The present book investigates the right to social security in international relations documents. The right to social security has been emphasized particularly in Article 22 of the Universal Declaration of Human Rights and other international documents, and similar to other concepts of human rights has a minimal aspect, that is, all individuals must be enjoyed at least the minimum of facilities, regardless of any bonds, including gender, color, race, religion, etc. and must be protected against social dangers. Welfare and social security are the criteria of the legitimacy of political systems, so that, in the liberal political systems, the duty of the state is not just to protect the community and to guarantee individual freedoms, but the government has a broader responsibility toward society in eliminating inequalities.
