In 1657, Oliver Cromwell granted the English East India Company a charter to govern Saint Helena and the following year the company decided to fortify the island and colonise it with planters. The first governor, Captain John Dutton, arrived in 1659, making Saint Helena one of Britain's oldest colonies outside North America and the Caribbean. A fort and houses were built. After the Restoration of the English monarchy in 1660, the East India Company received a royal charter giving it the sole right to fortify and colonise the island. The fort was renamed James Fort and the town Jamestown, in honour of the Duke of York, later James II of England.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What year did the first governor arrive to Saint Helena?
1659
