Over the past five years, a project team based at the IIISH has developed the ESTA Database structure in collaboration with international partners. The ESTA project has established a relational database model that is able to accommodate structural differences in source material and (existing) datasets relating to different parts of the Indian Ocean and maritime Asia region. Currently (2023), the database contains almost 8,000 individual slave trade (sub)voyages across the maritime Asia region between roughly 1600 and 1850. The number of enslaved persons transported during these voyages range from 392,000 to 415,000 individuals.
