The festivities -- which started on 22 November-- will culminate with concerts and speeches in many cities, notably with one of President Mikheil Saakashvili, one of the key organizers of the November 2003 protests that became known as the Rose Revolution.
Many Georgians have hailed the Rose Revolution as a determining moment in the country's post-Soviet history. Others have grown impatient with the pace of economic and political reforms.
Speaking at an international forum in Tbilisi on 22 November, Saakashvili stressed his government's achievements and said that two years after the Rose Revolution, Georgia's new leadership was "even more united."
Estonian President Arnold Ruutel arrived in Tbilisi late on 22 November to attend the festivities, while Romanian President Traian Basescu and Ukrainian President Viktor Yushchenko were expected in Tbilisi later on 23 November.
