The national flag of Pakistan (Urdu: پاکستان کا قومی پرچم) was adopted in its present form during a meeting of the Constituent Assembly on August 11, 1947, just three days before the country's independence, when it became the official flag of the Dominion of Pakistan. It was afterwards retained by the current-day Islamic Republic of Pakistan. The flag is a green field with a white crescent moon and five-rayed star at its centre, and a vertical white stripe at the hoist side. Though the green colour is mandated only as 'dark green', its official and most consistent representation is Pakistan green, which is shaded distinctively darker. The flag was designed by Amiruddin Kidwai, and is based on the All-India Muslim League flag.

The flag is referred to in the national anthem as Parcham-e-Sitāra-o-Hilāl in Urdu (lit. Flag of the Crescent and Star). It is flown on several important days of the year including Republic Day and Independence Day. A designer named Amiruddin Kidwai studied the League’s flag, as he tried to design a flag for a new, independent nation. Finally he arrived at a design, and he presented it to the men who would run the new Pakistan government. The Pakistan government adopted his design on August 11, 1947. The Pakistan government has pronounced rules about the flying of the Pakistan flag. The government has called for display of the flag at full mast on March 23 of each year. That display recognizes both the adoption of the Lahore Resolution in 1940 and the Declaration of the Republic of Pakistan in 1956. Flag raisers in Pakistan also make a point of hoisting the flag each year on the fourteenth day of August. That is considered to be Pakistan’s Independence Day. Pakistan became free of British control on August 14, 1947.

Pakistan (ⁱ/ˈpækɨstæn/ or ⁱ/pɑːkiˈstɑːn/; Urdu: پاکستان) (Urdu pronunciation: [paːkɪˈst̪aːn] ( listen)), officially the Islamic Republic of Pakistan (Urdu: اسلامی جمہوریۂ پاکستان), is a sovereign country in South Asia. It sits at the crossroads of the strategically important regions of South Asia, Central Asia and the Middle East. It 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 and north, Iran to the southwest and China in the far northeast. It is separated from Tajikistan by Afghanistan's narrow Wakhan Corridor in the north, and it shares a marine border with Oman.

The territory of modern Pakistan was the site of several ancient cultures, including the Neolithic Mehrgarh and the Bronze Age Indus Valley Civilisation, and has undergone invasions or settlements by Hindu, Persian, Indo-Greek, Islamic, Turco-Mongol, Afghan and Sikh cultures. Thus the area has been ruled by numerous empires and dynasties, including the Indian Mauryan Empire, the Persian Achaemenid Empire, the Arab Umayyad Caliphate, the Mongol Empire, the Mughal Empire, the Durrani Empire, the Sikh Empire and the British Empire. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and India's struggle for independence, Pakistan was created in 1947 as an independent nation for Muslims from the regions in the east and west of India 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.
