Basarab I of Wallachia

Basarab I unified the territories between the Carpathian Mountains and the Danube River, establishing the Principality of Wallachia. He became its first ruler, creating a political entity that would persist for centuries.

Basarab I led Wallachian forces to victory against the Hungarian army of King Charles I in the Carpathian Mountains. This battle secured Wallachian independence from Hungarian suzerainty and established the Principality of Wallachia as a sovereign state.

Following the Battle of Posada, King Charles I of Hungary recognized Basarab I as ruler of Wallachia. This treaty formalized Wallachian independence and established diplomatic relations between the two kingdoms.
