1996 Washington Redskins season: The 1996 Washington Redskins season began with the team trying to improve on their 6–10 record from 1995.  This was the Redskins' last season playing at RFK Stadium, where they had played since 1961.  The Redskins are one of only two teams in NFL history to start the season 7–1 and not make the playoffs, the 2012 Chicago Bears being the other.

2010 Chicago Bears season: The 2010 Chicago Bears season was the franchise's 91st season overall in the National Football League.  Coming off a disappointing 7–9 record in the 2009 season and failing to qualify for the NFL playoffs for a third consecutive season, the Bears sought to develop their roster and improve on their record in 2010, particularly their standing in the NFC North.  All Bears home games were scheduled to be played at Soldier Field.  With their final regular season record at 11–5, the Bears improved drastically on their 2009 record.  Their regular season finished with their first playoff appearance since the Super Bowl season of 2006, winning the NFC North division and earning a bye as the NFC's second seed.  The Bears won their first game in the Divisional round of the playoffs, defeating the Seattle Seahawks on January 16, 2011, to advance to the NFC Championship game.  The Chicago Bears's 2010 season came to an end January 23, 2011 with a 21–14 loss to their longtime rivals and eventual Super Bowl champion Green Bay Packers in the NFC Championship Game.

This was the first time ever that a NATO summit was held in the United States outside of the nation's capital, Washington, D.C.  The event was originally scheduled to coincide and be held after the 2012 G8 summit in Chicago as well, but the G8 summit was later rescheduled to be held at Camp David.

List of Chicago Bears head coaches: This is a complete list of Chicago Bears head coaches.  There have been 18 head coaches for the Chicago Bears, including coaches for the Decatur Staleys (1919–1920) and Chicago Staleys (1921).  The Bears franchise was founded as the Decatur Staleys, a charter member of the American Professional Football Association.  The team moved to Chicago in 1921, and changed its name to the Bears in 1922, the same year the American Professional Football Association (APFA) changed its name to the National Football League (NFL).

Lovie Smith: Lovie Lee Smith (born May 8, 1958) is an American football coach.  He is the head football coach at the University of Illinois.  He was previously the head coach of the Chicago Bears of the National Football League (NFL) from 2004 to 2012, and the NFL's Tampa Bay Buccaneers from 2014 to 2015.  Smith has been to the Super Bowl twice, as the defensive coordinator for the St. Louis Rams and as the head coach for the Bears in 2006.

1925 Chicago Bears season: The 1925 Chicago Bears season was their sixth regular season completed in the National Football League.  The club posted a 9–5–3 record under head coach George Halas earning them a seventh-place finish in the team standings, their worst showing to that date.  However, the 1925 Bears were the most notable team in the young NFL's history to that point—all because of the addition of college star Red Grange.  The Bears started slow, just like in 1924, starting the season with two ties and a loss to Green Bay (the Packers' first win ever over the Bears).  The Bears regrouped, however, and won 6 of their next 7.  More importantly, the college season ended in mid-November and the Bear's owner Halas signed Grange.  Grange was under contract but did not play on November 22 as the Bears defeated the Packers in a rematch.  When Grange did suit up for his first game on Thanksgiving Day against the Cardinals, an estimated 39,000 showed up to see a 0–0 tie.  (A large crowd at that time was about 10,000 fans and most games had less than 5,000 paying customers).  That was just the beginning of 7 games in 18 days for Grange and the Bears, most to enormous crowds.  Over 70,000 showed up on December 6 to see the Bears beat the Giants at the Polo Grounds—this was by far the largest crowd to see a professional football team and the gate receipts saved an ailing Giants franchise.  By the end of the whirlwind football tour, the Bears were exhausted and feebly dropped their last three games, only scoring 6 points total.  Even the lowly Detroit Panthers easily defeated the mighty Bears.  Still, Chicago's success spurred by Grange put the NFL on the "map" and may have saved the league from an early demise.
