The Hungarian conquest of the Carpathian Basin, also known as the Hungarian conquest or the Hungarian land-taking (Hungarian: honfoglalás, lit. 'taking/conquest of the homeland'), was a series of historical events ending with the settlement of the Hungarians in Central Europe in the late 9th and early 10th century. Before the arrival of the Hungarians, three early medieval powers, the First Bulgarian Empire, East Francia, and Moravia, had fought each other for control of the Carpathian Basin. They occasionally hired Hungarian horsemen as soldiers. Therefore, the Hungarians who dwelt on the Pontic-Caspian Steppe east of the Carpathian Mountains were familiar with what would become their homeland when their conquest started.
The Hungarian conquest started in the context of a "late or 'small' migration of peoples". The Hungarians took possession of the Carpathian Basin in a pre-planned manner, with a long move-in between 862–895. Other theories assert that the Hungarians crossed the Carpathian Mountains following a joint attack by the Pechenegs and Bulgarians in 894 or 895. They first took control over the lowlands east of the river Danube and attacked and occupied Pannonia (the region to the west of the river) in 900. They exploited internal conflicts in Moravia and annihilated that state sometime between 902 and 906.
