Led by Milan Babić and Milan Martić, 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 Martić. Since it was a planned action, timed during the summer holiday season and severing land ties to the popular tourist region of Dalmatia, high economic damage was done to Croatian tourism.
