Antigua is an island in the Carribean Islands across the Atlantic Ocean from the English settings of Mansfield Park. Antigua during Austen's time was often known for being a hot location in the Atlantic Slave Trade. Sir Thomas Bertram owns both the estate of Mansfield Park and an estate in Antigua, which is likely utilitzing slavery or in the slave trading business.
