Principality of Hungary

The Grand Principality of Hungary or Duchy of Hungary (Hungarian: Magyar Nagyfejedelemség: "Hungarian Grand Principality", Byzantine Greek: Τουρκία (Tourkia)) was the earliest documented Hungarian state in the Carpathian Basin, established around 895, following the 9th century Magyar invasion of the Carpathian Basin. The Hungarians took possession of the Carpathian Basin in a pre-planned manner, with a long move-in between 862–895.

The Hungarians, a semi-nomadic people, formed a tribal alliance led by Árpád (founder of the Árpád dynasty) who arrived from Etelköz, their earlier principality east of the Carpathians.
