St. Domingo is the capital city of the Dominican Republic, a country sharing one island with Haiti near the Gulf of Mexico. Frederick Wentworth was stationed in St. Domingo with the Royal Navy before he met Anne Elliot and fell in love with her: "He was...a captain Frederick Wentworth...who being made commander in consequence of the action off St. Domingo, and not immediately employed, had come into Somersetshire, in the summer of 1806...[Frederick Wentworth and Anne Elliot] were gradually acquainted, and, when acquainted, rapidly and deeply in love" (Austen 65). It is reasonable to believe that the UK's involvement in St. Domingo was related to the Atlantic Slave Trade. Businesses and estate owners in St. Domingo were openly exploiting enslaved people for work here.
