Leftypedia
Leftypedia is a failed "left-unity" and "non-sectarian" encyclopedia founded in 2019. In 2024, after multiple editors voted the make the site officially Marxism–LeninismMarxist-Leninist]], the revisionist administrators purged all Marxist-Leninist editors and installed a tiny rump editorship of mostly left-communists and anarchists. The project has never recovered since.
Although Leftypedia had many flaws during even its height, its external platforms allowed many anti-revisionist Marxist–Leninist editors to organize and eventually form the basis for Revolupedia later in 2024.
