Oregon senior defensive lineman DeForest Buckner's favorite Civil War was in 2013 when the Ducks won at home, 36-35. Marcus Mariota threw a 12-yard touchdown pass to a leaping Josh Huff with 29 seconds left, and the defense held for the victory.
''It was a crazy game,'' Buckner said this week. ''It came down to the wire and I was out there for the last defensive play and it was crazy.''
In that game two years ago, Oregon was coming off a deflating 42-16 loss at Arizona that ended their Pac-12 and national title hopes.
This season, the No. 18 Ducks (8-3, 6-2) won't have a shot at defending their Pac-12 championship or at a Rose Bowl berth. But that doesn't make Friday's game against Oregon State (2-9, 0-8) any less important.
''A rivalry game is a rivalry game no matter what your record is,'' Buckner said. ''Everybody comes out to play. It's a pride thing.''
Beavers running back Storm Barrs-Woods echoed the sentiment:
''Every time we play them, it's a rivalry. I don't care what their record is. I don't care what their ranking is,'' he said. ''It's a rivalry. We hate the Ducks. Ducks hate the Beavers. That's how it goes.''
In that spirit, a look back at some of the more memorable Civil Wars:
THE TOILET BOWL: Everyone's (least) favorite Civil War, a 0-0 tie in the pouring rain. The futile game in November 1983 featured 11 fumbles, five interceptions and four missed field goals. It would go down as the last scoreless Division I college football game.
''It was almost like neither team wanted to win,'' Oregon coach Rich Brooks was quoted as saying.
THE PYRAMID PLAY: The 1933 game was notable because Oregon's extra-point attempt was blocked by Clyde Devine, who was lifted in the air by his teammates. The Ducks nonetheless defeated Oregon State 13-3, and the so-called Pyramid Play was later banned by the NCAA.
HARRINGTON TEARS: In 2000, the No. 8 Beavers denied the fifth-ranked Ducks a trip to Pasadena with a 23-13 victory. Afterward, quarterback Joey Harrington wept in the arms of his father, John, who played the same position for the Ducks in the late 1960s and never beat Oregon State in three tries.
BEAVERS DENIED: In 2008 the Beavers were looking toward their first Rose Bowl in 44 years with a victory in the final game when the Ducks romped to a 65-38 win in Corvallis. The next year the game was dubbed the ''War of the Roses'' because the winner was guaranteed a Rose Bowl berth. Oregon won 37-33.
FINISHING BIG: Jerry Pettibone got his only win after 10 straight losses in his first season as Beavers coach in 1991, when quarterback Ian Shields, playing with a broken big toe, scored on a 6-yard bootleg for the go-ahead touchdown. Oregon State won 14-3, the Beavers' first victory in Eugene in 18 years.
ROSE BOWL BOUND: The Ducks entered the 1994 Civil War tied with USC for the Pac-10 championship and needed a win to clinch their first Rose Bowl berth since 1957. Trailing 13-10, Danny O'Neil drove the team 70 yards, hitting Dino Philyaw for a 19-yard touchdown with 3:47 to play, giving Oregon a 17-13 victory.
THE FLY SWEEP: The Beavers snapped a 10-game winning streak for the home team in the 2007 Civil War when freshman James Rodgers scored on a fly sweep for a 38-31 double-overtime victory. It was Oregon State's last win in the series. On Oregon's chance to answer, the Beavers stuffed Jonathan Stewart on fourth-and-1 from the 16.
THE LAST TIME: Last year's game was an easy 47-19 victory for the Ducks on the road to college football's first playoffs and the national championship game. Mariota, who would go on to win the Heisman Trophy, threw for 367 yards and four touchdowns, while running for two more. In his final college game, Sean Mannion threw for 162 yards and a touchdown, finishing as the Pac-12's all-time leader in passing yards with 13,600.
