Alexander Sergeyevich Pushkin was a Russian poet, playwright, and novelist of the Romantic era who is considered by many to be the greatest Russian poet and the founder of modern Russian literature. He was born into Russian nobility in Moscow. He published his first poem at the age of 15, and was widely recognized by the literary establishment by the time of his graduation from the Tsarskoye Selo Lyceum. Upon graduation from the Lycee, Pushkin recited his controversial poem "Ode to Liberty", one of several that led to his exile by Tsar Alexander I of Russia. While under the strict surveillance of the Tsar's political police and unable to publish, Pushkin wrote his most famous play, the drama Boris Godunov. His novel in verse, Eugene Onegin, was serialized between 1825 and 1832.
