Big Northern Conference


The Big Northern Conference is an organization of ten high schools in northern Illinois. These high schools are members of the Illinois High School Association.
The high schools of the Big Northern Conference are located in the following counties: Boone, DeKalb, LaSalle, Lee, Ogle, Whiteside, and Winnebago.

History

The conference was formed in 1991 as a football-only union of the Big Eight Conference and the Mid-Northern Conference. The original 12 members consisted of six Big Eight schools, five Mid-Northern schools, and one independent school. Of the remaining football teams from each conference, Pecatonica played in a co-op with Winnebago, Polo and Mt. Morris joined the Upstate Illini Conference, and Huntley played an independent schedule. Pecatonica, Polo, and Mt. Morris all continued to play in the Mid-Northern in other sports, and Huntley continued to do the same in the Big Eight.
In 1995, the Big Eight and Mid Northern merged for all sports, with Ottawa Marquette remaining the only football-only member. Forreston left the conference, moving to the Upstate Illini for all sports. Of the schools from either conference who didn't participate in the football-only merger, Huntley was the only one to join the full merger in 1995, replacing Forreston in football. Pecatonica and Polo joined the Upstate Illini in 1995, while Mt. Morris closed in 1994 and merged with Oregon.
Few more changes occurred over the next 15 years. Johnsburg replaced Ottawa Marquette for football in 1998 after joining the BNC for all other sports in 1997, Huntley left in 2003 to join the Fox Valley Conference and was replaced by Rockford Lutheran, and Johnsburg left in 2006 to join the Fox Valley and was replaced by Boone Community [Unit School District">Boone County, Illinois">Boone Community [Unit School District 200|North Boone].
The conference has had several changes since 2011 and peaked at 16 schools during the 2014–15 and 2015–16 school years. Hampshire left for the Fox Valley Conference in 2011 and was replaced by Rock Falls. Mendota joined for all sports except for football in 2011, but began playing football in the BNC in 2012 along with Rockford Christian who joined that year as a full member. In 2014, Johnsburg rejoined the conference and Dixon became a new member.
Following the 2015–16 school year, Burlington Central, Harvard, Johnsburg, Marengo, and Richmond-Burton left the BNC to join Woodstock and Woodstock North in creating the Kishwaukee River Conference. With 11 schools in the 2016–17 school year, the BNC played as one division for the first time in conference history. In football, BNC schools played against only 8 conference opponents, with the 7 largest schools also playing one game against a team in the KRC.
From 1991–92 to 2005–06, the conference's two divisions for football were determined by school size, with the 6 larger schools in the BNC Red Division and the 6 smaller schools in the BNC White Division. Other sports also used the Red and White divisions from 1995–96 to 2000–01, but switched to East and West divisions in 2001–02. In 2006–07, the BNC permanently switched to East and West divisions for all sports until it ceased having two divisions in 2016–17.
In 2018, Rockford Christian moved to the Northeastern [Athletic Conference (Illinois)|Northeastern Athletic Conference] in football while remaining in the BNC for all other sports. Having 10 teams in football made it possible for the BNC to have a full conference schedule, as there are 9 games in the regular season. Rockford Christian returned to the BNC for football in 2021. Five games into the 2024–25 football season, Rockford Christian cancelled its football season due to low numbers. They planned to switch to eight-man football in 2025, but cancelled their season. The Durand-Pecatonica Coop out of the Northwest Upstate Illini Conference will join the Big Northern Conference in the 2026-2027 school year putting the number of teams back at 10.
Mendota left the conference after the 2020–2021 school year to join the Three Rivers Conference.

Membership timeline

From 1991–92 to 1994–95, the Mid-Northern Conference and Big Eight Conference continued to play all non-football sports in their respective pre-merger conferences, with a full merger happening at the start of the 1995–96 school year. Marengo, which was part of the Northwest Suburban Conference during the 1990–91 school year before joining the BNC for football in 1991, joined the Big Eight for all other sports. Ottawa Marquette was independent in all non-football sports during its entire time associated with the BNC. Huntley did not accompany the other Big Eight schools in the BNC football merger, playing football independently for 1991 and 1992 and in the Upstate Illini Conference for 1993 and 1994. Pecatonica from 1990–91 to 1994–95 was in a co-op with Winnebago for football, but they continued to play separately in the Mid-Northern Conference in other sports..
