August 14th Midnight 1947

Pakistan got its independence from India in august 14th 1947. The day is celebrated all over the country with flag raising ceremonies fireworks take place in the capital city (Islamabad). Pakistan had wanted its independence because they knew that after the British left them then the Hindus were going to take control of the country, they also had known that the Hindus have been Islam's enemy and if they get to control the country then Islam would get finished in Pakistan (that time it was known as India).

"On 3 June 1947, Viscount Louis Mountbatten, the last British Governor-General of India, announced the partitioning of the British Indian Empire into a secular India and a Muslim Pakistan. On 14 August 1947, Pakistan was declared a separate nation from them. At midnight, on 15 August 1947, India became an independent nation. Violent clashes between Hindus and Muslims followed. Prime Minister Nehru and Deputy Prime Minister Sardar Vallabhbhai Patel invited Mountbatten to continue as Governor General of India. He was replaced in June 1948 by Chakravarti Rajagopalachari. Patel took on the responsibility of unifying 565 princely states, steering efforts by his “iron fist in a velvet glove” policies, exemplified by the use of military force to integrate Junagadh, Jammu and Kashmir, and Hyderabad state (Operation Polo) into India. The Constituent Assembly completed the work of drafting the constitution on 26 November 1949; on 26 January 1950 the Republic of India was officially proclaimed. The Constituent Assembly elected Dr. Rajendra Prasad as the first President of India, taking over from Governor General Rajgopalachari. Subsequently, a free and sovereign India absorbed three other territories: Goa (from Portuguese control in 1961), Pondicherry (which the French ceded in 1953–1954) and Sikkim which was absorbed in 1975. In 1952, India held its first general elections, with a voter turnout exceeding 62%." Source and further information: http://en.wikipedia.org/wiki/Indian_independence_movement
