At the beginning of the 16th century, a Portuguese squadron of 13 ships crisscrossed the Indian Ocean. One of these ships went adrift, and its captain, Diego Diaz, was therefore the first European to discover the Big Island on 10 August 1500. In February 1506, Admiral Herman Suarez recognized the place and so Antomabokala, former capital of Ankarana, acquired its name of Diego Suarez, which comes from the contraction of the first name of the captain and the name of the Admiral. In 1635, the bay was mentioned for the first time under this name by the French pilot Berthelot, author of an oriental map of Africa and
Madagascar. In 1824, the bay was explored by the English hydrographer Owen, then in 1833, Captain Bigeault, commandant of La Nièvre, traveled the North East coast to carry out hydrographic surveys. But this harbor, which is perfectly situated on the route to India, does not fail to interest the European nations and by the Franco-Malagasy treaty of 17 December 1885, France is authorized to occupy Diego Suarez. ==Burma==
