This is the first truly scholarly edition of all the recorded writings and recorded speech acts of Oliver Cromwell (1599-1658) and consists of more than 1,000 texts. Oliver Cromwell, one of Britain's greatest and most controversial generals, rose from lowly provincial origins to preside over the trial and execution of a king, to undertake the most complete conquest of Ireland and Scotland ever achieved, and to spend the last five years of his life as head of state, as Lord Protector of Britain and Ireland. A passionate speaker who claimed to be called by God to overthrow tyranny in church and state, and a powerful advocate for a very broad religious liberty and equality, his speeches and letters reveal the public and the private man more completely than for almost any other early modern political leader. This new edition not only publishes a number of new items, but also edits a large number from recovered originals not previously edited. Every item has its own detailed introduction explaining the status of the text and its context or contexts, but also very full annotation - identifying for example almost every person, place and event mentioned in the text and also - where there is no holograph but also variant copies - all significant differences between variant early copies.
