The atrocities of World War II make the world realise how vulnerable national constitutional arrangements are. To effectively protect civil rights and liberties, to avoid gross injustices (genocide, discrimination, etc.), and to ensure peace, international cooperation on a global scale is needed. With new international institutions and mechanisms (the United Nations, The Universal Declaration of Human Rights, Human rights treaties, the UN Security Council) the united nations of the world centre on the protection, freedom and welfare of individual human beings regardless where they are or in whatever system they might live. Constitutions everywhere in the world begin express the universal principles of individual autonomy, inalienable human rights, freedoms and the right to self-determination. The implementation of the latter principle heralds in the era of decolonialization. Autocratic systems (classic dictatorships) are pressured under the new universal principles by the international community to set their people free. The new generation of liberation constitutions centre on universal values, with a special focus on self-determination. In the various (new) communist systems that come up this boils down to the right of the workers to determine a socialist (non-capitalist) future with fair labour ship and property relations.
