About Sidónio Pais
Sidónio Bernardino Cardoso da Silva Pais nicknamed "the President-King", was the president of Portugal, serving in 1918. A Portuguese politician, military officer, and diplomat he served as prime minister, minister of war and minister of foreign affairs from 1917 to 1918, minister of finance from 1911 to 1912, and minister of commerce and public works in 1911. His time in politics turned him into one of the most divisive figures in modern Portuguese history, having been referred to by writer Fernando Pessoa as the "President-King", a description that stuck in later years and symbolizes his regime. He is the only Portuguese president to have been assassinated, and the 3rd Portuguese head of state to die a violent death. As a leading Republican, Pais was catapulted into active political life after the establishment of the First Portuguese Republic in 1910. Pais escaped a first assassination attempt on 5 December 1918, during the award ceremony for survivors of the navy trawler Augusto de Castilho. In this post, which he held until 3 November 1911, he represented the government during the festivities that marked the first anniversary of the Republic in the city of Porto.
