Alexander Pushkin was born in Moscow on 6th June 1799. From a young age his nurse taught him all about Russian folktales and traditions. Alexander wasn't a good student, but he loved to read and spent many hours in his father's library. He wrote his first poem at the age of 8 and published his first poem at 15. His work was very different from the other writers at the time and this often got him into trouble with the tsar and the government. For example, one of his most famous plays, Boris Godunov was only published years after he wrote it for political reasons. After marrying a beautiful young girl called Natalya Goncharova in 1831 he continued to write. Millions of people consider his novel, Eugeny Onegin, his poem, The Bronze Horseman and his drama, The Stone Guest, to be masterpieces1. Alexander Pushkin was only 37 when he died. He played a great part in The Golden Age of Russian Literature'. He's Russia's greatest2 poet and national pride.
