The “Battle on Tegeler Way” [Schlacht am Tegeler Weg] was a violent confrontation between the police and demonstrators.  The demonstrators were mainly connected with the SDS [Students for Democratic Society] and the APO [Anti-Parliamentary Opposition], who had called for a protest on November 4, 1968 at Tegeler Way in Berlin-Charlottenburg.

In addition to students, many workers and rockers were been among the demonstrators. This street battle is considered a major turning point in the history of the APO in the '68 movement and went down in the history of the political left in Germany.

At the Battle of Tegeler Weg 130 police officers and 22 demonstrators were seriously injured.
