Between 1600 and 1800 the Dutch East Indian Company VOC shipped estimated 50,000 Indian slaves from Pulicat to Indonesia. They mostly went as bonded labourers to work in Dutch factories (trading posts) and plantations to what was then the Dutch Indies.

The Live history India site has a well written post about this rather hidden past of Pulicat and Dutch: https://www.livehistoryindia.com/cover-story/2019/07/28/pulicat-the-forgotten-indian-slave-trade

The earliest reference to European slave trade is in 1510, when the Portuguese sent 24 slaves from Calicut to Lisbon.
