In 1685, King James II tried to annul several colonial charters, including CT.The CT colony partitioned the King to keep the Charter or, if it couldn't, to become part of MA.
In 1686, King James sent Sir Edmund Andros to get the CT charter and to establish the Dominion of New England (to include the consolidated colonies of New England, New York, and New Jersey into one viceroyalty).
On 31 October 1687, Andros calls for the CT Charter at the courthouse.Gov. Robert Treat makes a speech and the light "mysteriously" go out.While they're out, Joseph Wadsworth takes the charter and hides it in an oak tree on the Wylly farm (when this tree fell on 20 Aug 1856, it was estimated to be 1,000 yrs. old).
Still, CT fell to King James' rule, as did other northern colonies from ME to the Delaware River, for a couple of years.
In Nov. 1687, Gov. Robert Treat was made part of Gov. Andros' council, and was soon a col. of militia in New Haven co.Andros sought to win him over (due to suspected influence & support he had w/ the people) by conferring offices on him.He had so much influence w/ Andros that CT suffered less from Andros' tyrannous acts.
In April 1689, King James was overthrown in the "Glorious Revolution," the Dominion government collapsed, & Sir Andros was sent back to England.
On 9 May 1689, CT delegates restored Robert Treat to office and reinstated the General Court.
