Looking at the UFC's champions at the beginning and end of the decade (2010-2019)

Featherweight: Jose Aldo and Alexander Volkanovski

Jose Aldo bought the Featherweight title into the UFC in 2011

The UFC moved the WEC’s Featherweight division into the promotion at the start of 2011, and with it came reigning champion Jose Aldo, who’d held the title since late 2009 and started the decade widely recognized as the best 145 lber on the planet. Aldo would remain in that position until late 2015, when Conor McGregor dethroned him with a first round knockout.

That fight would be the last time we’d see the Irishman at 145 lbs, and Aldo regained the vacant title by defeating Frankie Edgar at UFC 200 in July 2016. In his next title defense however, he was defeated by Max Holloway, who then proved his superiority by stopping Aldo for a second time in a rematch.

After his first defense against Aldo, Holloway put together a further 2 defenses, beating Brian Ortega and Edgar before being dethroned earlier this month by Australia’s Alexander Volkanovski. The Australian's first title defense is expected to be a rematch against Holloway at some point in 2020.
