Francisco Macías Nguema Biyoko

Francisco Macías Nguema (born Mez-m Ngueme, later Africanised to Masie Nguema Biyogo Ñegue Ndong; 1 January 1924 – 29 September 1979), often referred to as Macías Nguema or simply Macías, was an Equatoguinean politician who served as the first president of Equatorial Guinea from the country's gaining of independence in 1968, until his overthrow in 1979. He is widely remembered as one of the most brutal dictators in history. As president, he exhibited bizarre and erratic behavior, to the point that many of his contemporaries believed he was insane.

A member of the Fang people, Macías Nguema held numerous official positions under Spanish colonial rule before being elected the first president of the soon-to-be independent country in 1968. Early in his rule, he consolidated power by establishing an extreme cult of personality and a one-party state ruled by his United National Workers' Party (PUNT), and declaring himself president for life in 1972.

As President, he lacked a coherent political ideology, notably identifying as a "Hitlerian-Marxist" at one point. Domestically, his presidency was characterized by attempts at Africanization and harsh persecution of non-Fang ethnic groups. In foreign policy, he quickly turned against Spain and allied himself with the Eastern Bloc, receiving support from the Soviet Union, Cuba and North Korea, and to a lesser extent, France and its local allies such as Cameroonian President Ahmadou Ahidjo and Gabonese President Omar Bongo, although relations with Cameroon and Gabon collapsed by 1976. Due to his dictatorship's severe human rights abuses and economic mismanagement, tens of thousands of people fled the country to avoid persecution. This led to Equatorial Guinea being internationally nicknamed the "Dachau of Africa". His rule also led to significant brain drain, as intellectuals and educated classes were particular targets for his persecution. In 1979, he was overthrown in a coup d'état by his nephew Teodoro Obiang Nguema Mbasogo and was subsequently tried and executed.

According to various sources, anywhere from 20,000 to 80,000 of the roughly 200,000 to 300,000 people living in the country were killed under his regime, with tens of thousands more fleeing the country. He has been compared to Pol Pot because of the violent, unpredictable, and anti-intellectual nature of his government.
