Question

without a king hath enjoyed more peace for this last century than any of the monarchical governments in Europe.

Answer 1

It looks like an archaic phrasing. Do you want a modern equivalent, a polished literary version, or to preserve the old style? Here are several options and a brief note on choices:

Notes
- "hath" → modern "has"
- "for this last century" → "over the past century" or "during the last century"
- the phrase "without a king" needs a clear noun to attach to (which country/government?)

Rephrasings
1. Modern, neutral:
- "Has enjoyed more peace over the past century than any of the monarchical governments in Europe."
(Add a subject: e.g., "The republic has enjoyed...")

2. Complete and clear:
- "No country without a king has enjoyed more peace over the past century than the monarchies of Europe."

3. Concise comparison:
- "No republic has been more peaceful in the past century than the European monarchies."

4. Formal/literary (retain some older tone):
- "Without a king, it has enjoyed more peace during the last century than any monarchical government in Europe."

Tell me which tone you prefer and the subject (which country or government), and I can refine further.
