 The development of the Hungarian language started around 800 BC with the withdrawal of the grasslands and the parallel southward migration of the nomadic Ugric groups. The history of the ancient Magyars during the next thousand years is uncertain; they lived in the steppes but the location of their Urheimat is subject to scholarly debates. According to one theory, they initially lived east of the Urals and migrated west to "Magna Hungaria" by 600 AD at the latest. Other scholars say Magna Hungaria was the Magyars' original homeland, from where they moved either to the region of the Don River or towards the Kuban River before the 830s AD. Hundreds of loan words adopted from Chuvash-type Turkic languages prove the Magyars were closely connected to Turkic peoples. Byzantine and Muslim authors regarded them as a Turkic people in the 9th and 10th centuries.
