The Compagnie universelle du canal maritime de Suez was organized at the end of 1858. On 25 April 1859 the first blow of the pickaxe was given by Lesseps at Port Said. During the following ten years, Lesseps had to overcome the continuing opposition of the British government preventing the Sultan from approving the construction of the canal, and at one stage he even had to seek the support of his cousin, Empress Eugenie, to persuade the Emperor Napoleon III to act as arbitrator in the disputes. Finally, on 17 November 1869, the canal was officially opened by the Khedive, Ismail Pasha.
