How did Russian writer Alexander Pushkin die?

Aleksandr Pushkin, in full Aleksandr Sergeyevich Pushkin, (born June 6, 1799, Moscow, Russia—died February 10, 1837, St. Petersburg), as a consequence of being shot in a duel.

Pushkin was just 17 when he made his first challenge to a duel. He was renowned as an expert marksman, but he never shot first in duels and only shed his opponent’s blood once: in his final showdown with d’Anthès.

By the autumn of 1836, Pushkin was falling into greater debt and faced scandalous rumors that his wife was having a love affair with Georges d'Anthès. On 4 November he sent a challenge to a duel to d'Anthès also known as Dantes-Gekkern, Jacob van Heeckeren, and Georges-Charles de Heeckeren d'Anthès. He was a French military officer who lived in Russia in the 1830s.

The duel with d'Anthès took place on 8 February 1837 at the Black River. D'Anthès fired first, critically wounding Pushkin; the bullet entered at his hip and penetrated his abdomen puncturing his bowel. D'Anthès was only lightly wounded in the right arm.

Two days later, on 10 February at 14:45, Pushkin died of peritonitis caused by the fatal wound received at the duel with d’Anthès.
