A Caribbean island was predominantly Irish in the 17th century

In 1678, the Irish accounted for 69% of the total population of Montserrat. This massive presence was explained by the deportation of Irish people from Saint Kitts and Nevis by Thomas Warner, then by the decisions of Oliver Cromwell after the conquest of Ireland in 1649. These indentured servants worked on tobacco and sugar plantations, and could hope to become owners after 7 years of labor.
