The Oregon–Oregon State football rivalry (Civil War) is an American college football rivalry game played annually in the state of Oregon between the Ducks of the University of Oregon in Eugene and the Beavers of Oregon State University in Corvallis. First played in 1894, it is the fifth-most played college football rivalry game in the Football Bowl Subdivision. Both universities are members of the North Division of the Pac-12 Conference and the campuses are less than apart in the Willamette Valley. The series has now been played continuously since 1945. Though not officially recognized by the universities, the Platypus Trophy is awarded annually to the winning alumni association. Series history The game was first played in 1894 and has been contested 122 times through 2018, as well as continuously since 1945. Oregon leads the series The game was not held in 1900, 1901, 1911, 1943, and 1944 and two games were played in 1896 and 1945. The first reference to the "Civil War" name was in 1929 and came into common use in 1937. Prior to that, it was called the "Oregon Classic" or the "State Championship Game." The game is usually played in even-numbered years at the home field of Oregon State in Corvallis (Reser Stadium, formerly Parker Stadium, beginning in 1954) and in odd-numbered years at the home field of Oregon in Eugene (since 1967, Autzen Stadium). Seven games were played at Multnomah Field/Stadium (now Providence Park) in Portland: in 1908, 1917, 1933, 1934, 1938, 1950, and 1952. In an effort to mitigate rioting, the 1912 and 1913 games were played at a neutral site in Albany following riots after the 1910 game that led to the 1911 game's cancellation. From 1997 through 2006, the home team won the game. The streak was snapped in 2007, when Oregon State beat Oregon at Autzen Stadium 38–31 in double overtime. In 2008, the Ducks returned the favor in Corvallis by beating OSU 65–38. The streak of visiting teams winning was snapped at two games in 2009 when the Ducks won 37–33 in Eugene. From 1959 to 1961, the Platypus Trophy was awarded to the winner; it was lost for over forty years and finally found in 2005. Beginning with the 2007 game, it is awarded to the winning school's alumni association. A different trophy was awarded following the game in 1980. Both share the longest winning streak in the series
