The Somers Isles Company was formed in 1615 to operate the English colony of the Somers Isles, also known as Bermuda, as a commercial venture. It held a royal charter for Bermuda until 1684, when it was dissolved, and the Crown assumed responsibility for the administration of Bermuda as a royal colony.

The English overseas possessions, also known as the English colonial empire, comprised a variety of overseas territories that were colonised, conquered, or otherwise acquired by the former Kingdom of England during the centuries before the Acts of Union of 1707 between the Kingdom of England and the Kingdom of Scotland created the Kingdom of Great Britain. The many English possessions then became the foundation of the British Empire and its fast-growing naval and mercantile power, which until then had yet to overtake those of the Dutch Republic, the Kingdom of Portugal, and the Crown of Castile.
