António de Serpa Pimentel

António de Serpa Pimentel (1825, Coimbra – 1900) was Prime Minister of Portugal from 14 January to 11 October 1890. His term in office began as a reaction to the British ultimatum concerning Portuguese colonial policy in southeast Africa. The signing of the "Treaty of London" later that year, which was intended as a step to resolve the crisis, was viewed as further appeasement of a powerful Britain. This led to his resignation and the fall of his government.
