Vlad II (Romanian: Vlad al II-lea), also known as Vlad Dracul (Vlad al II-lea Dracul) or Vlad the Dragon (before 1395 – November 1447), was Voivode of Wallachia from 1436 to 1442, and again from 1443 to 1447. He is internationally known as the father of Vlad the Impaler, or Dracula. Born an illegitimate son of Mircea I of Wallachia, he spent his youth at the court of Sigismund of Luxembourg, who made him a member of the Order of the Dragon in 1431 (hence his sobriquet). Sigismund also recognized him as the lawful Voivode of Wallachia, allowing him to settle in nearby Transylvania. Vlad could not assert his claim during the life of his half-brother, Alexander I Aldea, who acknowledged the suzerainty of the Ottoman Sultan, Murad II.
After Alexander Aldea died in 1436, Vlad seized Wallachia with Hungarian support. Following the death of Sigismund of Luxembourg in 1437, Hungary's position weakened, causing Vlad to pay homage to Murad II, which included participating in Murad II's invasion of Transylvania in the summer of 1438. John Hunyadi, Voivode of Transylvania, came to Wallachia to convince Vlad to join a crusade against the Ottomans in 1441. After Hunyadi routed an Ottoman army in Transylvania, the sultan ordered Vlad to come to Edirne where he was captured in 1442. Hunyadi invaded Wallachia and made Vlad's cousin, Basarab II, voivode.
