Rabesahala became the secretary general of the "Comité de Solidarité Malgache" (Malagasy Solidity Committee), an organisation created in the following day of the events that bloodied Madagascar, still under colonial administration. At the time, the objectives of the association were to create a broad movement of solidarity that worked to defend the victims of French colonial repression following the 1947 Malagasy Uprising. The success was the culmination of nine years of uninterrupted struggle for justice, freedom and national dignity, which was joined by people of heart in France and throughout the world. In 1960, when independence was regained, the association changed its focus to development activities, giving priority to the fields of education and health, in addition to helping the most destitute and the victims of natural disasters.
