The origins of the Group in the first half of the 19th century were marked by the enormous expansion in transportation, with the rush to build canals, railroads and tramways. The period between 1946 and 1955 was dominated by the need for industrial unity in France, which in turn led to the nationalization of Gaz de France. The discovery of natural gas in 1951 led to nothing less than the transformation of the Group between 1956 and 1967 to become a natural gas transporter, supplier and trader. The 1980s marked the beginning of extensive internationalization of the Group's business interests, culminating in the merger between SUEZ and Gaz de France to create a global energy group.
