Few Englishmen proved more consistent critics in the years before the Civil War than William Fiennes, Baron, later Viscount, Saye and Sele. In religion a Puritan, in politics committed to the defence of aristocratic privilege and parliamentary rights, he was deeply involved in all of the important opposition movements of the period. A major participant in the passage of the Petition of Right, a prominent opponent of ship-money and the Bishops' Wars with Scotland, he was a leading enemy of the court and clergy in the Long Parliament. Nor was Saye's significance limited to his individual activities alone, for both the Earl of Clarendon and Anthony Wood, writing in the seventeenth century, treated him as the acknowledged leader of the party that provoked the Civil War.
In assessing Lord Saye's role as on opposition leader, historians have paid little attention to Saye's first and, in many ways, most vigorous confrontation with the royal government in 1622. In that year Saye not only refused to contribute to a benevolence for the assistance of Frederick, the Elector — Palatine, but was also accused of attempting to hinder others from doing so. For these alleged actions and the grounds upon which he chose to defend himself, Saye was imprisoned in Fleet Prison for nearly eight months, from June 6, 1622 to February 4, 1622/3.
There are two important documents which will enable us to penetrate the nature of Saye's actions and the government's response to them. The first, hitherto neglected, is a transcript of four appearances which the Baron made before the Council between May 23 and June 6, 1622. The second, a letter from Lord Saye to the Duke of Buckingham, written sometime around February 3, 1622/3, while Saye was still in the Fleet, contains valuable information that has not yet been brought to light concerning this affair.
