Afghanistan is a crossroads between the East and the West, and was an ancient focal point of the Silk Road and migration. It has an important geostrategic location, connecting South and Central Asia and Middle East. Because of this, the land has been a target of various invaders and conquerors, as well as a source from which local powers invaded surrounding regions to form their own empires. Ahmad Shah Durrani created the Durrani Empire in 1747, which is considered the beginning of modern Afghanistan.[10] Subsequently, the capital was shifted to Kabul and most of its territories ceded to former neighboring countries. In the late 19th century, Afghanistan became a buffer state in "The Great Game" played between the British Indian Empire and Russian Empire.[11] On August 19, 1919, following the third Anglo-Afghan war, the country regained full independence from the United Kingdom over its foreign affairs.
Since the late 1970s Afghanistan has experienced a continuous state of civil war punctuated by foreign occupations in the forms of the 1979 Soviet invasion and the 2001 U.S.-led invasion that toppled the Taliban government. In late 2001 the United Nations Security Council authorized the creation of an International Security Assistance Force (ISAF) composed of NATO troops.
