The International Conference of the Orders and the organizations with similar attributions (CIO) was created in Paris in 1971, on the initiative of Professor LORTAT-JACOB, President of the French Medical Council, and by the Doctors BROCARD and AUTIN, General secretaries of the French Medical Council. The CIO became then the European Conference of the Orders of the Doctors.
In 2008, the Conference is renamed European Council of Medical Orders (CEOM).
