for Security and Cooperation in Europe (OSCE) set up a mission in Georgia to monitor the peacekeeping operation. From then until mid-2004, South Ossetia was generally peaceful. Following the 2003 Rose Revolution, Mikheil Saakashvili became the President of Georgia in 2004. Ahead of the 2004 parliamentary and presidential elections, he promised to restore the territorial integrity of Georgia.
