Afġānistān, officially the Islamic Republic of Afghanistan (Pashto: د افغانستان اسلامي جمهوریت, Persian: جمهوری اسلامی افغانستان), is a landlocked country that is located in the heart of Asia. It is variously designated within Central or South Asia, as well as the Middle East.[1][2][3] It has religious, ethno-linguistic, and geographic links with most of its neighbours. It is largely bordered by Pakistan in the south and east, Iran in the west, Turkmenistan, Uzbekistan and Tajikistan in the north, and the People's Republic of China in the far northeast. The name Afghanistan means the "Land of Afghans".

Afghanistan is a culturally mixed nation, a crossroads between the East and the West, and has been ancient focal point of trade and migration. It has an important geostrategical location, connecting South Asia, Central Asia and Middle East together. During its long history, the land has seen various invaders and conquerors, while on the other hand, local entities invaded the surrounding vast regions to form empires to themselves. Ahmad Shah Durrani created a large empire in the middle of the eighteenth century, with its capital at Kandahar.[4] Subsequently, most of its territories were ceded to former neighboring countries. In the 19th century, Afghanistan became a buffer state in "The Great Game" played between the British Empire and Russian Empire. 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 suffered continuous and brutal civil war, which included foreign interventions in the form of the 1979 Soviet invasion of Afghanistan and the 2001 US invasion of Afghanistan in which the ruling Taliban government was toppled. In December 2001, the United Nations Security Council authorized the creation of an International Security Assistance Force (ISAF). This force, composed of NATO troops, has been involved in assisting the government of President Hamid Karzai in establishing authority across the nation. In 2005, the United States and Afghanistan signed a strategic partnership agreement committing both nations to a long-term relationship. In the meantime, about 40 billion US dollars have also been provided by the international community for the reconstruction of the country.
