22great britain » great britain, xgreat britain, zgreat britain
2f foreign » 2 foreign, 23 foreign, 24 foreign
22 denmark » 23 denmark, 8.2 denmark, 1.2 denmark
2 denmark » _ denmark, 5 denmark, 4 denmark
3 denmark » _ denmark, 5 denmark, 4 denmark
2f early » 20 early, 21 early, ef early

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22great britain %2f foreign relations %((((22 denmark) OR (2 denmark))) OR (3 denmark)) %2f early works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %2f foreign relations %((((22 denmark) OR (2 denmark))) or (3 denmark)) %2f early works to 1800%22*".
