1903 - The Russian Social Democratic Labor Party splits into two groups; the Bolsheviks (Russian for "majority") and Mensheviks (Russian for "minority"). (NOTE: Later the Mensheviks became the majority party, meaning that the Mensheviks became the bolsheviks and the Bolsheviks mensheviks).
1967 - Vietnam War: Acting on optimistic reports he was given on November 13, US President Lyndon B. Johnson tells his nation that, while much remained to be done, "We are inflicting greater losses than we're taking...We are making progress." (two months later the Tet Offensive made him regret his words).
