Marie Alexandrine Becker (née Petitjean; 14 July 1879 – 11 June 1942), nicknamed The Black Widow, was a Belgian serial killer who was sentenced to death for poisoning eleven people between 1933 and 1936, and attempting to poison five others. Since capital punishment in Belgium had not been applied since 1863, her sentence was commuted to life imprisonment.

Ante Pavelić (Croatian: [ǎːnte pǎʋelit͡ɕ] ; 14 July 1889 – 28 December 1959) was a Croatian politician who founded and headed the Ustaše in 1929 and was dictator of the Independent State of Croatia (NDH), a fascist puppet state built out of parts of occupied Yugoslavia by the authorities of Nazi Germany and Fascist Italy, from 1941 to 1945. Pavelić and the Ustaše persecuted many racial minorities and political opponents in the NDH during the war, including Serbs, Jews, Romani, and Yugoslav Partisans, becoming one of the key figures of the genocide of Serbs, the Porajmos and the Holocaust in the NDH.
