Ranavalona I, also known as Ranavalo-Manjaka I, was sovereign of the Kingdom of Madagascar from 1828 to 1861. After positioning herself as queen following the death of her young husband, Radama I, Ranavalona pursued a policy of isolationism and self-sufficiency, reducing economic and political ties with European powers, repelling a French attack on the coastal town of Foulpointe, and taking vigorous measures to eradicate the small but growing Malagasy Christian movement initiated under Radama I by members of the London Missionary Society. She made heavy use of the traditional practice of fanompoana to complete public works projects and develop a standing army of between 20,000 and 30,000 Merina soldiers, whom she deployed to pacify outlying regions of the island and further expand the realm. The combination of regular warfare, disease, difficult forced labor and harsh trials by ordeal using a poisonous nut from the Tangena shrub resulted in a high mortality rate among both soldiers and civilians during her 33-year reign, with Madagascar's population reducing from 5 million in 1833 to 2.5 million in 1839.
