Mircea the Elder was the Voivode of Wallachia from 1386 until his death in 1418. He was the son of Radu I of Wallachia and brother of Dan I of Wallachia, after whose death he inherited the throne.
During the reign of Mircea the Elder, Wallachia controlled the largest area in its history, gaining Dobruja in 1388, the Banate of Severin in 1388/9 and Podunavia. In addition, he was also granted the fiefdoms of Amlaș and Făgăraș in Transylvania.
The byname "elder" was given to him after his death in order to distinguish him from his grandson Mircea II, although some historians believe the epithet was given to him as a sign of respect by later generations.
