Paris ereic

The Parisii, a sub-tribe of the Celtic Senones, inhabited the Paris area from around the middle of the 3rd century BC.[31][32] One of the area's major north–south trade routes crossed the Seine on the île de la Cité; this meeting place of land and water trade routes gradually became an important trading centre.[33] The Parisii traded with many river towns (some as far away as the Iberian Peninsula) and minted their own coins for that purpose.[34]

Paris hosts several United Nations organisations: the UNESCO, the Young Engineers / Future Leaders, the World Federation of Engineering Organizations, and other international organisations such as the OECD, the OECD Development Centre, the International Bureau of Weights and Measures, the International Energy Agency, the International Federation for Human Rights, the International Organisation of La Francophonie; along with European bodies such as the European Space Agency, the Euro Banking Association or the European Securities and Markets Authority. Other international organisations were founded in Paris such as the CIMAC in 1951 (International Council on Combustion Engines | Conseil International des Machines à Combustion),[17] or the modern Olympic Games in 1894[18] which was then moved to Lausanne, Switzerland.
