The Les engagés du sucre exhibition explores the history and identity of the indentured laborers who worked the island’s sugar plantations after the abolition of slavery. Located at the historic Stella Matutina museum, the project uses archival documents and personal testimonies to document this pivotal era. It serves as a cornerstone of regional identity, reclaiming the stories of the Indian, Chinese, and African workers who built modern Reunion society. Visitors can explore a comprehensive historical narrative that bridges the past with the contemporary diversity of the island. The exhibition has a profound social impact by fostering empathy and a shared understanding of the island’s difficult origins. For researchers, it is a vital archive of the island’s socio-economic history and its global labor connections. Protecting this memory preserves the legacy of the people who shaped the Reunionese multi-ethnic soul.
