Tournament format and history
The Illinois High School Boys Basketball Championship is a single-elimination tournament held annually in the spring in the United States. The tournament is organised by the Illinois High School Association (IHSA) and has a long history dating back to 1908.
From its inception in 1908 until 1971, the tournament was a single competition open to nearly all high schools in Illinois. However, in 1972, a significant change was made, and the tournament was divided into two divisions, A and AA, based on school size, with each division crowning its own champion. This format remained in place until 2008, when the tournament underwent further expansion into four separate divisions: 1A, 2A, 3A, and 4A, with the larger schools falling into the higher divisions. The current four-class system assigns teams to a division based on student population, with adjustments made for single-gender schools and those that are not four-year high schools.
The state tournament in each class features the four super-sectional winners, who are randomly drawn to compete against each other in the semifinal round. The winners of the semifinals then advance to the state championship match, while the losers play for third place. The state semifinals are typically held on Fridays, with the championship and third-place games taking place on Saturdays. Classes 1A and 2A share one weekend, while 3A and 4A compete the following weekend.
The Illinois High School Boys Basketball Championship has a rich history and is even credited with coining the term "March Madness" to describe the excitement and intensity of the tournament. In the 2006-07 season, the IHSA celebrated 100 years of the state tournament, honouring a list of "100 Legends" of the boys' basketball tournament. Notable members of this team included Kenny Battle, Lou Boudreau, and Isiah Thomas, among many other basketball greats.

2006-07 season celebrations
The 2006-07 season was a special one for the Illinois High School Boys Basketball Championship, as it marked the 100th anniversary of the IHSA State Tournament. To commemorate this milestone, the IHSA assembled a list of "100 Legends of the IHSA Boys Basketball Tournament." This list included notable alumni such as Kenny Battle, Lou Boudreau, Jim Brewer, and Isiah Thomas. These living legends made special appearances at select games across the state, signing a "Ball of Fame" that was later raffled off at the state tournament. The celebrations also included commemorative books and videos, providing a trip down memory lane for fans and players alike.
The 2006-07 season also witnessed the Illinois Fighting Illini men's basketball team continue their winning ways. Under the guidance of coach Bruce Weber, the team built upon their success from the previous season. Led by a talented group of players, the Fighting Illini achieved a runner-up finish in the Big Ten and advanced to the second round of the NCAA Tournament. Their impressive performance solidified their ranking among the top 17 teams in the nation throughout the season.
During this period, the Illinois High School Boys Basketball Championship underwent a transformation. Up until 2008, the tournament was divided into two divisions, Class A and Class AA, based on school size. Each division crowned its own champion. However, starting with the 2008 season, the tournament expanded to four separate divisions: 1A, 2A, 3A, and 4A, with the larger schools falling into the higher divisions. This change ensured a more balanced competition among schools of similar sizes.
The IHSA Girls Basketball tournament was organized in the same manner as the boys' tournament, with a slight time difference. The girls' tournament commenced two weeks ahead of the boys, ensuring that both tournaments received their fair share of attention and prominence. The dedication to providing equal opportunities for both genders extended beyond the basketball court, with adjustments made for single-gender schools in the class assignments.
The 2006-07 season also served as a reminder of the importance of adhering to rules and regulations. Hales Franciscan's basketball team encountered setbacks due to violations. In 2004, they were removed from the IHSA state series due to recruiting violations. Subsequently, in 2005, their membership was suspended as their recognition by the Illinois State Board of Education (ISBE) had lapsed. As a consequence, Hales Franciscan forfeited all athletic contests played between June 2003 and December 2005, including the 2005 State Championship.
