List of Trotskyist internationals
This is a list of the various Trotkyist Internationals. Since the collapse of the Fourth International many Trotskyist parties have attempted to reforge it with like-minded and sister parties. The large number of international tendencies is indicative of the large number of parties and the schisms with the Trotskyist movement. Some of these groups claim to be continuations of the original Fourth International but these claims are not accepted by anyone else.
