Cassin also headed many Non-Governmental Organisations (NGO), founding the French Federation of Disabled War Veterans in 1918 and until 1940 serving as its President and then Honorary President. In 1945, Charles de Gaulle suggested Cassin, having done so much for the French people, also do something to help the Jewish people. Cassin became the President of the French-Jewish Alliance Israelite Universelle (AIU) which had previously been primarily dedicated to educating Sephardi Jews living under the rule of the Ottoman Empire according to a French modernist curriculum. As President of the AIU, Cassin worked with the American Jewish Committee and the Anglo-Jewish Association, to found the Consultative Council of Jewish Organisations, a network dedicated to building support for Cassin's platform of human rights from a Jewish perspective while the UN human rights system was in its early stages of development. In 2001, CCJO René Cassin was founded in Cassin's to promote Universal Human Rights from a Jewish perspective. The René Cassin medal is awarded by the CCJO to those who have made an outstanding global contribution to human rights. As the head of the Alliance Israélite in France, he pursued civil rights for the Jews and was an active Zionist. A high school in Jerusalem is named after him.
