In the 1901–02 season, Sunderland won their fifth Football League First Division championship.  They came close to completing the "league and cup double" in the 1912–13 season, winning the league but losing to Aston Villa in the 1913 FA Cup Final.  The team's next success came in the 1935–36 season when they won the League Championship and also the Charity Shield.

In winning promotion the club gained 105 points, which was a record at the time.
