Until the middle years of the nineteenth century Britain led the world in industrial production; free trade guaranteed access to world markets because no other country could manufacture so much so cheaply. But from then on other countries—particularly the United States and Germany—began to catch up: in 1870 Britain commanded 32 per cent of the world’s manufacturing capacity, but by 1910 it had only 14.7 percent, behind both Germany (15.9 per cent) and the United States (35.3 per cent).
