Urartu was an Iron Age kingdom centered around Lake Van in the Armenian Highlands. It extended from the eastern bank of the upper Euphrates River to the western shores of Lake Urmia and from the mountains of northern Iraq to the Lesser Caucasus Mountains. Its kings left behind cuneiform inscriptions in the Urartian language, a member of the Hurro-Urartian language family. Since its re-discovery in the 19th century, Urartu, which is commonly believed to have been at least partially Armenian-speaking, has played a significant role in Armenian nationalism.

Lake Van is the largest lake in Turkey and Kurdistan. It lies in the far east of Turkey in the provinces of Van and Bitlis, in the Armenian highlands. It is a saline soda lake, receiving water from many small streams that descend from the surrounding mountains. It is one of the world's few endorheic lakes of size greater than 3,000 square kilometres (1,200 sq mi) and has 38% of the country's surface water. A volcanic eruption blocked its original outlet in prehistoric times. It is situated at 1,640 m (5,380 ft) above sea level. Despite the high altitude and winter averages below 0 °C (32 °F), high salinity usually prevents it from freezing; the shallow northern section can freeze, but rarely.
