## History
### Illinois Industrial University (1867–1885)

The University of Illinois, originally named "Illinois Industrial University", was one of the 37 universities created under the first Morrill Land-Grant Act, which provided public land for the creation of agricultural and industrial colleges and universities across the United States. Among several cities, Urbana was selected in 1867 as the site for the new school. From the beginning, President John Milton Gregory's desire to establish an institution firmly grounded in the liberal arts tradition was at odds with many state residents and lawmakers who wanted the university to offer classes based solely around "industrial education". The university opened for classes on March 2, 1868, and had two faculty members and 77 students.
The library, which opened with the school in 1868, started with 1,039 volumes. Subsequently, President Edmund J. James, in a speech to the board of trustees in 1912, proposed to create a research library. It is now one of the world's largest public academic collections. In 1870, the Mumford House was constructed as a model farmhouse for the school's experimental farm. The Mumford House remains the oldest structure on campus. The original University Hall (1871) was the fourth building built; it stood where the Illini Union stands today.
The University of Illinois' Undergraduate Library (UGL) was constructed underground to preserve open space on campus and to prevent casting shadows on the adjacent Morrow Plots, the oldest continually used experimental agricultural fields in the United States. This unique design inspired The Other Guys, a student a cappella group, to create the "Morrow Plots Song," humorously explaining that the library was built underground "'Cause you can't throw shade on the corn". The song has become a beloved piece among students and alumni, celebrating the university's history and traditions.

### University of Illinois (1885–1977)

In 1885, the Illinois Industrial University officially changed its name to the "University of Illinois", reflecting its agricultural, mechanical, and liberal arts curriculum. According to educational historian Roger L. Geiger, Illinois and a few other public and private universities set the standard for what the research university in the United States would become. During his presidency, Edmund J. James (1904–1920) set the policy of building a massive research library. He also laid the foundation for the large Chinese international student population on campus. James established ties with China through the Chinese Minister to the United States Wu Ting-Fang. Class rivalries and Bob Zuppke's winning football teams contributed to campus morale.
Alma Mater, a prominent statue on campus created by alumnus Lorado Taft, was unveiled on June 11, 1929. It was funded from donations by the Alumni Fund and the classes of 1923–1929.
The Great Depression in the United States slowed construction and expansion on the campus. The university replaced the original university hall with Gregory Hall and the Illini Union. After World War II, the university experienced rapid growth. The enrollment doubled and the academic standing improved. This period was also marked by large growth in the Graduate College and increased federal support of scientific and technological research. During the 1950s and 1960s the university experienced the turmoil common on many American campuses. Among these were the water fights of the 1950s and 1960s.

### University of Illinois Urbana-Champaign (1977–present)

By 1967, the University of Illinois system consisted of a main campus in Champaign-Urbana and two Chicago campuses, Chicago Circle (UICC) and Medical Center (UIMC), and people began using "Urbana-Champaign" or the reverse to refer to the main campus specifically. The university name officially changed to the University of Illinois at Urbana-Champaign by 1977 (although the word "at" was later dropped for marketing purposes by all U of I System campuses by 2021). While this was a reversal of the commonly used designation for the metropolitan area (Champaign-Urbana), a majority of the campus is located in Urbana. The name change established a separate identity for the main campus within the University of Illinois System, which today includes separate institutions at the University of Illinois Chicago (formed by the merger of UICC and UIMC) and University of Illinois Springfield.
In 1998, the Hallene Gateway Plaza was dedicated. The Plaza features the original sandstone portal of University Hall, which was originally the fourth building on campus. In recent years, state support has declined from 4.5% of the state's tax appropriations in 1980 to 2.28% in 2011, a nearly 50% decline. As a result, the university's budget has shifted away from relying on state support with nearly 84% of the budget coming from other sources in 2012.
On March 12, 2015, the Board of Trustees approved the creation of a medical school, the first college created at Urbana-Champaign in 60 years. The Carle Illinois College of Medicine began classes in 2018.

### Philanthropy

Over the last twenty years state funding for the university has fallen. Private philanthropy increasingly supplements revenue from tuition and state funding, providing about 19% of the annual budget in 2012. Notable among significant donors, alumnus entrepreneur Thomas M. Siebel has committed nearly $150 million to the university, including $36 million to build the Thomas M. Siebel Center for Computer Science, $25 million to build the Siebel Center for Design, and $50 million to support the renamed Department of Computer Science to become Siebel School of Computing and Data Science. Furthermore, the Grainger Foundation (founded by alumnus W. W. Grainger) has contributed more than $300 million to the university over the last half-century, including donations for the construction of the Grainger Engineering Library. Larry Gies and his wife Beth donated $150 million in 2017 to the shortly thereafter renamed Gies College of Business.

## Campus

The main research and academic facilities are divided almost evenly between the twin cities of Urbana and Champaign, which form part of the Champaign–Urbana metropolitan area. Some parts are in Urbana Township.
Four main quads compose the center of the university and are arranged from north to south. The Beckman Quadrangle and the John Bardeen Quadrangle occupy the center of the Engineering Campus. Boneyard Creek flows through the John Bardeen Quadrangle, parallel to Green Street. The Beckman Quadrangle, named after Arnold Orville Beckman, is primarily composed of research units and laboratories, and features a large solar calendar consisting of an obelisk and several copper fountains. The Main Quadrangle and South Quadrangle follow immediately after the John Bardeen Quad. The former makes up a large part of the Liberal Arts and Sciences portion of the campus, while the latter comprises many of the buildings of the College of Agriculture, Consumer, and Environmental Sciences (ACES) spread across the campus map.
Additionally, the research fields of the College of ACES stretch south from Urbana and Champaign into Savoy and Champaign County. The university also maintains formal gardens and a conference center in nearby Monticello at Allerton Park.
The campus is known for its landscape and architecture, as well as distinctive landmarks. It was identified as one of 50 college or university "works of art" by T.A. Gaines in his book The Campus as a Work of Art. The campus also has a number of buildings and sites on the U.S. National Register of Historic Places including Harker Hall, the Astronomical Observatory, Louise Freer Hall, the Main Library, the Experimental Dairy Farm Historic District, and the Morrow Plots. University of Illinois Willard Airport is one of the few airports owned by an educational institution.

### Sustainability

In 2008, the University of Illinois Urbana-Champaign became a signatory of the American College and University Presidents' Climate Commitment, binding the campus to the goal of carbon neutrality as soon as possible. In 2010, the first Illinois Climate Action Plan (iCAP) was written to chart a path to this goal. The iCAP is a strategic framework for meeting the university's Climate Leadership Commitments to be carbon-neutral by 2050 or sooner and build resilience with its local community. Since then, the iCAP has been rewritten every five years to track the university's progress.
In December 2013, the University of Illinois launched the Institute for Sustainability, Energy, and Environment (iSEE) on the Urbana-Champaign campus. The institute, under the Vice Chancellor for Research and Innovation, leads an interdisciplinary approach to researching solutions for the world's most pressing sustainability, energy, and environmental needs. In addition, iSEE has engaged students, faculty, staff, and campus leadership in the iCAP process — especially in the areas of zero waste and conservation of energy, food, water, land, and natural resources — as well as sustainability outreach and immersive educational programs.
In 2022, new solar and geothermal energy projects, a reduction in water use, and wide-ranging sustainability research helped the University of Illinois Urbana-Champaign earn its fifth consecutive gold certification in the Sustainability Tracking, Assessment & Rating System (STARS). Illinois has consistently achieved gold certification since it began reporting data through STARS in 2013, and the 2022 score was one of its highest to date.
Currently, the campus features 27 LEED-certified buildings.

### Academic divisions

The university offers more than 150 undergraduate and 100 graduate and professional programs in over 15 academic units, among several online specializations such as Digital Marketing and an online MBA program launched in January 2016. In 2015, the university announced its expansion to include an engineering-based medical program, which would be the first new college created in Urbana-Champaign in 60 years. The university also offers undergraduate students the opportunity for graduation honors. University Honors is an academic distinction awarded to the highest achieving students. To earn the distinction, students must have a cumulative grade point average of a 3.5/4.0 within the academic year of their graduation and rank within the top 3% of their graduating class. Their names are inscribed on a Bronze Tablet that hangs in the Main Library.

### Online learning

In addition to the university's Illinois Online platform, in 2015 the university entered into a partnership with the Silicon Valley educational technology company Coursera to offer a series of master's degrees, certifications, and specialization courses, currently including more than 70 joint learning classes. In August 2015, the Master of Business Administration program was launched through the platform. On March 31, 2016, Coursera announced the launch of the Master of Computer Science in Data Science from the University of Illinois Urbana-Champaign. At the time, the university's computer-science graduate program was ranked fifth in the United States by U.S. News & World Report. On March 29, 2017, the University of Illinois Urbana-Champaign launched their Master's in Accounting (iMSA) program, now called the Master of Science in Accountancy (iMSA) program. The iMSA program is led through live sessions, headed by UIUC faculty.
Similar to the university's on-campus admission policies, the online master's degrees offered by The University of Illinois through Coursera also has admission requirements. All applicants must hold a bachelor's degree, and have earned a 3.0 GPA or higher in the last two years of study. Additionally, all applicants must prove their proficiency in English.
The University of Illinois also offers online courses in partnership with Coursera, such as Marketing in a Digital World, which focuses on how digital tools like internet, smartphone and 3D printers are changing the marketing landscape.

The complex is also a center for entrepreneurs, and has over 50 startup companies stationed at its EnterpriseWorks Incubator facility.
In 2011, Urbana, Illinois was named number 11 on Popular Mechanics' "14 Best Startup Cities in America" list, in a large part due to the contributions of Research Park's programs. The park has gained recognition from other notable publications, such as inc.com and Forbes magazine. For the 2011 fiscal year, Research Park produced an economic output of $169.5M for the state of Illinois.

### Notable discoveries and innovations

In the field of natural sciences, the BCS theory, a groundbreaking theory of superconductivity, was proposed by John Bardeen in collaboration with Leon Cooper and his doctoral student John Robert Schrieffer. Their work earned them the Nobel Prize in Physics in 1972. In the realm of agricultural science, John Laughnan, while a professor, developed sweet corn with higher-than-normal sugar content, a significant advancement in crop science.
In computer and applied sciences, several notable achievements originated from the University of Illinois. The ILLIAC I, built in 1952, was the first computer entirely constructed and owned by a U.S. educational institution. It was also used by Lejaren Hiller and Leonard Issacson to create the Illiac Suite, the first known composition written by an electronic computer. The development of LLVM, initially started by Vikram Adve and Chris Lattner, is now recognized as a major project in compiler infrastructure. Another milestone was the development of the Mosaic web browser at the National Center for Supercomputing Applications in 1993.
NAMD, a molecular dynamics simulation code, was pioneered by Klaus Schulten and his team at the Beckman Institute for Advanced Science and Technology, further advancing computational biophysics. The PLATO system, also developed at the University of Illinois, was the first generalized computer assisted instruction system, which by the late 1970s supported thousands of terminals globally, introducing many concepts foundational to modern multi-user computing such as forums, instant messaging, and online testing. In terms of interface technologies, Donald Bitzer was instrumental in the 1960s development of both touchscreens and plasma displays. Furthermore, Doug Brown and David R. Woolley created Talkomatic in 1973 on the PLATO system, an early online chat system enabling real-time text communication among small groups.
In the realm of audio-visual technology, Joseph Tykociński-Tykociner publicly demonstrated for the first time a motion picture with a soundtrack optically recorded directly onto the film in 1922.

The university also recruits students from over 100 countries among its 32,878 undergraduate students and 10,245 graduate and professional students. The gender breakdown is 55% men, 45% women. UIUC in 2014 enrolled 4,898 students from China, more than any other American university. They comprise the largest group of international students on the campus, followed by South Korea (1,268 in fall 2014) and India (1,167). Graduate enrollment of Chinese students at UIUC has grown from 649 in 2000 to 1,973 in 2014.

### Student organizations

The university has over 1,000 active registered student organizations, showcased at the start of each academic year during Illinois's "Quad Day." Registration and support is provided by the Student Programs & Activities Office, an administrative arm established in pursuit of the larger social, intellectual, and educative goals of the Illini Student Union. The Office's mission is to "enhance ... classroom education," "meet the needs and desires of the campus community," and "prepare students to be contributing and humane citizens." Beyond student organizations, The Daily Illini is a student-run newspaper that has been published for the community of since 1871. The paper is published by Illini Media Company, a not-for-profit which also prints other publications, and operates WPGU 107.1 FM, a student-run commercial radio station. The Varsity Men's Glee Club is an all-male choir at the University of Illinois that was founded in 1886. The Varsity Men's Glee Club is one of the oldest glee clubs in the United States as well as the oldest registered student organization at the University of Illinois. As of 2018, the university also has the largest chapter of Alpha Phi Omega with over 340 active members.

#### Greek life

There are 59 fraternities and 38 sororities on campus. Of the approximately 30,366 undergraduates, 3,463 are members of sororities and 3,674 are members of fraternities. The Greek system at the University of Illinois Urbana-Champaign has a system of self-government. While staff advisors and directors manage certain aspects of the Greek community, most of the day-to-day operations of the Greek community are governed by the Interfraternity Council and Panhellenic Council. A smaller minority of fraternities and sororities fall under the jurisdiction of the Black Greek Council and United Greek Council; the Black Greek Council serves historically black Greek organizations while the United Greek council comprises other multicultural organizations. Many of the fraternity and sorority houses on campus are on the National Register of Historic Places.

#### Student government

U of I has an extensive history of past student governments. Two years after the university opened in 1868, John Milton Gregory and a group of students created a constitution for a student government. Their governance expanded to the entire university in 1873, having a legislative, executive, and judicial branch. For a period of time, this government had the ability to discipline students. In 1883, however, due to a combination of events from Gregory's resignation to student-faculty infighting, the government formally dissolved itself via plebiscite.
It was not until 1934, when the Student Senate, the next university-wide student government, was created. A year before, future U of I Dean of Students, Fred H. Turner and the university's Senate Committee on Student Affairs gave increased power to the Student Council, an organization primarily known for organizing dances. A year after, the Student Council created a constitution and became the Student Senate, under the oversight of the Committee on Student Affairs. This Student Senate would last for 35 years. The Student Senate changed its purpose and name in 1969, when it became the Undergraduate Student Association (UGSA). It ceased being a representational government, becoming a collective bargaining agency instead. It often worked with the Graduate Student Association to work on various projects
In 1967, Bruce A. Morrison and other U of I graduate founded the Graduate Student Association (GSA). GSA would last until 1978, when it merged with the UGSA to form the Champaign-Urbana Student Association (CUSA). CUSA lasted for only two years when it was replaced by the Student Government Association (SGA) in 1980. SGA lasted for 15 years until it became the Illinois Student Government (ISG) in 1995. ISG lasted until 2004.
The current university student government, created in 2004, is the Illinois Student Senate, a combined undergraduate and graduate student senate with 54 voting members. The student senators are elected by college and represent the students in the Urbana-Champaign Senate (which comprises both faculty and students), as well as on a variety of faculty and administrative committees, and are led by an internally elected executive board of a President, External Vice President, Internal Vice President, and Treasurer. As of 2012, the executive board is supported by an executive staff consisting of a Chief of Staff, Clerk of the Senate, Parliamentarian, Director of Communications, Intern Coordinator, and the Historian of the Senate.

### Residence halls

The university provides housing for undergraduates through 24 residence halls in both Urbana and Champaign. Incoming freshmen are required to live in student housing (campus or certified) their first year on campus. The university also maintains two graduate residence halls, which are restricted to students who are sophomores or above, and three university-owned apartment complexes. Some undergraduates choose to move into apartments or the Greek houses after their first year. There are a number of private dormitories around campus, as well as 15 private, certified residences that partner with the university to offer a variety of different housing options, including ones that are cooperatives, single-gender or religiously affiliated. The university is known for being one of the first universities to provide accommodations for students with disabilities. In 2015, the University of Illinois announced that they would be naming its newest residence hall after Carlos Montezuma also known as Wassaja. Wassaja is the first Native American graduate and is believed to be one of the first Native Americans to receive a medical degree.

### Libraries and museums

Among universities in North America, only the collections of Harvard are larger. Currently, the University of Illinois' 20+ departmental libraries and divisions hold more than 24 million items, including more than 12 million print volumes. As of 2012, it had also the largest "browsable" university library in the United States, with 5 million volumes directly accessible in stacks in a single location. University of Illinois also has the largest public engineering library (Grainger Engineering Library) in the country. In addition to the main library building, which houses numerous subject-oriented libraries, the Isaac Funk Family Library on the South Quad serves the College of Agriculture, Consumer, and Environmental Sciences and the Grainger Engineering Library Information Center serves the College of Engineering on the John Bardeen Quad.
Residence Hall Library System is one of three in the nation. The Residence Hall Libraries were created in 1948 to serve the educational, recreational, and cultural information needs of first- and second-year undergraduate students residing in the residence halls, and the living-learning communities within the residence halls. The collection also serves University Housing staff as well as the larger campus community. The Rare Book & Manuscript Library (RBML) is one of the Special collections units within the University Library. The RBML is one of the largest special collections repositories in the United States.
The university has several museums, galleries, and archives which include Krannert Art Museum, Sousa Archives and Center for American Music and Spurlock Museum. Gallery and exhibit locations include Krannert Center for the Performing Arts and at the School of Art and Design.
The Illinois Open Publishing Network (IOPN) is hosted and coordinated by the University of Illinois Urbana-Champaign Library, offering publishing services to members of the University of Illinois Urbana-Champaign community, to disseminate open access scholarly publications.

### Recreation

The campus has two main recreation facilities, the Activities and Recreation Center (ARC) and the Campus Recreation Center – East (CRCE). Originally known as the Intramural Physical Education Building (IMPE) and opened in 1971, IMPE was renovated in 2006 and reopened in August 2008 as the ARC. The renovations expanded the facility, adding 103,433 square feet to the existing structure and costing $54.9 million. This facility is touted by the university as "one of the country's largest on-campus recreation centers." CRCE was originally known as the Satellite Recreation Center and was opened in 1989. The facility was renovated in 2005 to expand the space and update equipment, officially reopening in March 2005 as CRCE.

### Transportation

The bus system that operates throughout the campus and community is operated by the Champaign-Urbana Mass Transit District. The MTD receives a student-approved transportation fee from the university, which provides unlimited access for university students, faculty, and staff.
Daily Amtrak trains through Illinois Terminal connect Champaign-Urbana with Chicago and Carbondale, Illinois. This includes the corridor service Illini and Saluki and the long-distance City of New Orleans, which provides a direct route to Memphis, Tennessee; Jackson, Mississippi; and New Orleans, Louisiana southbound, in addition to Chicago northbound.
Willard Airport, opened in 1954 and is named for former University of Illinois president Arthur Cutts Willard. The airport is located in Savoy. Willard Airport is home to University research projects, along with flights from American Airlines. In 2013, the university's Institute of Aviation was closed at the University of Illinois and the program was transferred to Parkland College.

### Security

The University of Illinois has a dedicated police department, UIPD, which operates independently from CPD, the department that serves the surrounding Champaign area.
On June 9, 2017, Yingying Zhang, a Chinese international student, was abducted and murdered in a case that made national headlines at the time. The university subsequently announced plans to install additional, high-definition, security cameras across the campus.
On April 18, 2022, Sayed A. Quraishi, a 23-year-old man who had recently graduated from the university, assaulted a Jewish student outside of the campus' Hillel building during an anti-Israel protest organized by Students for Justice in Palestine (SJP). Quraishi was subsequently charged with a hate crime.
In July 2022, the university announced that it was partnering with local businesses to invest $300,000 to combat violent crime in Champaign County.
In September 2022, the City of Champaign transferred responsibility for a large swath of Campustown from CPD (Champaign Police Department) to UIPD, claiming that doing so would reduce response times and improve the quality of service. As part of the jurisdictional reforms, the city agreed to pay a substantial portion of the cost to hire seven new officers to patrol the new coverage area.
Violent crime fell sharply in 2022 compared to the year prior, with shootings and homicides declining by 50 and 47 percent, respectively. The city attributed the decrease in crime to improved staffing levels and the installation of automatic license plate readers.

## Athletics

U of I's Division of Intercollegiate Athletics fields teams for ten men's and eleven women's varsity sports. The university participates in the NCAA's Division I. The university's athletic teams are known as the Fighting Illini. The university operates a number of athletic facilities, including Memorial Stadium for football, the State Farm Center for men's and women's basketball, and the Atkins Tennis Center for men's and women's tennis. The men's NCAA basketball team had a dream run in the 2005 season, with Bruce Weber's Fighting Illini tying the record for most victories in a season. Their run ended 37–2 with a loss to the North Carolina Tar Heels in the national championship game. Illinois is a member of the Big Ten Conference. Notable among a number of songs commonly played and sung at various events such as commencement and convocation, and athletic games are: Illinois Loyalty, the school song; Oskee Wow Wow, the fight song; and Hail to the Orange, the alma mater.
On October 15, 1910, the Illinois football team defeated the University of Chicago Maroons with a score of 3–0 in a game that Illinois claims was the first homecoming game, though several other schools claim to have held the first homecoming as well. On November 10, 2007, the unranked Illinois football team defeated the No. 1 ranked Ohio State football team in Ohio Stadium, the first time that the Illini beat a No. 1 ranked team on the road.
The University of Illinois Ice Arena is home to the university's club college ice hockey team competing at the ACHA Division I level and is also available for recreational use through the Division of Campus Recreation. It was built in 1931 and designed by Chicago architecture firm Holabird and Root, the same firm that designed the University of Illinois Memorial Stadium and Chicago's Soldier Field. It is located on Armory Drive across from the Armory. The structure features four rows of bleacher seating in an elevated balcony that runs the length of the ice rink on either side. These bleachers provide seating for roughly 1,200 fans, with standing room and bench seating available underneath. Because of this set-up the team benches are actually directly underneath the stands.
In 2015, the university began Mandarin Chinese broadcasts of its American football games as a service to its Chinese international students.

### Mascot

The University of Illinois currently has no mascot. Chief Illiniwek, also referred to as "The Chief", was from 1926 to 2007 the official symbol of the University of Illinois in university intercollegiate athletic programs. The Chief was typically portrayed by a student dressed in Sioux regalia. Several groups protested that the use of a Native American figure and indigenous customs in such a manner was inappropriate and promoted ethnic stereotypes. In August 2005, the National Collegiate Athletic Association expressed disapproval of the university's use of a "hostile or abusive" image. While initially proposing a consensus approach to the decision about the Chief, the board in 2007 decided that the Chief, its name, image and regalia should be officially retired. Nevertheless, the controversy continues on campus with some students unofficially maintaining the Chief. Complaints continue that indigenous students feel insulted when images of the Chief continue to be present on campus. The effort to resolve the controversy has included the work of a committee, which issued a report of its "critical conversations" that included over 600 participants representing all sides.
There is a grassroots campaign of students and alumni to officially recognize the belted kingfisher as the mascot of the University of Illinois. Female belted kingfishers are orange and blue (the school's colors) and the bird is native to Illinois. A Kingfisher costume has been created and has made appearances on campus. The campaign to adopt the mascot is not seeking to change the name "Fighting Illini." Multiple Indigenous organizations have also expressed support for the Kingfisher.
