Radama II (September 23, 1829  May 12, 1863 [assumed dead]) was the son and heir of Queen Ranavalona I and ruled from 1861 to 1863 over the Kingdom of Madagascar, which controlled virtually the entire island. Radama's rule, although brief, was a pivotal period in the history of the Kingdom of Madagascar. Under the unyielding and often harsh 33-year rule of his mother, Queen Ranavalona I, Madagascar had successfully preserved its cultural and political independence from French and British designs. Rejecting the queen's policy of isolationism and Christian persecution, Radama II permitted religious freedom and re-opened Madagascar to European influence. Under the terms of the Lambert Charter, which Radama secretly contracted in 1855 with French entrepreneur Joseph-Fran?ois Lambert while Ranavalona yet ruled, the French were awarded exclusive rights to the exploitation of large tracts of valuable land and other lucrative resources and projects. This agreement, which was later revoked by Prime Minister Rainilaiarivony, was key to establishing France's claim over Madagascar as a protectorate and, in 1896, as a colony.
