India is a different matter. That was a place, of course, with a massive population. It was an important market for exports, but it was in a different league from the white dominions, and both were in a quite different position from what were strictly speaking called the colonies. It is very important to remember that before the 1940s — that is to say, in the great age of empire — trade with foreign countries was greater than with “British” countries, to use the language of the time.
Liberals pointed this out again and again. They argued that the great glory of the British economy was not the empire but rather free trade. That meant trading with everybody and in practice trading a very great deal with Europe. That was where British bacon, British eggs, British iron ore, or British timber came from, and much else besides. Before the 1940s, the UK was a profoundly European economy, deeply integrated into trade and production within the European continent.
