Chiefs–Raiders rivalry

The Chiefs–Raiders rivalry is a National Football League (NFL) rivalry between the Kansas City Chiefs and the Las Vegas Raiders. The rivalry between the Chiefs and Raiders is considered to be one of the NFL's most bitter rivalries. Since the American Football League (AFL) was established in 1960, the Chiefs and Raiders have shared the same division, first being the AFL Western Conference, and since the AFL–NFL merger in, the AFC West.

History
The teams first met in 1960 when the Chiefs were known as the Dallas Texans. The Texans defeated the Raiders 34–16 in the team's first game at Oakland,  then the Raiders defeated the Texans 20–19 at Dallas.

The rivalry did not become so apparent until the Kansas City Athletics baseball team moved to Oakland, California, in 1968. In 1969, the Kansas City Royals expansion team was placed in the same division as the Athletics. The 1966 Chiefs team participated in the first AFL-NFL World Championship Game, later known as the Super Bowl. The Chiefs and Raiders had identical 12–2 records in 1968 and faced off in a playoff game to decide who would go to face the New York Jets for the AFL Championship. The Raiders won, 41–6.

The following year, in 1969, the Raiders beat the Chiefs twice in the regular season and went on to win the AFL Western Conference title. The teams met in the 1969 AFL Championship Game at Oakland and the underdog Chiefs won 17–7. The Chiefs participated in Super Bowl IV a week later and defeated the NFL's heavily favored Minnesota Vikings. It was not until 1976 that Oakland won their first Super Bowl championship.

In the first meeting between the teams during the 1970 NFL season—both teams' first in the newly merged NFL—the Chiefs held a 17–14 lead late in the fourth quarter and appeared ready to run out the clock. Chiefs quarterback Len Dawson rolled right and gained enough yardage for a first down, and as he fell to the ground, Raiders defensive end Ben Davidson dove into Dawson with his helmet; in retaliation, Davidson was attacked by Chiefs wide receiver Otis Taylor. After a bench-clearing brawl, Davidson and Taylor were ejected, and the penalties that were called nullified the first down under the rules at the time. Kansas City was forced to punt. The Raiders took advantage, as George Blanda made a 48-yard field goal with 8 seconds left to secure a 17–17 tie. The tie proved to be costly for the Chiefs, as Oakland clinched their first AFC West championship with a 20–6 victory in Oakland in Week 13. Due to this incident, the NFL changed the rules so that Davidson's personal foul would have been enforced at the end of the play, and Taylor's penalty would have been assessed only after the Chiefs had been awarded a first down.

The Chiefs defeated the Raiders 42–10 in the 1975 season, prompting the Chiefs' live horse mascot Warpaint to circle the field after each touchdown scored. After the game, Raiders coach John Madden said "We couldn't beat the Chiefs, but we damn near killed their horse."

The Raiders won two more Super Bowl titles in 1980 and 1983 while the Chiefs were considered to be one of the worst teams in the NFL. The Raiders won most of the games between the 1970s and 1980s. Following their victory in Super Bowl IV, the Chiefs returned to the playoffs in 1971, but lost in double overtime to the Miami Dolphins in the divisional round in the longest game in NFL history, the final game at Kansas City's Municipal Stadium. Following that loss, Kansas City did not return to the playoffs until 1986.

In the final game of the 1999 season, the Chiefs and Raiders faced off at Kansas City. A win for the Chiefs would put them in the playoffs. A game plagued by special teams mistakes for the Chiefs, including three attempted kickoffs that ended up out of bounds by kickoff specialist Jon Baker, helped keep the Raiders in the game and stop the Chiefs from sealing the victory. The game went into overtime and, helped by favorable field position after the third and final kickoff out of bounds, former Chief Rich Gannon drove the Raiders into Chiefs territory, setting up the game-winning field goal and knocking the Chiefs out of the playoffs, their first win at Arrowhead since 1988.

On October 21, 2007, the Chiefs defeated the Raiders for a record ninth straight victory. On November 25, 2007, the Raiders defeated the Chiefs in Arrowhead for Oakland's first victory over Kansas City since December 23, 2002.

On September 14, 2008, the Raiders defeated the Chiefs 23–8 for the second straight time in Kansas City. Rookie Darren McFadden compiled 210 rushing yards and a touchdown. On November 30, 2008, the Chiefs defeated the Raiders for the sixth straight time in Oakland.

On September 20, 2009, the Raiders defeated the Chiefs 13–10, in Kansas City for the third straight time. The Chiefs became one of the few teams to lose to quarterback JaMarcus Russell. On November 15, 2009, the Chiefs defeated the Raiders 16–10 in Oakland Coliseum for the Chiefs' seventh straight victory in Oakland.

On November 7, 2010, the Raiders defeated the Chiefs in OT 23–20 in a match-up that revived the Chiefs–Raiders rivalry. It marked the 99th time these teams have met in the regular season and 102nd overall. On January 2, 2011, the Raiders defeated the Chiefs in Kansas City for the fourth straight time, 31–10, to finish a sweep of the AFC West.

On October 3, 2011, a Raiders fan filed a lawsuit against the Chiefs and two unidentified Chiefs fans, claiming that security did nothing as he was beaten during a brawl at Kansas City in 2009.

The Chiefs broke Oakland's six-game winning streak in Kansas City on October 13, 2013, when they defeated the Raiders, 24–7, in a game where Kansas City set a then world record for the loudest open-air venue at over 137 dB.

On November 20, 2014, the Raiders snapped a 16-game losing streak in Oakland against the Chiefs while Kansas City was in a four-game winning streak the week after the Chiefs defeated the defending Super Bowl champions, the Seattle Seahawks. The loss ended up costing Kansas City a playoff berth.

In 2015, the Kansas City Chiefs swept the season series between these two teams.

In 2016, both teams were at the top of the AFC for the entire season, with Oakland securing their first winning season and first playoff appearance since 2002. The Chiefs beat Oakland twice, 26–10 in Oakland and in Kansas City 21–13. Both teams ended the regular season with a 12–4 record and with the series sweep, Kansas City won the AFC West and a first round bye while Oakland was relegated to Wild Card status and the fifth seed in the AFC playoffs.

The Chiefs and Raiders met for a Thursday Night match-up on October 19, 2017 in Oakland, with the Chiefs at a 5–1 record and the Raiders at a 2–4 record. The Raiders won the game 31–30 with a touchdown pass at the very end of the game, which followed two Chiefs defensive penalties, also including a scuffle between the two teams that led to Raiders running back Marshawn Lynch getting ejected. The game snapped a four-game losing streak for Oakland in the season, and also a five-game losing streak against the Chiefs in the rivalry.

In Week 5 of the 2020 season, the rivalry between the two teams was renewed when the 2-2 Raiders went to Arrowhead Stadium and upset the undefeated Chiefs 40-32, snapping a 5-game losing streak against the Chiefs dating back to 2017. It was the Raiders’ first win in Arrowhead since 2012, with Derek Carr passing for 347 yards and three touchdowns, while Patrick Mahomes had 340 yards and two touchdowns, but had a costly third-quarter interception that led to a critical Raiders touchdown. It was Mahomes’ first loss to the Raiders, and first loss since losing to the Tennessee Titans in Week 10 of the 2019 season.

On November 22, 2020, the two teams met in Las Vegas for the first time on Sunday Night Football. With 1:07 left in the game, Derek Carr threw a touchdown pass to Jason Witten to give the Raiders a 31-28 lead, but Patrick Mahomes lead a 75-yard drive culminating in a 23-yard touchdown pass to Travis Kelce with 28 seconds left that gave the Chiefs a 35-31 win, officially renewing a spark in the rivalry between the two teams. After, the Chiefs went on to finish the season 14-2, losing to the Buccaneers in Super Bowl LV, while the Raiders, who were 6-3 leading up to this game, began a painful late-season collapse, as they would lose four of their last six games to end the season 8-8 and out of the playoffs.

On Christmas Day, the Raiders defense helped snap another 5-game losing streak against the Chiefs.
