Because of historically poor north–south transport links within Wales (although these have improved in the post World War II years), it was often easier for Welsh clubs to travel east–west, so Welsh clubs tended to look east to England for competitors and many of the top semi-professional sides in Wales played in the English football league system; Bangor City were founder members of the Alliance Premier League (now the National League) in 1979 and reached the FA Trophy final in 1984, before transferring to the new League of Wales in 1992.
