the colony's foreign neighbors, opposing official intervention in a French Acadian dispute in the 1640s, and also spoke against attacking the New Netherland during the First Anglo-Dutch War (1652–1654). Bradstreet was sent on a number of diplomatic missions, dealing with settlers, other English colonies, and the Dutch in New Amsterdam. In 1650 he was sent to Hartford, Connecticut, where the Treaty of Hartford was negotiated to determine the boundary between the English colonies and New Amsterdam. In the following years he negotiated an agreement with settlers in York and Kittery to bring them under Massachusetts jurisdiction. Following the 1660 restoration of Charles II to the throne of England, colonial authorities again became concerned about preserving their charter rights. Bradstreet in 1661 headed a legislative committee to "consider and debate such matters touching their patent rights, and privileges, and duty to his Majesty, as should to them seem proper." The letter the committee drafted reiterated the colony's charter rights, and also included declarations of allegiance and loyalty to the crown. Bradstreet and John Norton were chosen as agents to deliver the letter to London. Charles renewed the charter, but sent the agents back to Massachusetts with a letter attaching conditions to his assent. The colony was expected, among other things, to expand religious tolerance to include the Church of England and religious minorities like the Quakers. The agents were harshly criticized by hardline factions of the legislature, but Bradstreet defended the need to accommodate the king's wishes as the safest course to take. How to respond to the king's demands divided the colony; Bradstreet was part of the moderate "accommodationist" faction arguing that the colony should obey the king's wishes. This faction lost the debate to the hardline "commonwealth" faction, who were in favor of aggressively maintaining the colony's charter rights, led through the 1660s by governors John Endecott and Richard Bellingham. With Charles distracted by war with the Dutch and domestic politics in the late 1660s, the issue lay dormant until the mid-1670s. Relations between colony and crown deteriorated when the king then renewed demands for legislative and religious reforms, which hardline magistrates again resisted. Governor In early 1679 Governor John Leverett died, and Bradstreet as deputy succeeded him. Leverett had opposed accommodation of the king's demands, and the change to an accommodationist leadership was too late. Bradstreet would turn out to be the last governor under its original charter.
