Vavasor (or Vavasour) Powell (1617 – 27 October 1670) was a Welsh Puritan and Fifth Monarchist, imprisoned for his role in a plot to depose King Charles II.
[4] On 26 December 1641 he was preaching in Llanyre Parish Church in Rhos when he was forcibly removed by Hugh Lloyd and twelve armed men and imprisoned.
[citation needed] In 1646, when Parliament's victory was certain, Powell returned to Wales having received a "certificate of character" from the Westminster Assembly, although he had refused to be ordained by the Presbyterians.
[3] In 1650 Parliament appointed a commission for the better propagation and preaching of the gospel in Wales, with Powell acting as one of the principal advisers of this body.
[3] During his ministry he preached before the Lord Mayor of London (1649), Parliament (1650) and as an ardent defender of Calvinism held disputations with popular Arminians of his day.
Powell has emerged as a leading case study for the right wing elements of seventeenth century English Non Conformity and their relationship to the larger Puritan movement.
