Led by Milan Babi? and Milan Marti?, with the support from Serbia, the local Serbs proclaimed SAO Kninska Krajina in August 1990 and began blockading roads connecting Dalmatia to the rest of Croatia. The blockade was mostly made from logs cut down from nearby woods, which is why the event was dubbed the "Log Revolution". The organizers were armed with illegal weapons supplied by Marti?.[1] Since it was planned action, done during the Summer and severed land ties to Dalmatia, high economic damage was done to Croatian tourism.
