 Just one year later, Ipswich Town became champions of the Southern Amateur League, clinching the title on the last day of the season.The club won the league a further three times, in 1929–30, 1932–33 and 1933–34, before becoming founder members of the Eastern Counties Football League at the end of the 1934–35 season.In 1936, local businessman Leonard P. Thompson threatened to lead a breakaway from the amateur club to create an entirely separate professional club, Ipswich United.
