The Hanoverian king George II of Great Britain was passionately devoted to his family's continental holdings, but his commitments in Germany were counterbalanced by the demands of the British colonies overseas. If war against France for colonial expansion was to be resumed, then Hanover had to be secured against Franco-Prussian attack. France was very much interested in colonial expansion and was willing to exploit the vulnerability of Hanover in war against Great Britain, but it had no desire to divert forces to central Europe for Prussia's interest.
Try to answer this question if possible (otherwise reply "unanswerable"): What was Britain's obligation to Hanover if colonial expansion via war with France was to be resumed?
Hanover had to be secured against Franco-Prussian attack
