A person who abjures; someone who makes a solemn renunciation of a belief, claim, or allegiance.
From 'abjure' with the agent suffix '-er' (one who does something). It literally means 'one who swears away or renounces.'
Historically, abjurers were often people forced by authorities to publicly reject their religion or political allegiances—making them tragic figures in history, but also sometimes heroes of survival.
