The modern Antifa movement has its roots in the West German Außerparlamentarische Opposition left-wing student movement and largely adopted the aesthetics of the first movement while being ideologically somewhat dissimilar. The first Antifa groups in this tradition were founded by the Maoist Communist League in the early 1970s. From the late 1980s, West Germany's squatter scene and left-wing autonomism movement were the main contributors to the new Antifa movement and in contrast to the earlier movement had a more anarcho-communist leaning. The modern movement has splintered into different groups and factions, including one anti-imperialist and anti-Zionist faction and one anti-German faction who strongly oppose each other, mainly over their views on Israel.

German government institutions like the Federal Office for the Protection of the Constitution and the Federal Agency for Civic Education describe the contemporary Antifa movement as part of the extreme left and as partially violent, and Antifa groups are monitored by the federal office in the context of its legal mandate to combat extremism;[5][6][7][8] the federal office states that the underlying goal of the Antifa movement is "the struggle against the liberal democratic basic order" and capitalism;[7][5] at times the movement has been accused by German authorities of engaging in terrorist acts of violence.[9]
