It's hard to imagine, but through 1976, the Ducks had a losing record against OAC. Post WWII, the Beavers dominated, with Oregon 9-20-2 from 1946-76. But the arrival of Rich Brooks in 1977 brought a change in the rivalry.
According to The Oregonian, Oregon is now 65-47-10 all time against OAC. (Stassen shows fewer wins and fewer losses.) From 1977-2018, the Ducks are 31-10-1 (the Toilet Bowl being the tie). Five Beaver wins occurred from 2000-07, and that stretch includes all of the wins over Oregon by a Beaver team with a winning record since 1977. (There have been only five other winning seasons for OAC since 1977 (1999, 2008, 2009, 2012, 2013). Oregon won the Civil War in each of those years.).
The Ducks have won 10 of the last 11, and 14 of the last 20 Civil Wars.
In 2008, Oregon's 65-38 win deprived OAC of a trip to Pasadena, and in 2009, in the Civil War for the Roses, Oregon earned its first Rose Bowl since 1994 with two fourth down conversions in the closing minutes.
OAC has needed a win in the Civil War to get to .500 in 2001, 2005, 2010, and 2014. Oregon won each of those games.
In 2001, No. 2 Oregon beat OAC when Keenan Howry returned a fourth quarter punt for a touchdown, shortly before a monsoon began. There was no block in the back.
