Passage: The club was formed in 1899 and turned professional after joining the Midland League in 1912. Crowned Midland League champions in the 192627 and 193839 campaigns, they were elected into the Football League in 1950. They went on to secure promotion as champions of the Third Division North in 195758 and spent six seasons in the Second Division, before they were relegated in 1964 and then down to the Fourth Division in 1968. United spent 34 of the next 37 seasons in the basement tier, punctuated by one-season stays in the third tier after they secured promotions in 197172, 198283 and 199899. Brian Laws saw the club promoted out of League Two at the end of the 200405 season and his successor, Nigel Adkins, led the club to the League One title in 200607. Scunthorpe spent just one season in the Championship, but victory in the 2009 League One play-off Final saw the club promoted back into the Championship. They remained in the second tier until two relegations in as many years saw them back into the fourth tier by 2013. Scunthorpe were again promoted out of League Two at the end of the 201314 campaign, before being relegated back out of League One in 2019.
