Hitler committed suicide on April 30, 1945, to avoid being captured by the Soviet Red Army that was advancing in Berlin.

Joseph Stalin (1878 – 1953)

The Georgian-born Soviet leader rose to power after Lenin’s death in 1924.

The number of casualties of the Stalinist regime varies. Still, about 14 to 20 million people are estimated to have died in the penalty labor camps known as the gulags or were executed during the Great Purge in the 1930s, while millions were deported and exiled.

He found refuge in Libya and then in Saudi Arabia, where he died in 2003.

Augusto Pinochet (1915 – 2006)

A military dictator who came to power in a coup d’etat in 1973 held power in Chile for nearly 20 years, during which he brutally suppressed his opponents. More than 100,000 people were arrested only during the first three years. Pinochet stepped down as President of Chile in 1990 after the Chileans voted against the continuity of his presidency on a plebiscite. In the early 2000s, he was trialed for violations of human rights, but the court ruled that he was mentally unfit for the trial.

Francois Duvalier (1907 – 1971)

The Haitian dictator, also known as Papa Doc, governed the Americas' poorest country from 1957 to he died in 1971. During his reign of terror, about 30,000 Haitians are estimated to have been assassinated, while thousands – mostly intelligence fled the country. Many people consider him responsible for the current situation in Haiti. He was succeeded by his son Jean-Claude Duvalier who continued the reign of terror until 1986 when he went into a self-imposed exile.

Francisco Franco (1892 – 1975)

The Spanish dictator held power from 1939 when he emerged as the winner of the Spanish Civil War until his death in 1975. His regime was marked by severe repression and systematic suppression of dissidents who were either sent to concentration camps, sentenced to prison, which often includes forced labor or executed. The Francoist regime became more liberal in the 1960s and 1970s, but Spain became a democratic country only after Franco’s death.
