Dom Carlos I (; English: Charles; 28 September 1863 – 1 February 1908), known as the Diplomat (), the Martyr (Portuguese: o Martirizado), and the Oceanographer (Portuguese: o Oceanógrafo), among many other names, was King of Portugal from 1889 until his assassination in 1908. He was the first Portuguese king to die a violent death since King Sebastian in 1578. Early life Carlos was born in Lisbon, Portugal, the son of King Luís and Queen Maria Pia, daughter of King Victor Emmanuel II of Italy, and was a member of the House of Braganza. He had a brother, Infante Afonso, Duke of Porto. He was baptised with the names Carlos Fernando Luís Maria Víctor Miguel Rafael Gabriel Gonzaga Xavier Francisco de Assis José Simão. He had an intense education and was prepared to rule as a constitutional monarch. In 1883, he traveled to Italy, the United Kingdom, France and Germany, where he increased his knowledge of the modern civilization of his time. In 1883, 1886 and 1888, he ruled as Regent as his father was traveling in Europe, as had become traditional among the Portuguese constitutional kings. His father Luis I advised him to be modest and to study with focus. His first bridal candidate was one of the daughters of German Emperor Frederick III, but the issue of religion presented an insurmountable problem, and diplomatic pressure from the British government prevented the marriage. He then met and married Princess Amélie of Orléans, eldest daughter of Philippe, comte de Paris, pretender to the throne of France. Reign Carlos became king on 19 October 1889. After the 1890 British Ultimatum, a series of treaties were signed with the United Kingdom. One signed in August 1890 defined colonial borders along the Zambezi and Congo rivers, whereas another signed on 14 October 1899 confirmed colonial treaties dating back to the 17th century. These treaties stabilised the political balance in Africa, ending Portuguese claims of sovereignty on the Pink Map, a geographical conception of how Portuguese colonies would appear on a map if the territory between the coastal colonies of Angola and Mozambique could be connected with territory in central Africa. These central African territories became part of the British Empire with the Portuguese concession becoming a source of national resentment in the country. Domestically, Portugal declared bankruptcy twice – on 14 June 1892, then again on 10 May 1902 – causing industrial disturbances,
