The author is Priya Satia, and the subtitle is The Violent Making of the Industrial Revolution. Here is one good bit:
In fact, there were so many transitions between peace and war that it is difficult to establish what “normal” economic conditions were. Eighteenth-century Europeans accepted war as “inevitable, an ordinary fact of human existence.” It was an utterly unexceptional state of affairs. For Britons in particular, war was something that happened abroad and that kept truly damaging disruption — invasion or rebellion — at bay. Wars that were disruptive elsewhere were understood as preservationist in Britain…Adam Smith’s complaints about the costs of war, about the “ruinous expedient” of perpetual funding and high public debt in peacetime, staked out a contrarian position; The Wealth of Nations (1776) was a work of persuasion. His and other voices in favor of pacific development grew louder from the margins. By denormalizing war, liberal political economy raised the stakes of the century’s long final wars from 1793 to 1815, which could be stomached only as an exceptional, apocalyptic stage on the way to permanent peace.
In their wake, nineteenth-century Britain packaged their empire as a primarily civilian enterprise focused on liberty, forgetting the earlier collective investment in and profit from the wars that had produced it..
The book offers many points of interest.
