Pakistan, officially the Islamic Republic of Pakistan, is a country in South Asia. It is the sixth-most populous country with a population exceeding 199 million people. It is the 36th largest country in the world in terms of area with an area covering 881,913 km2 (340,509 sq mi). Pakistan has a 1,046-kilometre (650 mi) coastline along the Arabian Sea and the Gulf of Oman in the south and is bordered by India to the east, Afghanistan to the west, Iran to the southwest and China in the far northeast respectively. It is separated from Tajikistan by Afghanistan's narrow Wakhan Corridor in the north, and also shares a maritime border with Oman.

The territory that now constitutes Pakistan was previously home to several ancient cultures, including the Mehrgarh of the Neolithic and the Bronze Age Indus Valley Civilisation, and was later home to kingdoms ruled by people of different faiths and cultures, including Hindus, Indo-Greeks, Muslims, Turco-Mongols, Afghans and Sikhs. The area has been ruled by numerous empires and dynasties, including the Indian Mauryan Empire, the Persian Achaemenid Empire, Alexander of Macedonia, the Arab Umayyad Caliphate, the Delhi Sultanate, the Mongol Empire, the Mughal Empire, the Durrani Empire, the Sikh Empire and the British Empire.

Pakistan is unique among Muslim countries as it is the only country to have been created in the name of Islam. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and the subcontinent's struggle for independence, Pakistan was created in 1947 as an independent nation for Muslims from the regions in the east and west of the Subcontinent where there was a Muslim majority. Initially a dominion, Pakistan adopted a new constitution in 1956, becoming an Islamic republic. A civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh.
