided with the other teams over planned rule changes. Then they decided to switch to Michelin tyres, while Ferrari continued to use Bridgestones. Sauber's final grand prix came in China. Sauber departed F1 with their best results; six third places and two front row starts.

Among the notable Sauber drivers were Jean Alesi,  Formula One championship runner-up Felipe Massa, Johnny Herbert and  World Champion Jacques Villeneuve. Two former Sauber drivers, Nick Heidfeld and Jacques Villeneuve, drove for the new BMW Sauber team in 2006. BMW ownership of Sauber started on January 1, 2006.

The BMW era (BMW Sauber, 2006–2009)
At the end of the 2005 season the team was bought by BMW and was renamed BMW Sauber. Peter Sauber retaining a 20% stake in the team. BMW sold its share of BMW Sauber back to Peter Sauber after the end of the 2009 season. Because of their contract with Formula One, the team still formally uses the name 'BMW Sauber' in competitions for .

2006
For the  season the team signed Nick Heidfeld from Williams to be their lead driver, and retained Jacques Villeneuve as the second driver. Polish Robert Kubica was signed as the team's third or test driver. The team continued to use Sauber's facilities, mostly for chassis construction and wind tunnel testing. BMW's headquarters in Munich was responsible for building the new P86 V8 engine.
Former Sauber title sponsor Petronas renewed their contract with the new team, as a simple team sponsor, as did Credit Suisse. BMW Sauber announced a technical partnership with Intel and the Germany company O2, saying that it will lead to technological improvements on BMW road cars. The new livery (paint scheme), unveiled in Valencia on 17 January 2006, was the traditional BMW blue and white with a hint of red.

At the Hungarian Grand Prix, Heidfeld scored the team's first podium. Kubica filled in for Villeneuve. Villeneuve could not drive due to complications following his accident at the German Grand Prix. Kubica finished seventh, but was disqualified for having too light a car. Kubica would drive for the rest of the season, bringing an to Villeneuve's F1 career.

The team's finished the season fifth place in the constructor's championship with 36 points.

2007
2007

For the  season Kubica and Heidfeld were again the teams' drivers. Sebastian Vettel would be the third or test driver. Timo Glock was signed as the team's second test driver.

The performance of the BMW Sauber's F1.08 firmly placed them as the best team behind the two championship leading teams of Ferrari and McLaren.

The Canadian Grand Prix brought the teams best finish to date, with Nick Heidfeld finishing in 2nd place, but Robert Kubica had a huge crash that resulted in a sprained ankle and concussion.

Sebastian Vettel took his place in the United States Grand Prix and finishing in 8th place. He became the youngest driver to score a Formula One World Championship point. After the European Grand Prix, Scuderia Toro Rosso announced that Vettel would take the second driver seat from Scott Speed.

2008

On August 21, 2007, BMW confirmed its driver line-up of Nick Heidfeld and Robert Kubica for the  season. Their 2008 car, the BMW Sauber F1.08 was officially launched in Munich on January 14, 2008.
In Bahrain, Kubica scored his and the team's first ever pole position, beating Felipe Massa by just under three hundredths of a second. The team went on to finish 3rd and 4th in the race, equaling their highest round of points scored. For the first time, the team was in first place in the constructors' championship.

BMW Sauber's first race victory came in the Canadian Grand Prix. BMS Sauber scored a one-two finish with Robert Kubica's first race win and Nick Heidfeld taking second place. This was the first Formula One victory for a BMW engine since the Williams-BMW won the  Brazilian Grand Prix.
After the team's breakthrough win, the team stopped improving the current car. They started work on the new car for  because of the new regulations for the next season. This was reflected in the team's performance for the remainder of the 2008 season. Kubica was leading the drivers championship after the Canadian Grand Prix. The lack of development was shown with a drop in performance through the second half of the season. BMW was outpaced by Renault, Toyota and Toro Rosso

2009

In October 2008 the team confirmed that they would stay with Robert Kubica and Nick Heidfeld as their drivers for the  Season.
On July 28, the company announced the team's withdrawal from Formula One at the end of 2009. BMW Chairman Dr. Norbert Reithofer described the decision as a strategic one. On 15 September 2009 BMW Sauber announced they had a buyer for the team, Qadbak Investments Limited. Qadbak turned to be a shell company (a company without any real assets or operations), and the deal fell apart.

Lotus Racing was given the 13th and final slot in the  Season.

Return to Sauber ownership and Ferrari engines (2010) 

On November 27, 2009 Peter Sauber announced he would purchase the team back from BMW. He would only agree to the purchase if the team receiving a FIA entry for the  season.
On December 3, 2009, the FIA confirmed that Sauber had been granted the entry position left by Toyota's departure from Formula one. The new Sauber team would be using Ferrari engines, and the team's chassis for the 2010 season would be designated Sauber C29. Peter Sauber said that he has not applied to change the name of the team, so they remain for now as BMW Sauber F1 Team despite using no BMW components.

Kamui Kobayashi was signed as a driver for the 2010 season on the December 17, 2009. Pedro de la Rosa was signed as Sauber's second driver on January 19, 2010. Esteban Gutiérrez has joined the team as an observer for some race weekends. He has been placed on the same training program as the race drivers de la Rosa and Kobayashi.

The team struggled in the early rounds of the season, and did not score any points from the first three races. Peter Sauber admitted at this point that his decision to rescue the team had been emotionally-driven, but insisted that it was a correct decision.
The team ran without a primary sponsor for the first four races of the 2010 season. For the Spanish and European Grand Prix, they carried the logo of the Spanish arm of the Burger King fast food franchise.

In Turkey, Kobayashi qualified in the top ten for the race, then finished 10th, collecting the team's first point in 2010.

2011
2011 

For the  season, Sauber kept driver Kamui Kobayashi, and added rookie driver Sergio Pérez. Kobayashi qualified in 9th place, and Pérez in 13th. Pérez received praise for making his tyres last better than any other driver. He needed only one pit stop, when all other drivers needed at least two. They both finished the race in the points. Pérez finished in 7th place, and Kobayashi in 8th. The two Sauber cars were disqualified after the race. The team had made a mistake with the rear wing, and it was not legal.

Pérez suffered a serious crash in the Monaco race. He had intentions of being in the next race, at Canada, and ran in the Friday practice. However, Pérez fell ill (sick) and was replaced by Pedro de la Rosa.

Lawrence is a city in Douglas County in the state of Kansas in the United States. It is in the northeastern part of the state, near Kansas City. It is the county seat of Douglas County. As of the 2020 census, the population of the city was 94,934. This makes it the sixth-biggest city in Kansas. The University of Kansas and Haskell Indian Nations University are in Lawrence.

The New England Emigrant Aid Company (NEEAC) created Lawrence in 1854. It is named after Amos Adams Lawrence, who gave financial support to the city. During Bleeding Kansas, Lawrence was where the Wakarusa War (1855) and the Sack of Lawrence (1856) happened. Lawrence is also the site of the Lawrence Massacre (1863) which happened during the American Civil War (1861–1865).
Lawrence started as an important place for free-state politics. After that, Lawrence's economy grew to be in many industries. These industries include agriculture, manufacturing, and education. Lawrence is called a "college town" because the University of Kansas is an important part of the city. There are many places in town where students like to go.

History

Early history 
Before the creation of the Kansas Territory, the area was part of the Shawnee Reservation. The Shawnee reservation was created in 1830. Most of eastern Kansas was in the reservation. In 1854, it became part of the Kansas Territory. The Oregon Trail went through the area. People on the Oregon Trail used a hill called "Hogback Ridge" to help guide them. Today, Hogback Ridge is called "Mount Oread."
Two newspapers were started in 1854. They were the Kansas Pioneer and the Herald of Freedom. The writers of the newspapers wrote about their belief that slavery was wrong. The Plymouth Congregational Church was built in September 1854; it was the first church in Kansas. In January 1855, Lawrence's first post office was built. The first postmaster was E. D. Ladd. On January 10, 1855, Lawrence's first free school was built. The teacher was Edward Fitch.

"Bleeding Kansas"
"Bleeding Kansas" 

At the start of 1855, the free-staters and the pro-slavery people around Lawrence started fighting for political power. At the Kansas elections on March 30, 1855, about 700-1,000 pro-slavery people from Missouri voted at the election. They came in more than 100 wagons. They had guns, rifles, pistols, and Bowie knives. They also brought two pieces of artillery. No one argued with them because there were a lot of them. They went back to Missouri the next day. Before the election, the government did a census which showed that 8,601 people lived in Kansas. Of those 2,905 were voters; Lawrence had 369 voters. There were a total of 2,905 voters in the territory, but there were 6,307 votes counted. 1,034 votes were cast in Lawrence, but 802 were from people who did not live in Kansas. Only 232 of the votes were real. At the election, a man named Silas Bond was shot at, and he ran away. He was shot at because he was "an obnoxious free-state man."
On August 27, 1855, the pro-slavery people were happy when the Governor Daniel Woodson chose a pro-slavery man, Samuel J. Jones, to be the county sheriff. In October 1855, the anti-slavery man John Brown came to Kansas. He brought many guns to give to other anti-slavery people.

In June 1855, the people of Lawrence had a meeting and decided to resist any laws the Kansas legislature passed. They believed the legislature was elected by armed Missouri people, not Kansas people. Amos Lawrence and others sent crates full of rifles. They wrote on the crates that the things inside were books because "the border ruffians had no use for books," so they did not take the rifles when they came to Lawrence. Horace Greeley helped send a howitzer to Lawrence.
On November 21, 1855, the pro-slavery man Franklin N. Coleman shot anti-slavery man Charles Dow in the head. This killed him. This happened after many angry arguments between them about land claims. When Sheriff Samuel Jones investigated the crime, Franklin Coleman said he shot Charles Dow in self-defense. Jones believed Coleman because they both were pro-slavery men. Jones decided to arrest Jacob Branson, a friend of Charles Dow and an anti-slavery man, for disturbing the peace. A group of anti-slavery people saved Branson.

Sacking of Lawrence
In spring 1856, pro-slavery people wanted to make the free-staters weak. The pro-slavery people said that the Herald of Freedom newspaper, the Kansas Free State newspaper, and the Eldridge Hotel were very bad. On April 23, 1856, Samuel Jones came to Lawrence. He tried to arrest some anti-slavery people who had created their own anti-slavery government. A sniper shot Samuel Jones, but he did not die. The people of Lawrence made Jones leave. On May 11, Federal Marshall (like a police officer but for the entire country) Israel B. Donaldson said that people interfered with Samuel Jones which was not legal. A Kansas grand jury agreed. They said that Lawrence built the Free State Hotel (the Eldridge Hotel) for military purposes. Donaldson, Jones, and others recruited an army of 800 men to enforce the law. However, they also wanted to stop the anti-slavery men in Lawrence.
On May 21, Donaldson and Jones took their army to Lawrence. They arrested more anti-slavery people. The people of Lawrence hoped that Donaldson and Jones would leave after the arrests, but this did not happen. Jones and his men started sacking Lawrence. They took over Charles Robinson's house and used it as a headquarters. They attacked free-state newspapers offices. They struck the printing presses, and they threw the sort into the Kansas River. They shot the Free State Hotel (the Eldridge Hotel) using a cannon and burned it down. They took $30,000 worth of things. After burning Charles Robinson's house, the army left. The day of destruction was called the "Sacking of Lawrence." Surprisingly, only one person died; a man died when he was hit by falling masonry. In late September 1856, another sack seemed like it was about to happen when 2,700 pro-slavery men came to Lawrence. Anti-slavery men defended the city. Governor John W. Geary saw what was happening
. He asked for federal reinforcements to defend the city. No violence happened.
In 1855 and 1857, Lawrence got a charter (a document that officially creates a town) from the pro-slavery Kansas government. The people of Lawrence resisted the Kansas government because they believed they were too pro-slavery. They did not accept it because it would force Lawrence to follow pro-slavery laws. In July 1857, the people of Lawrence tried to get an "official" (only the people of Lawrence saw it as official) charter from the extralegal (having no real authority) anti-slavery government. If they could not get one, Lawrence would simply make one themselves. Governor Robert J. Walker believed this was a revolt. On July 15, 1857, he sent an army to Lawrence and declared martial law. The army stayed close to Lawrence until October 1857. They stayed until October because there were elections. They wanted to make sure that there would be no violence at the elections. Anti-slavery people won the elections. The Kansas government became controlled by anti-slavery people
. In early 1858, Samuel Jones quit his job, and he left Kansas. On January 16, 1858, Lawrence became the county seat of Douglas County. In February 1858, the Kansas government approved an anti-slavery charter for Lawrence. James Blood became the first mayor of Lawrence. The anti-slavery Kansas government met in Lawrence many times. In practice, Lawrence became the capital of Kansas from 1858 until 1861.
American Civil War and Kansas becoming a state 

On October 4, 1859, the people of Kansas voted to approve the Wyandotte Constitution. There were 10,421 "yes" votes and 5,530 "no" votes. The United States Congress approved the Wyandotte Constitution. Kansas became a free state on January 29, 1861. Pro-slavery people in Kansas knew they had lost. Kansas becoming a free state ended Bleeding Kansas. However, the American Civil War began around the same time.
During the war, many Jayhawkers stayed in Lawrence. These Jayhawkers went to Missouri. They stole items and burned farms there. Many people in the Confederacy believed that the stolen items were in Lawrence. On August 21, 1863, a pro-slavery man named William Quantrill rode into Lawrence with some men. They destroyed much of the town. They killed every adult man they saw. More than 150 men and boys died. There was 2,000,000 dollars worth of property destroyed. The Plymouth Congregational Church was not destroyed, but many of its people died. This attack is known as the Lawrence massacre.

After Quantrill's Raid, the people and Union soldiers rebuilt the city. It was not easy because the winter was very cold. They continued rebuilding until they finished in 1864. While they were rebuilding, the people of Lawrence were afraid of another attack. The military built some camps in Lawrence to guard the city, but no more attacks happened. After the Civil War, the camps were closed and removed.
After the Civil War 

There was a plan to build a university in Kansas in 1855, but it did not happen until Kansas became a state in 1861. The Kansas government needed to decide where to build the university. Their choices were Manhattan, Emporia, or Lawrence. On January 13, 1863, Kansas State University was built in Manhattan. However, the Kansas government decided to build another one. The only cities left where a university could be built were Emporia and Lawrence. Amos A. Lawrence gave $10,000 and more than 40 acres (160,000 m2) of land for a university in Lawrence. The Kansas government liked that, so the government chose Lawrence. The University of Kansas opened in 1866.

In 1864, Lawrence got its first railroad. It connected Lawrence to Kansas City. The first train to go to Lawrence went on November 28, 1864. The first train to cross the Kansas River crossed it in Lawrence on November 1, 1867.
In the early 1870s, Lawrence needed more electricity. The city asked Orlando Darling to build a dam on the Kansas River. Darling became angry because it took a long time to build a dam, so he stopped. The Lawrence Land & Water Company finished building the dam in 1873. The dam made Lawrence special because few cities had a dam. The dam closed in 1968, but the city reopened it in 1977. They wanted to build a new city hall next to the dam. Today, the dam helps prevent flooding.

In 1863, the first windmill in Kansas was built in Lawrence. It burned during Quantrill's Raid. In 1864, people rebuilt it. It cost them $9,700. People used it until July 1895. On April 30, 1905, the windmill burned, and it was not rebuilt.
In 1884, a school for Native Americans was built in Lawrence. It was named the United States Industrial Training School. Boys learned farming, blacksmithing, and more. Girls learned cooking and homemaking. In 1887, the name changed to the Haskell Institute. It was named after Dudley Haskell, a state legislator who helped make sure the school was built in Lawrence. In 1993, it was renamed the Haskell Indian Nations University.

20th century 

In 1888, Jabez B. Watkins opened the Watkins National Bank at 11th Street and Massachusetts Street. It closed in 1929. The building was given to the city to become the city hall. In 1970, Lawrence built a new city hall, so the building became a museum. It was called the Watkins Community Museum, and it opened in 1975.
In 1903, the Kansas River flooded, which did a lot of damage. The water was  high. The damage in North Lawrence was very bad. Lawrence was hit by other floods in 1951, when the water was 30 feet high. It was hit again in 1993. However, the damage was not very bad because of the reservoir and a levee.

In 1903, President Theodore Roosevelt came to Lawrence. He gave a short speech, and he dedicated a fountain at 9th & New Hampshire Street. In 1910, Roosevelt came to Lawrence again after visiting Osawatomie.
In 1871, the Lawrence Street Railway Company was created. It made it easy for people to go to hotels and businesses on Massachusetts Street. They had the first streetcar in Lawrence. Horses and mules pulled the streetcar. They could be used only on Massachusetts Street. After the 1903 flood, the Kansas River Bridge had to be rebuilt. It was not safe for streetcars to go on the bridge. The Lawrence Street Railway Company closed in 1903. In 1902, C. L. Rutter tried to start a bus system. He failed. In 1907, he tried again. In 1909, a new streetcar system was built which caused Rutter's buses to close. The streetcar system stayed until 1935. In 1909, the streetcar company made a roller coaster. It was called "Casey's Coaster." Some people called it "Daisy's Dozer." It was made out of wood. It stayed until the 1920s.

In 1921, the Lawrence Memorial Hospital opened with 50 beds. By 1980, it had 200 beds. It has won many awards for good quality care and service.
In 1929, Lawrence had its 75th birthday. To celebrate, a big rock was placed. It is called "Founder's Rock" to remember the early settlers who came to Lawrence from the New England Emigrant Aid Company. On October 14, 1929, they opened the Lawrence Municipal Airport to the public.

In 1943, during World War II, the United States government brought prisoners of war to Lawrence. They were mostly German and Italian people. The government brought them because farmers needed more workers. They were forced to live in camps which were like prisons. Lawrence's camp was near 11th Street and Haskell Avenue. The camp closed in 1945.

In 1983, a famous movie, The Day After, was filmed in Lawrence. The movie is about a fictional nuclear war between the United States and the Soviet Union.

In 1989, the Lawrence Free State Brewing Company opened on Massachusetts Street. It was the first brewery in Kansas in over 100 years. The brewery is also a restaurant.
In 2007, U.S. News & World Report said Lawrence was one of the best places to retire. In 2011, Parents & Colleges said Lawrence was one of the 10 best college towns in the United States.
