In 1482, Andry Ralofoaro integrated Sakalava and Sanafah into the Empire of Madagasikara, which would go on to include Betsileo and Toamisina, covering the entirety of the island of Madagascar.
The Chiefdom of Sakalava emerged in 1435, as with all other Malagasy states, in response to the expansion of the Mamluk Sultanate on the Malagasy island. The Chiefdom was relatively decentralized but was one of the most powerful chiefdoms in this period.
Union with Sanafah
In the Sanafahi Civil War, many Sakalavan citizens of Sanafah wanted have Sanafah and Sakalava enter into a tribal confederation based upon common ethnic ties and pushed the Sakalavan heir forward as an alternative to the Cairo-backed Emir. Tiavina Ralofoaro was quick to seize the chance and was made Chief of Sanafah in addition to Chief of Sakalava.
Annexation and the Madagasikaran Civil War
Following the arrival of Christians and Spaniards to Madagascar in 1471, Sakalava and the Sakalavan people began to convert to Christianity and use the Latinized Malagasy tongue developed by Spanish priest Julio Marciana Gabriel. This drew the two Sakalavan states closer together, and integration of the two nations was a primary goal of Andry Ralofoaro who was crowned Chief following the death of his father, Tiavina.
