This historical study examines the first Protestant missionaries in Madagascar between 1795 and 1827, focusing on the activities and impact of the London Missionary Society during this formative period. Written by Vincent Huyghues-Belrose, the work draws on archival sources to document the challenges, strategies, and cultural encounters faced by early Protestant evangelists on the island. It provides a detailed account of the religious, social, and political dynamics that shaped the introduction of Protestantism in Madagascar, situating the missionary enterprise within the broader context of colonial expansion and cross-cultural exchange in the Indian Ocean region. The book offers valuable insights into the intersection of faith, empire, and local agency during a critical era in Malagasy history.
