Kabul is the capital of Afghanistan as well as its largest city, located in the eastern section of the country. According to a 2015 estimate, the population of the city was around 3,678,034 which includes all the major ethnic groups. Rapid urbanization had made Kabul the world's 64th largest city and the fifth fastest-growing city in the world.
Kabul is over 3,500 years old and many empires have controlled the city which is at a strategic location along the trade routes of South and Central Asia. It has been ruled by the Achaemenids, Seleucids, Mauryans, Kushans, Kabul Shahis, Saffarids, Ghaznavids, and Ghurids. Later it was controlled by the Mughal Empire until finally becoming part of the Durrani Empire with help from the Afsharid dynasty.
