The territory that now constitutes Pakistan was the site of 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 Persian Achaemenid Empire, Alexander III of Macedon, the Indian Mauryan Empire, the Arab Umayyad Caliphate, the Gupta Empire,the Delhi Sultanate, the Mongol Empire, the Mughal Empire, the Afghan Durrani Empire, the Sikh Empire (partially), and, most recently, the British Empire.
Pakistan 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 Indian subcontinent‘s struggle for independence, Pakistan was created in 1947 as an independent homeland for Indian Muslims. It is an ethnically and linguisticallydiverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic. An ethnic civil war in 1971 resulted in the secession of East Pakistanas the new country of Bangladesh. In 1973 Pakistan adopted a new constitution establishing, alongside its pre-existing parliamentary republic status, a federal government based in Islamabad consisting of four provinces and three federal territories. The new constitution also stipulated that all laws are to conform to the injunctions of Islam as laid down in the Quran and Sunnah.
A regional and middle power, Pakistan has the sixth-largest standing armed forces in the world and is also a nuclear power as well as a declared nuclear-weapons state, the second in South Asia and the only nation in the Muslim world to have that status. Pakistan has a semi-industrialised economy with a well-integrated agriculture sector and a growing services sector. The Pakistani economy is the 24th-largest in the world in terms of purchasing power and the 41st-largest in terms of nominal GDP (World Bank). It is ranked among the emerging and growth-leading economies of the world, and is backed by one of the world’s largest and fastest-growing middle class.
Pakistan’s political history since independence has been characterized by periods of military rule, political instability and conflicts with India. The country continues to face challenging problems, including overpopulation, terrorism, poverty, illiteracy, and corruption. Pakistan is a member of the United Nations, the Shanghai Cooperation Organisation, the Non-Aligned Movement, the Organisation of Islamic Cooperation, the Commonwealth of Nations, the Economic Cooperation Organisation, the South Asian Association for Regional Cooperation, the Developing Eight, and the G20 developing nations, Group of 24, Group of 77, and ECOSOC.
