Between 1642 and 1651, Charles I and Parliamentary forces fought for control over England, Scotland, and Ireland. The Parliamentary forces won and established the Commonwealth of England. During this period—from the end of the war to the Restoration—what did they call the war that had just ended?
Today, we call it the "English Civil War" or, occasionally, the "War of the Three Kingdoms", but these both strike me as names that would be favored by the royalist side. A quick search on Ngram shows that "civil war", "rebellion", and to a lesser extent "revolution" appeared often in books during the conflict, but all of them dropped off as soon as it was won.
