La Reforma: La Reforma (English: The Reform ) or the Liberal Reform was initiated in Mexico following the ousting of centralist president Antonio López de Santa Anna by a group of liberals under the 1854 Plan de Ayutla.  From the liberals' narrow objective to remove a dictator and take power, they expanded their aims to a comprehensive program to remake Mexico governed by liberal principles as embodied by a series of Reform laws and then the Constitution of 1857.  The major goals of this movement were to undermine the power of the Catholic Church in Mexico, separate church and state, reduce the power of the Mexican military, and integrate Mexico's large indigenous population as citizens of Mexico and not a protected class.  Liberals envisioned secular education as a means to create a Mexican citizenry.  The liberals' strategy was to sharply limit the traditional institutional privileges ("fueros") of the Catholic Church and the army.  The law prohibiting the ownership of land by corporations targeted the holdings of the Catholic Church and indigenous communities - confiscating Church land.  Indigenous community lands were held by the community as a whole, not as individual parcels.  Liberals sought to create a class of yeoman farmers that held land individually.  No class of individualistic peasants developed with the Liberal program emerged, but many merchants acquired land (and tenant farmers).  Many existing landowners expanded their holdings at the expense of peasants, and some upwardly mobile ranch owners, often mestizos, acquired land previously held by communities.  Upon the promulgation of the liberal Constitution of 1857, conservatives refused to swear allegiance to it and, instead, formed a conservative government.  The result was a civil war known as the Reform War or Three Years' War, waged between conservatives and liberals for three years, ending with the defeat of the conservatives on the battlefield.  Victorious liberal president Benito Juárez could not implement the envisioned reforms due to a new political threat.  Conservatives had sought another route to regaining power, resulting in their active collaboration with Napoleon III's plans to turn the Mexican Empire into a part into the main American ally of the French empire.  Mexican conservatives offered the crown of Mexico to Hapsburg archduke Maximilian.  The French invasion and republican resistance to the French Intervention in Mexico lasted from 1862-67.  With the defeat of the conservatives and the execution of Maximilian, Juárez again took up his duties as president.  In this period from 1867 to 1876, often called the "Restored Republic" liberals had no credible opposition to their implementation of the laws of the Reform embodied in the 1857 Constitution.

Kentucky–Illinois–Tennessee League: The Kentucky–Illinois–Tennessee League (or "KITTY League") was a Class D minor league baseball circuit that went through six different lives.  The first KITTY League played from 1903 through 1906.  The next one ran from 1910 through 1914.  The third try played a single season (1916).  The circuit was revived in 1922 and lasted three years.  The fifth KITTY League lasted the longest, playing from 1935 through 1955 with a break from 1943 to 1945 due to World War II.  The league was also known briefly as the Kentucky–Indiana–Tennessee League, for during this time the league contained teams such as the Evansville Yankees from Evansville, Indiana.  Unlike most leagues that were dormant for years in between playing, the KITTY was pretty much the same league from 1903 to 1955, through its inactive years.  Clifton C. Gosnell was league president in 1906, after which the league stopped playing, and was president in 1910–1911 when play resumed.  Then Dr. Frank H. Bassett was league president 1912–1914, 1916, 1922–1924, and 1935–1937, through the active times and the inactive.  Hopkinsville, Kentucky was represented for 28 of the 31 active seasons of the KITTY League, while Paducah, Kentucky made it for 23.

World War II: World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier.  It involved the vast majority of the world's countries—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis.  It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries.  In a state of total war, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources.

Tecumseh's War: Tecumseh's War or Tecumseh's Rebellion was a conflict between the United States Army and an American Indian confederacy led by the Shawnee leader Tecumseh in the Indiana Territory.  Although the war is often considered to have climaxed with William Henry Harrison's victory at the Battle of Tippecanoe in 1811, Tecumseh's War essentially continued into the War of 1812, and is frequently considered a part of that larger struggle.  The war lasted for two more years, until the fall of 1813, when Tecumseh, as well as second-in-command Roundhead died fighting Harrison's Army of the Northwest at the Battle of the Thames in Upper Canada, near present-day Chatham, Ontario, and his confederacy disintegrated.  Tecumseh's War is viewed by some academic historians as being the final conflict of a longer term military struggle for control of the Great Lakes region of North America, encompassing a number of wars over several generations, referred to as the Sixty Years' War.

It was one of the longest sieges in history that lasted till even after the end of war.  Fahreddin Pasha was the defender of Medina.  Some celebrated him as ""the Lion of the Desert"" despite the suffering of those who remained in Medina.  The siege lasted two years and seven months.

Bougainville Campaign: The Bougainville Campaign was a series of land and naval battles of the Pacific campaign of World War II between Allied forces and the Empire of Japan.  It was part of Operation Cartwheel, the Allied grand strategy in the South Pacific.  The campaign took place in the Northern Solomons in two phases.  The first phase, in which American troops invaded and held the perimeter around the beachhead at Torokina, lasted from November 1943 through November 1944.  The second phase, in which primarily Australian troops went on the offensive, mopping up pockets of starving, isolated but still-determined Japanese, lasted from November 1944 until August 1945, when the last Japanese on the island surrendered.  Operations during the final phase of the campaign saw the Australian forces advance north towards the Bonis Peninsula and south towards the main Japanese stronghold around Buin, although the war ended before these two enclaves were completely destroyed.
