Concept
Afghanistan, officially the Islamic Emirate of Afghanistan, is a landlocked country located at the crossroads of Central Asia and South Asia. Referred to as the Heart of Asia, it is bordered by Pakistan to the east and south, Iran to the west, Turkmenistan to the northwest, Uzbekistan to the north, Tajikistan to the northeast, and China to the northeast and east. Occupying of land, the country is predominantly mountainous with plains in the north and the southwest, which are separated by the Hindu Kush mountain range. Kabul is the country's largest city and serves as its capital. , Afghanistan's population is 40.2 million (officially estimated to be 32.9 million). Human habitation in Afghanistan dates back to the Middle Paleolithic era, and the country's strategic location along the historic Silk Road has led it to being described, picturesquely, as the 'roundabout of the ancient world'. Popularly referred to as the graveyard of empires, the land has historically been home to various peoples and has witnessed numerous military campaigns, including those by the Persians, Alexander the Great, the Maurya Empire, Arab Muslims, the Mongols, the British, the Soviet Union, and most recently by a US-led coalition. Afghanistan also served as the source from which the Greco-Bactrians and the Mughals, amongst others, rose to form major empires. The various conquests and periods in both the Iranian and Indian cultural spheres made the area a center for Zoroastrianism, Buddhism, Hinduism, and later Islam throughout history. The modern state of Afghanistan began with the Durrani dynasty in the 18th century, with the Durrani Afghan Empire being formed by Ahmad Shah Durrani. The Durrani Empire led conquests in which, at its peak, encompassed land that spanned from eastern Iran to northern India. However, Dost Mohammad Khan is sometimes considered to be the founder of the first modern Afghan state. Following the Durrani Empire's decline and the death of Ahmad Shah Durrani and Timur Shah, a succession crisis occurred between Zaman Shah Durrani, Mahmud Shah Durrani, and Shah Shuja Durrani.
