As people are no doubt familiar with by now, the impetus for the American Revolution began with the British needing to pay off their war debt from the Seven Years' War (or the 'French and Indian War' as we in North America call it), and wanting the colonies to pay their fair share of the burden which, to be fair, was accumulated for their defense in a war that began on the North American frontier.
So out of curiosity, I looked at the British war debt, and interestingly enough, it only began growing in the late 17th century with the
War of the Grand Alliance (or the Nine Years War) against King Louis XIV of France, and accelerated through the course of the 18th century particularly with the Seven Years War and the War for American Independence until it reached its peak in the aftermath of the Napoleonic wars:

Indeed, up until the outbreak of the First World War, Britain had almost entirely paid off its war debts over the course of the 19th century. How did it do it? By plundering India?
