The complete history of the WWE Championship - Part 19 

Sheamus (November 22, 2015 - December 14, 2015)

Sheamus: Final WWE Championship reign was forgettable

Sheamus had last reigned as a World Champion back in 2012 and had not held the WWE Championship since 2010. He had not been a World title contender since 2013 and had struggled with injuries between 2014 and 2015.

However, he surprisingly won the Money in the Bank contract at the titular pay per view on June 15, 2015 but was not expected to win the title when he cashed in. Sheamus's time as a serious headliner according to most observers was over.

It was a colossal shock then, when Sheamus dethroned Roman Reigns to win the WWE Championship just five minutes and 15 seconds after Reigns had won the strap for the first time at the 2015 Survivor Series.

Reigns, with his victory had refused to join The Authority which necessitated the cash in. Sheamus had no such problems and aligned himself with Triple H and Stephanie McMahon and formed his own squad, monikered The League of Nations, featuring himself, Wade Barrett, Alberto Del Rio and Rusev.

Sheamus would retain the title at TLC on December 13, 2015 but would lose the belt the following night on Raw in a rematch with Reigns.

Sheamus's headline career in WWE was over.
