Viola, Duchess of Opole, also known as Veleslava (Bulgarian: Венцислава), Polish: Wencisława-Wiola; (died 7 September 1251) was a Duchess consort of Opole-Racibórz through her marriage to Casimir I.

Origins

Viola's father's origins are disputed by historians.

• Chronicler Jan Długosz noted that she was originally from Bulgaria.[1][2][3]
• A more popular hypothesis about Viola's parentage was given by Władysław Dziewulski, who stated that she could be the daughter of either Kaloyan of Bulgaria or his successor Boril,[4][5] but this theory has been challenged by Wincenty Swoboda.[6]
• Jerzy Horwat put forward another hypothesis, under which Viola could have been a daughter of either King Béla III from his second marriage to Margaret of France or his son and successor, Emeric.[7]
• Today, historians widely favor that the origins of Viola are unknown.[7]
