evidence: During the 1230s, the Mongol Empire conquered Zakarid Armenia and then the remainder of Armenia. The Mongolian invasions were soon followed by those of other Central Asian tribes, such as the Kara Koyunlu, Timurid dynasty and Ağ Qoyunlu, which continued from the 13th century until the 15th century. After incessant invasions, each bringing destruction to the country, with time Armenia became weakened.[85] [...] Armenia has a territorial area of 29,743 square kilometres (11,484 sq mi). The terrain is mostly mountainous, with fast flowing rivers, and few forests. The land rises to 4,090 metres (13,419 feet) above sea level at Mount Aragats, and no point is below 390 metres (1,280 ft) above sea level.[152] Average elevation of the country area is tenth highest in the world and it has 85.9% mountain area, more than Switzerland or Nepal.[153] Mount Ararat, which was historically part of Armenia, is the highest mountain in the region at 5,137 meters (16,854 feet). Now located in Turkey, but clearly visible from Armenia, it is regarded by the Armenians as a symbol of their land. Because of this, the mountain is present on the Armenian national emblem today.[154][155][156]
