History of Madagascar
By the 15th century, Europeans had wrested control of the spice trade from the Muslims. They did this by bypassing the Middle East and sending their cargo-ships around the Cape of Good Hope to India. The Portuguese mariner Diogo Dias became the first European to set foot on Madagascar when his ship, bound for India, blew off course in 1500. In the ensuing two-hundred years, the English and French tried (and failed) to establish settlements on the island.
Nosy Be
Nosy Be made first major appearance in Madagascar's history when King Radama I announced that he intended to conquer the whole west of the red island up to the sea. That plan was eventually achieved when the Sakalava Kingdom of Boina came into his possession in 1837 when Queen Tsiomeko's army was defeated. The French colonized the island from 1840, founding an outpost named Hell-Ville (from French Admiral de Hell). In 1849, slavery was abolished by the French, though the slaves were owned by Malagasies. It caused a Malagasy revolt against the French. In the late 19th and early 20th centuries, the island was governed by the French as an internal protectorate within the colony of Madagascar. The French used both military force and diplomacy to maintain their position in the island, appointing the former ruler of Nosy Be Binao as the "gouverneur principal" of the island. Though it was difficult for the French to control the littoral, they founded a plantation colony in Nosy Be, mainly producing sugar and cash crops. 
During the Russo-Japanese War Nosy Be became a supply station for Russia's Second Pacific Squadron. The main fleet led by Admiral Zinovy Rozhestvensky reached Nosy Be on January 9, 1905, where it met a smaller detachment led by Admiral Dmitry von Fölkersam that had arrived already on December 28, 1904. The fleet stayed for two months for refurbishing and coaling, leaving on March 17 to meet its fate ten weeks later at the Battle of Tsushima.
