Richeza of Lotharingia was an 11th-century queen consort of Poland and a member of the Ezzonen dynasty. Born in Lorraine around 995, she married Mieszko II Lambert to strengthen political ties between the Polish monarchy and the Holy Roman Empire. Following the political instability and the eventual deposition of her husband, she returned to Germany. Later in life, she became a nun to safeguard her family's heritage and legacy. She is remembered for her role in managing the Ezzonen inheritance and her religious devotion.
