The national flag of Pakistan (Urdu: پاکستان کا قومی پرچم, Pākistān kā Qaumī Pārc̱am) 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 center, and a vertical white stripe at the hoist side. Though the green color 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 the 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 was carved out from British India as a home to Indian Muslims.
Before the Second World War, Muslims and Hindus lived together under the British Raj. A number of the Muslims formed the All India Muslim League. After the Second World War, when the partition of India led to the creation of Dominion of Pakistan, the flag of the Muslim League served as the basis for the flag of Pakistan.
The green represents Islam and the majority Muslims in Pakistan and the white stripe represents religious minorities and minority religions. In the centre, the crescent and star symbolizes progress and light respectively. The flag symbolizes Pakistan's commitment to Islam and the rights of religious minorities. It is based on the original flag of the Muslim League, which itself drew inspiration from the flag of the Sultanate of Delhi and the Flag of the Mughal Empire.
The official design of the national flag was adopted by the Constituent Assembly together with a definition of the features and proportions.
According to the specifications it is a dark green rectangular flag in the proportion of length [A] and width [B] as 3:2 with a white vertical bar at the mast, the green portion bearing a white crescent in the centre and a five-pointed white heraldic star. The size of the white portion is one quarter the size of the flag [C], nearest the mast, so the green portion occupies the remaining three quarters [D].
