History
The history of Cappadocia began in prehistoric times. Hatti culture (2500-2000 BC) had its way during the Bronze Age and in about the 2nd Millennium BC the Hittites settled in the region. Soon the Assyrians (2000-1800 BC) had established their trading posts. Phrygians probably ruled Cappadocia from 1250 BC, but the Lydians were expelled by the middle of the 6th century BC by the Persians who ruled until 334 BC. In AD 17 the region became a Roman province, trade and military routes were built and urban centers and settlements were encourage. Once Asia Minor came under Christian influence, the first Christian communities appeared in Cappadocia and those persecuted for their religious beliefs elsewhere sought refuge in the region. Cappadocia thus became a melting pot of a variety of ethnic groups, all of which have influenced the culture and religious beliefs. Basilius the Great (329-379 AD), bishop of Caesarea (modern day Kayseri), inspired many religious colonies and for a thousand years an active monastic way of life endured throughout Cappadocia. Invasions first from Turkmenistan and Mongolia and then from Seljuks and finally Ottomans put an end to the movement.
Geography
Cappadocia lies in central Anatolia, in the heartland of what is now Turkey. The relief consists of a high plateau over 1000 m in altitude that is pierced by volcanic peaks, with Mount Erciyes (ancient Argaeus) near Kayseri (ancient Caesarea) being the tallest at 3916 m. The boundaries of historical Cappadocia are vague, particularly towards the west. To the south, the Taurus Mountains form the boundary with Cilicia and separate Cappadocia from the Mediterranean Sea. To the west, Cappadocia is bounded by the historical regions of Lycaonia to the southwest, and Galatia to the northwest. Due to its inland location and high altitude, Cappadocia has a markedly continental climate, with hot dry summers and cold snowy winters. Rainfall is sparse and the region is largely semi-arid.
Cappadocia contained the sources of the Sarus and Pyramus rivers with their higher affluents, and also the middle course of the Halys, and the whole course of the tributary of the Euphrates later called Tokhma Su. But as no one of these rivers was navigable or served to fertilize the lands along its course, none has much importance in the history of the province.
