Lesseps steadily endeavored to keep out of politics. If in 1869 he appeared to deviate from this principle by being a candidate at Marseille for the Corps Législatif, it was because he yielded to the entreaties of the Imperial government in order to strengthen its goodwill for the Suez Canal. Once this goodwill had been shown, he bore no malice towards those who rendered him his liberty by preferring Léon Gambetta. Afterward, Lesseps declined the other candidatures that were offered to him: for the Senate in 1876, and for the Chamber in 1877. In 1873 he became interested in a project for uniting Europe and Asia by a railway to Mumbai, with a branch to Beijing. The same year, he became a member of the French Academy of Sciences. He subsequently encouraged Major Roudaire, who wished to transform a stretch of the Sahara into an inland sea to increase rainfall in Algeria.
