Lazar of Serbia
Mileva Olivera Lazarević (; 1372 – after 1444), also known as Despina Hatun, was a Serbian princess and consort of the Ottoman sultan. She was the youngest daughter of Lazar of Serbia and Princess Milica. She was the wife of Ottoman Sultan Bayezid I, whom she married just after the Battle of Kosovo in 1389 as a pledge of peace between the Lazarević and Ottoman dynasties.
