Sam, here's a link to an audio series on The History of the Reformation; within this series, you'll find SEVEN HOURS of lectures regarding the history of Olivor Cromwell.

I think that if you listen to this series, you'll find a fairly complete history of Olivor Cromwell; and that he has been a much maligned historical figure.
Thanks for that. I think I will start at the beginning of the series so it will take a little time to get to Cromwell. And I love Calvinists. They may have been overly dogmatic but if it wasnt for their challenge to established religious and political norms, we may never have had Puritans making their way to the New World to establish the freest civilization man has ever known.
Listening to the first in the series. I got to tell you the lecturer pulls no punches. I forgot what a real demon King Charles was - brining foreigners, Catholics and Irishmen against free English peoples.
