Super Bowl XVIII was an American football game that was played on January 22, 1984 at Tampa Stadium in Tampa, Florida to decide the National Football League (NFL) champion following the 1983 regular season. The American Football Conference (AFC) champion Los Angeles Raiders (15-4) defeated the National Football Conference (NFC) champion Washington Redskins (16-3), 38–9. The Raiders' 38 points and their 29 point margin of victory were both Super Bowl records until Super Bowl XX. They also outgained the Redskins in total yards 385 to 283.
The win gave the city of Los Angeles its first NFL championship since the 1951 Los Angeles Rams.
The known fact that the Redskins had come into the game as the favored team but left with such a humiliating defeat led Super Bowl XVIII to be known as "Black Sunday," in reference to the Raiders' team colors. It is also an indirect reference to the Thomas Harris novel and 1977 film Black Sunday, which centered around a threatened terrorist attack against a Super Bowl.
Raiders' running back Marcus Allen was the Super Bowl MVP, carrying the ball 20 times, for a then-record total of 191 yards and two touchdowns, including a spectacular 74-yard run in the third quarter. His 74 yard run was also a record (now 2nd to Willie Parker's 75-yard TD run in Super Bowl XL), and his 9.6 yards per carry average was the second highest in Super Bowl history. He also caught 2 passes for 18 yards, giving him 209 total yards from the line of scrimmage in the game. Allen became just the third Heisman Trophy winner to be named Super Bowl Most Valuable Player.
