Satyendra Prasanno Sinha, 1st Baron Sinha

Satyendra Prasanno Sinha, 1st Baron Sinha, KCSI, PC, KC, (24 March 1863 – 4 March 1928) was a prominent lawyer and statesman in British India.

Satyendra Prasanno Sinha was born on 24 March 1863 in Raipur, Birbhum in Bengal, British India. His father was the zamindar of Raipur and belonged to the Kayastha caste. He was educated first in Bibhum Zilla School at Suri and then obtained a scholarship to Presidency College, Calcutta, then affiliated to the University of Calcutta, in 1878. He married Gobinda Mohini Mitter on 15 May 1880 at Mahata, Burdwan, Bengal, and in 1881 he abandoned his studies in India to study law in England. Scholarships and prizes enabled him to attend Lincoln's Inn and in 1886 he returned to Calcutta as a barrister.

After returning to India in 1886, Sinha established a successful legal practice in Calcutta. He was a member of the Indian National Congress from 1896 to 1919, when, along with other moderates, he left the organisation. He was elected to preside over the Bombay session of the Congress in 1915.

Sinha became Standing Counsel to the Government of India in 1903. He was the first Indian to be appointed as Advocate-General of Bengal in 1908, and the first Indian member of the Governor-General's Executive Council in 1909. He went to England in 1914 as a member of the War Conference following the outbreak of the First World War, and represented India in Europe's Peace Conference in 1919.

He was knighted in the New Year Honours on 1 January 1915. He was the first Indian to be appointed as Parliamentary Under-Secretary of State for India in 1919. In the same year he was elevated to the peerage as Baron Sinha of Raipur in the Presidency of Bengal, becoming the first Indian member of the British House of Lords, taking his seat in February 1919. After his ennoblement, he navigated a bill through the House of Lords, which became the Government of India Act 1919; the Act transferred legislative power from the Viceroy of India to an Indian Legislature as a step towards self-government. Lord Sinha also became a member of the Imperial Privy Council.

He became Governor of the Province of Bihar and Orissa in 1920, the first Indian to be appointed to such a high rank in the administration of British India. However, in 1921 he retired on the grounds of ill health. In 1926 he became a member of the Judicial Committee of the Privy Council.

Sinha died on 4 March 1928 at Berhampore. He and his wife had seven children.
