Researching Henry Younger

He was a leading Parliamentarian during the English Civil War and worked closely with Oliver Cromwell. He played no part in the execution of King Charles I, and refused to take oaths that expressed approval of the act. Vane served on the Council of State that functioned as the government executive during the Interregnum, but split with Cromwell over issues of governance and removed himself from power when Cromwell dissolved Parliament in 1653. He returned to power during the short-lived Commonwealth period in 1659–1660. His fight for government reform, a constitution along with civil and religious liberties made him a man "Too Dangerous to Let Live" in King Charles' II view. Therefore, he was arrested under orders from King Charles II following his restoration to the throne. After long debate, Vane was exempted from the Indemnity and Oblivion Act, and was thus denied amnesty granted to most people for their roles in the Civil War and Interregnum.

Although he was formally granted clemency by Charles II, he was indicted on high treason by a Middlesex grand jury after charges were presented by the king's attorney general Sir Geoffrey Palmer in 1662. In a court proceeding in which he was denied counsel and the opportunity to properly prepare a defence, he was convicted by a Royalist jury. Charles withdrew his earlier clemency, and Vane was beheaded on Tower Hill on 14 June 1662.

Vane was recognised by his political peers as a competent administrator and a wily and persuasive negotiator and politician. His politics was driven by a desire for religious tolerance in an era when governments were used to establish official churches and suppress dissenting views. Although his views were in a small minority, he was able to successfully build coalitions to advance his agenda. His actions contributed to both the rise and downfall of the English Commonwealth. His books and pamphlets written on political and religious subjects are still analysed today. His writing A Healing Question advocated for a constitutional convention pre-dating the American Constitutional Convention by over a century. Vane is remembered in Massachusetts and Rhode Island as an early champion of freedom.

The New England Historical and Genealogical Society wrote of him in 1848:

Those who have been accustomed to view Roger Williams in his true character, – a great and wonderful man, a pioneer in establishing religious and consequently political liberty, – must accord the same virtues to Sir Henry Vane. It is true, the latter did not lay down his life here in our land, nor was be compelled to fly to the wilderness to enjoy his opinions; but he did die for them, when and where the greatest good would accrue to the world. If Roger Williams deserves all the praise and admiration from posterity which he now has, and which are sure to increase in all future time, Sir Henry Vane certainly deserves no less.
