The Constitution of the Georgian Democratic Republic was a deeply developed legal document. It took about three years to develop it. Although foreign experts did not participate in the development of the Constitution, its authors nevertheless analyzed all existing and growing democratic trends in the world. The main ideological inspirer was the leader of the Georgian Mensheviks Noe Zhordania. A parliamentary republic was chosen as the form of government. The strong power of the parliament was a distinctive feature of the Georgian statehood of 1918–1921. However, the adoption of the Constitution took place in difficult conditions for the Georgian statehood, during the days of the invasion of the Red Army. For historical and legal science, the Constitution of Georgia of 1921 is an exemplary legal document and a magnificent creation of right-socialist state and legal thought.
