"On May 14, 1607, the colonists chose Jamestown Island for their settlement largely because the Virginia Company advised them to select a location that could be easily defended from attacks by other European states that were also establishing New World colonies and were periodically at war with England, notably the Dutch Republic, France, and Spain."
