2f foreign » 2 foreign, 23 foreign, 22 foreign
24 foreign » 2 foreign, 14 foreign, 23 foreign

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) OR (((24 foreign) OR (4 foreign)))) relations %((8.2 denmark) OR (23 denmark)) %((2f early) OR (20 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %((2f foreign) or (((24 foreign) OR (4 foreign)))) relations %((8.2 denmark) or (23 denmark)) %((2f early) or (20 early)) works to 1800%22*".
