In February 1990, Jovan Rašković founded the Serb Democratic Party (SDS) in Knin, whose program aimed to change the regional division of Croatia to be aligned with ethnic Serb interests. Prominent members of the RSK government, including Milan Babić and Milan Martić, later testified that Belgrade directed a propaganda campaign portraying the Serbs in Croatia as being threatened with genocide by the Croat majority. On 4 March 1990, 50,000 Serbs rallied at Petrova Gora and shouted negative remarks aimed at Tuđman, chanted "This is Serbia", and expressed support for Milošević.
