In the Danish West Indies slaves labored mainly on sugar plantations. Cotton, indigo and other crops were also grown. Sugar mills and plantations dotted the islands hilly landscapes. Each islands economy prospered through sugar plantations and slave trading. While St. John and St. Croix maintained a plantation economy, St. Thomas developed into a prosperous center of trade. Slave rebellion on St. John and St. Croix are well documented. Legitimate trade and business on St. Thomas influenced a different society where many more slaves were given freedom and an opportunity outside of plantation life.
