The first issue of the Bolshevik newspaper Pravda was published.

The Bolsheviks, led by Vladimir Lenin, were a radical faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split with the Mensheviks at the Second Party Congress in 1903. The Bolshevik party, formally established in 1912, seized power in Russia in the October Revolution of 1917, and was later renamed the Russian Communist Party, All-Union Communist Party, and ultimately the Communist Party of the Soviet Union. Its ideology, based on Leninist and later Marxist–Leninist principles, became known as Bolshevism.

Pravda is a Russian broadsheet newspaper, and was the official newspaper of the Central Committee of the Communist Party of the Soviet Union, when it was one of the most influential papers in the country with a circulation of 11 million. The newspaper began publication on 5 May 1912 in the Russian Empire but was already extant abroad in January 1911. It emerged as the leading government newspaper of the Soviet Union after the October Revolution. The newspaper was an organ of the Central Committee of the CPSU between 1912 and 1991.
