The claim is supported by historical summaries of the English/British Civil Wars. The National Army Museum says the wars were primarily disputes between Crown and Parliament over how the kingdoms should be governed, but they also had religious and social dimensions; it also notes that some participants sought radical political, social, and religious change. UK Parliament and the University of Cambridge likewise describe major religious and constitutional tensions behind the conflict. So describing the war as "very much about values as well as interests" is accurate.
