Muhammad Ali Jinnah Urdu: (December 25 1876 - September 11 1948) was a Muslim politician and leader of the All India Muslim League who founded Pakistan and served as its first Governor-General. He is officially known in Pakistan as Quaid-e-Azam (Urdu: قائد اعظم — "Great Leader") and Baba-e-Qaum ("Father of the Nation"). His birthday is a national holiday in Pakistan.

Jinnah rose to prominence in the Indian National Congress expounding ideas of Hindu-Muslim unity and helping shape the 1916 Lucknow Pact with the Muslim League; he also became a key leader in the All India Home Rule League. Later Jinnah quit the Congress and took charge of the Muslim League. He proposed a fourteen-point constitutional reform plan to safeguard the political rights of Muslims in a self-governing India. His proposals failed amid the League's disunity, driving a disillusioned Jinnah to live in London for many years.

Several Muslim leaders persuaded Jinnah to return to British India in 1934 and re-organise the League. Jinnah embraced the goal of creating a separate state for Muslims as in the Lahore Resolution. The League won most Muslim seats in the elections of 1946, and Jinnah launched the Direct Action campaign of strikes and protests to achieve an independent Pakistan, which degenerated into communal violence across South Asia. The failure of the Congress-League coalition to govern the country prompted both parties and the British to agree to partition. As Governor-General of Pakistan, Jinnah led efforts to rehabilitate millions of refugees, and to frame national policies on foreign affairs, security and economic development.
