Muhammad Ali Jinnah was a prominent politician and lawyer, known as 'Quaid-i Azam,' who played a crucial role in Pakistan's independence from India, becoming its first Governor-General. He was born on December 25, 1876, in Karachi, and started his political career in the Indian National Congress before joining the Muslim League, where he advocated for Hindu-Muslim unity and later championed the demand for a separate Muslim state, leading to the creation of Pakistan in 1947. Jinnah's health declined after the partition, and he passed away on September 11, 1948, from tuberculosis and lung cancer.
