A a rally held at Petrova Gora on 4 March had a significant impact upon ethnic homogenization. It was not formally associated with any party standing in the election; it was organized by the municipalities of Vojnić and Vrginmost, and the Yugoslav Independent Democratic Party. According to the then-mayor of Vrginmost, the two municipalities had organized the rally to show their support for brotherhood and unity—a Titoist concept whereby all of Yugoslavia's ethnic groups would live in harmony—instead of letting it become a Serb nationalist event. The rally was attended by tens of thousand Serbs who heard mainly pro-Yugoslav speeches about the threat posed by the HDZ and the unfavourable position of Serbs in Croatian society. The SKH-SDP condemned the rally in advance as being harmful to inter-ethnic relations and potentially capable of increasing Croatian nationalism. Croatian media linked the rally to the anti-bureaucratic revolution in neighbouring Serbia and depicted it as a protest demanding the overthrow of the Croatian government. Conversely, Serbian media equated the SKH-SDP with the HDZ, declared the entire Croatian political spectrum nationalist and said Serbs should not take part in Croatia's electoral process.
