finance their wars (Britain and France) and powers that needed financial patronage to mobilize and maintain a major military force on the field. Kennedy presents a table (page 81, table 2) of "British Wartime Expenditures and Revenue"; between 1688 and 1815 is especially illustrative, showing that Britain was able to maintain loans at around one-third of British wartime expenditures throughout that period Total wartime expenditures, 1688–1815: £2,293,483,437 Total income: £1,622,924,377 Balance raised by loans: £670,559,060 Loans as per cent of expenditure: 33.3% The chapter also argues that British financial strength was the single most decisive factor in its victories over France during the 18th century. This chapter ends on the Napoleonic Wars and the fusion of British financial strength with a newfound industrial strength. Industrial Revolution Kennedy's next two chapters depend greatly upon Bairoch's calculations of industrialization, measuring all nations by an index, where 100 is the British per capita industrialization rate in 1900. The United Kingdom grows from 10 in 1750, to 16 in 1800, 25 in 1830, 64 in 1860, 87 in 1880, to 100 in 1900 (page 149). In contrast, France's per capita industrialization was 9 in 1750, 9 in 1800, 12 in 1830, 20 in 1860, 28 in 1880, and 39 in 1900. Relative shares of world manufacturing output (also first appearing on page 149) are used to estimate the peaks and troughs of power for major states. China, for example, begins with 32.8% of global manufacturing in 1750 and plummets after the First Opium War, Second Opium War and Taiping Rebellion to 19.7% of global manufacturing in 1860, and 12.5% in 1880 (compared to the UK's 1.9% in 1750, growing to 19.9% in 1860, and 22.9% in 1880). 20th century Measures of strength in the 20th century (pages 199–203) use population size, urbanization rates, Bairoch's per capita levels of industrialization, iron and steel production, energy consumption (measured in millions of metric tons of coal equivalent), and total industrial output of the powers (measured against Britain's 1900 figure of 100), to gauge the strength of the various great powers. Kennedy also emphasizes productivity increase, based on systematic interventions, which led to economic growth and prosperity for great powers in the 20th century. He compares the great powers at the close of the 20th century and predicts the decline of the Soviet Union, the rise of China and Japan, the struggles and potential for the European Economic
