“Tankies” is a pejorative term used to describe hardline supporters of authoritarian communist regimes, particularly those who defend the actions of the Soviet Union during events like the Hungarian Revolution of 1956 and the Prague Spring in 1968. The term has evolved to also refer to modern supporters of similar ideologies, including those who back policies of countries like Russia and China.
