Originally founded simply as Argyle in 1886, the club turned professional and entered both the Southern League and Western League as Plymouth Argyle in 1903. They won the Western League title in 1904–05 and the Southern League title in 1912–13, before winning election into the Football League Third Division in 1920. Finishing as runners-up on six consecutive occasions, they eventually won promotion as Third Division South champions under the long-serving management of Bob Jack in 1929–30. A 20-year stay in the Second Division ended in 1950, though they returned again as Third Division South champions in 1951–52. After another relegation in 1956 they again proved too strong for the third tier, winning the Third Division title not long after in 1958–59.
