1996–1997 Serbian protests
In the winter of 1996–1997, university students and Serbian opposition parties organized a series of peaceful protests in the Republic of Serbia (then part of the Federal Republic of Yugoslavia) in response to electoral fraud attempted by the Socialist Party of Serbia of President Slobodan Milošević after the 1996 local elections. During the course of the rallies, students held their protests separately from the citizens' ones, led by opposition then gathered in coalition Zajedno (Together).
