Vazul of Hungary

  General Notes:

a Hungarian noble of the Árpád family, Duke between March and Gran or Prince of Nitra, with realm between Morava[disambiguation needed ] (March) and Esztergom (Hran or Gran).

He was the grandson of Taksony. His father was Michael (Mihály), Duke between Morava (March) and Esztergom (Hron or Gran) (\endash ca 978 or bef. 997) and his mother was Michael's wife Adelajda of Poland (\endash aft. 997), daughter or sister of Mieszko I of Poland. His brother was Ladislaus the Bald.
He was a cousin of Stephen I of Hungary. He took part in a conspiracy aimed at murdering king Stephen. As a result of the failed assassination attempt, he was excluded from the royal succession in favour of Pietro Orseolo. As punishment for his treason, Vazul had his eyes gouged out at Nitra Castle and molten lead poured in his ears and his sons were exiled.

Of Vazul's three sons (with his wife N from Tátony family or a woman who may (or may not) have been daughter of Tsar Samuel of Bulgaria, Katun Anastazya) András (Andrew I), Béla and Levente, two would ascend the throne after the dynastic struggle following the death of Stephen I. The line of Árpád kings following Stephen is therefore referred to as the Vazul line.

Vazul married Katun Anastazya of Bulgaria, daughter of Tsar Samuil of Bulgaria and Kosara of Bulgaria.
