Petru Rareș

Petru Rareș or Petru IV was twice voivode of Moldavia from 20 January 1527 to 18 September 1538 and from 19 February 1541 to 3 September 1546. He was an illegitimate child born to Stephen the Great. His mother was Maria Răreșoaia of Hârlău, whose existence is not historically documented but who is said to have been the wife of a wealthy boyar fish-merchant nicknamed Rareș "rare-haired". Rareș thus was not Petru's actual name but a nickname of his mother's husband.
