People coming from Europe via the Caucasus, and settling in Cappadocia around 2000 BC, formed an Empire in the region merging with the native people of the area. Their language was of Indo-European origin.
The capital of the Hittite kingdom was at Hattushash (Bogazky), and the other important cities were Alacahyk and Alisar. Hittite remains can be found in all the tumuli in Cappadocia.
The Hittite Empire, which lasted for six centuries in the region, collapsed around 1200 BC when the confederacy of Hittite states was invaded by the Phrygian people from the Balkans.
