Имерина
In early 20th century, the Merina people led an anti-French nationalist movement. The group, based in Antananarivo, was led by a Malagasy Protestant clergyman, Pastor Ravelojoana. A secret society dedicated to affirming Malagasy cultural identity was formed in 1913, calling itself Iron and Stone Network (in local language, Vy Vato Sakelika – VVS). Repressed at first with numerous arrests over 1915 and 1916, the movement re-emerged in the 1920s through communists who gained concessions by partnering with the French Left in France.
