Samuel Rawson Gardiner (1829-1902) was a distinguished Victorian historian of the seventeenth century who coined the term 'Puritan Revolution' and was noted for his use of and editorial work on primary sources. This ten-volume work was published in 1883-4, though he had already published eight volumes on the period 1603-37, of which the first two were considerably revised for this edition; and in later works he continued the story through the Civil War, the Commonwealth and the Protectorate. The series was highly regarded in its time, and reprinted often, although it was not without its critics. Gardiner aimed at writing 'scientific history', relying on the facts to speak for themselves. This sixth volume spans the period 1625-9, and includes chapters covering the expedition to Cadiz, the second Parliament of Charles I, the Petition of Right and the impeachment and assassination of the Duke of Buckingham.
