Reunion Island is a French overseas department located in the Indian Ocean 550km east of Madagascar. It was formed by volcanic eruptions around 2.5 million years ago and was discovered by Portuguese explorers in the 16th century, though they did not remain on the island. France occupied the island in the 17th century, importing African, Chinese, and Indian slaves and workers until slavery was abolished in 1848. Today, the island is home to people of various ethnicities including French, African, Chinese, Indian, and others, who live in harmony while maintaining their own religious and cultural traditions, as reflected in the food, music, and architecture of Reunion Island.
