When football was resumed after the war, Portsmouth won the Southern League for the second time. In the 1920-21 season, Portsmouth saw continuous success finishing 12th that year; they went on to win the League in the 1923-24 season. The club continued with its excellent performance in the Second Division and finished 2nd, thereby winning a promotion during the 1926-27 season with a 9-1 victory over Notts County.
The club’s debut season was a struggle in the First Division. The subsequent season, they lost an important match against Leicester City by 10-0 which is still remembered as a record defeat. However, despite their poor performance throughout the league, Portsmouth managed to reach the FA Cup final but unfortunately they lost to Bolton Wanderers. Portsmouth survived the demotion and the 1933-34 season saw the team reacht the FA Cup Final by defeating Bolton Wanderers, Manchester United, Birmingham City and Leicester City. But despite of all the efforts, the club again suffered defeat in the final against Manchester City. In 1939, Portsmouth reached their third FA Cup Final and defeated Wolves 4-1 comprehensively.
In 1949, Pompey were defeated in the semi-final of the FA Cup by Leicester City but they made up for this defeat in a spectacular fashion by winning the league title. The following year, the club retained the title by defeating Aston Villa on the last day of the season by 5-1. Although the club finished third in 1954-55, in the successive seasons Pompey struggled and were demoted to the Second Division in 1959. In 1961, they were relegated to the Third Division but under the inspired guidance of George Smith they were promoted back to the Second Division. Under his leadership, Portsmouth's maintained their Second Division status throughout the 1960s.
