unis administration » his administration, its administration, agents administration
2f administration » csf administration, 2.2 administration, trf administration
22great britain » great britain, zgreat britain, great britains
xgreat britain » great britain, zgreat britain, great britains
great brittain » great britain, great britian, great britain's
et colonies » her colonies, des colonies, les colonies
p colonies » _ colonies, her colonies, des colonies

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) OR (((xgreat britain) OR (great brittain)))) %((p colonies) OR (et colonies)) %((2f administration) OR (((unis administration) OR (unix administration))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (((xgreat britain) or (great brittain)))) %((p colonies) or (et colonies)) %((2f administration) or (((unis administration) OR (unix administration))))%22".
• Adding a wildcard symbol may retrieve word variants: %((22great britain) or (((xgreat britain) or (great brittain)))) %((p colonies) or (et colonies)) %((2f administration) or (((unis administration) OR (unix administration))))%22*.
