The Canton Invaders was a professional indoor soccer team from Canton, Ohio. The team played in the American Indoor Soccer Association (AISA). In 1990, this association became the National Professional Soccer League.
The Canton Invaders joined the AISA for the 1984-1985 season. The team was one of the founding members of the league. The Invaders won the league championship in its first two seasons and advanced to the championship series in its third year in the league. During the 1987-1988, 1988-1989, and 1989-1990 seasons, the team reclaimed the league championship. In the 1990-1991 season, the team, now playing in the National Professional Soccer League, returned to the playoffs, although the Invaders lost to the Dayton Dynamo in the semifinals. The Invaders lost to the Detroit Rockers in the championship series during the next season.
Unfortunately for the Invaders and the team�s fans, the squad never attained the success that it enjoyed during its first eight seasons. In the 1992-1993, 1994-1995, and 1995-1996 seasons, the Invaders finished last in the American Division of the National Professional Soccer League. During the 1993-1994 season, the team finished next to last. Due to its poor performance and declining fan support, the Canton Invaders relocated to Columbus, Ohio, and became the Columbus Invaders for the 1996-1997 season. The team performed miserably again, causing the Invaders to disband following this season.
