Social activism

While at the Lyceum, Pushkin was heavily influenced by the Kantian liberal individualist teachings of Alexander Kunitsyn, whom Pushkin would later commemorate in his poem 19 October. Pushkin also immersed himself in the thought of the French Enlightenment, to which he would remain permanently indebted throughout his life, especially Voltaire, whom he described as "the first to follow the new road, and to bring the lamp of philosophy into the dark archives of history".

Pushkin gradually became committed to social reform, and emerged as a spokesman for literary radicals. That angered the government and led to his transfer from the capital in May 1820. He went to the Caucasus and to Crimea and then to Kamianka and Chișinău in Bessarabia, where he became a Freemason.

He joined the Filiki Eteria, a secret organization whose purpose was to overthrow Ottoman rule in Greece and establish an independent Greek state. He was inspired by the Greek Revolution and when the war against the Ottoman Empire broke out, he kept a diary recording the events of the national uprising.
