Scottish debt, imperial competition, and political union

A brief aside shifts from the Wars of the Three Kingdoms to Scotland's later contest with England. It presents Scotland's attempt to compete through imperialism as a route to bankruptcy. Foreign debt then created fears that creditors might seize the country, with Denmark named as one possible claimant. Union under the English crown appears in this compressed account as a response to that financial exposure. The passage offers an interpretation of the connection between imperial failure, debt, and political union rather than a full account of the settlement.
