The Clash of the Avengers was the first open confrontation between the two factions that once made up the Avengers. 

Background

Following the Battle of Sokovia, public opinion worsened as the nations of the world began demanding government oversight. 

The following year, the Avengers were once again thrust into the spotlight after a disastrous operation in Lagos killed twenty-six people, eleven of them being relief workers from Wakanda, and caused $14 million in property damage.

In response, the United Nations passed the Sokovia Accords and established a panel that would control the Avengers' movements. While the team became divided over the impact that the accords would have, with Steve Rogers opposing the idea of international oversight and Tony Stark supporting the idea, the accords were ratified.
