London Treaty (1840)
The four powers agreed on joint action in favor of the Turkish sultan Abdülmecid I and against the Egyptian viceroy Muhammad Ali Pasha . This should be obliged to return northern Syria and Cilicia, Crete, areas on the Arabian Peninsula and the Turkish fleet. When he did not respond to an ultimatum, the Allies intervened in Syria. After taking Beirut and other coastal cities and after France gave up its support, Muhammad Ali had to accept the terms in 1841. In return, his rule over Egypt was recognized as hereditary by the European powers.
The Dardanelles Treaty of 1841 is seen as the conclusion of the Oriental Crisis .
