The Montreal Expos (French: Les Expos de Montréal) were a Canadian professional baseball team based in Montreal. The Expos were the first Major League Baseball (MLB) franchise located outside the United States. They played in the National League (NL) East division from 1969 until 2004. After the 2004 season, the franchise moved to Washington, D.C., and became the Washington Nationals.
Immediately after the minor league Triple-A Montreal Royals folded in 1960, political leaders in Montreal sought an MLB franchise, and when the National League evaluated expansion candidates for the 1969 season, it awarded a team to Montreal. Named after the Expo 67 World's Fair, the Expos originally played at Jarry Park Stadium before moving to Olympic Stadium in 1977.
