Crusaders Football Club is a professional Northern Irish football club, playing in the NIFL Premiership. The club, founded in 1898, is based in north Belfast and plays its home matches at Seaview.
Crusaders originally played as a junior level team until 1921. They then played intermediate level football until 1949, and during that time they were one of the top non-senior teams in the country, winning the Irish Intermediate League nine times and the Steel & Sons Cup on seven occasions. After the withdrawal of Belfast Celtic, Crusaders were elected to the top level in their place, in time for the start of the 1949–50 season. Since then, the club has won 28 senior trophies including seven league titles, four Irish Cups, two League Cups, eight County Antrim Shields, one Setanta Sports Cup, two Gold Cups, three Ulster Cups and one Carlsberg Cup.
