Many of English football's most famous and successful clubs reached low ebbs during the 1970s and 1980s, in many cases at least partly due to financial problems. Preston North End and Blackpool both fell into the Fourth Division and had to apply for re-election to the Football League between 1982 and 1986. Wolverhampton Wanderers found themselves on the verge of closure twice during the 1980s and suffered three successive relegation which pushed them into the Fourth Division in 1986. Their local rivals Birmingham City dropped into the Third Division for the first time in 1989. Sunderland suffered the same fate as Birmingham two years previously, but achieved promotion at the first attempt and were soon challenging for a return to the First Division, while Wolves ended the decade back in the Second Division after two successive promotions. Bolton Wanderers, four times FA Cup winners, were relegated to the Fourth Division in 1987, but were promoted at the first time of asking.
