Georges Pompidou served as Prime Minister under Charles De Gaulle from 1962 until his resignation in 1968 following the events of May and June. He became the longest serving Prime Minister in France and arguably one of the most successful.  His contribution to ending the crisis of May 1968 can be seen as triumphant and he emerged from the events in a much better light than that of his President, De Gaulle. Pompidou's greatest input was the finalisation of the Grenelle accords which were officially passed on June 1st 1968.
