The kingdom of Andrantsay was founded in the 1600s by
Andrianony from
Alasora, a contemporary of
Andriamasinavalona. He built the kingdom by uniting the original inhabitants of the region and migrants from Imerina. During the 18th century, the kingdom became a vassal of
Menabe and many migrants from the West integrated into the kingdom as well as refugees from Imerina kingdoms during the Imerina civil wars. The kingdom is the first inland malagasy kingdom to be documented when the French traveller Nicolas Mayeur reported his time there in his work ''Voyage au pays d'Ancove
. In the late 1790s it was annexed into Imerina kingdom as part of the Imerina enin-toko under the name of Vakinankaratra''. ==Location==
