The American Revolution had not been provoked by oppression, violence, and massacre. The 'chains and slavery' of revolutionary orators was only a figure of speech. The real causes were constitutional and personal; and the actual crux of the question was one of payment for defence. Of course there were many other causes at work. The social, religious, and political grudges with which so many emigrants had left the mother country had not been forgotten and were now revived. Commercial restrictions, however well they agreed with the spirit of the age, were galling to such keen traders. And the mere difference between colonies and motherland had produced misunderstandings on both sides. But the main provocative cause was Imperial taxation for local defence. The Thirteen Colonies could not have held their own by land or sea, much less could they have conquered their French rivals, without the Imperial forces, which, indeed, had done by far the greater part of the fighting. How was the cost to be shared between the mother country and themselves? The colonies had not been asked to pay more than their share. The point was whether they could be taxed at all by the Imperial government when they had no representation in the Imperial parliament. The government said Yes. The colonies and the opposition at home said No. As the colonies would not pay of their own accord, and as the government did not see why they should be parasites on the armed strength of the mother country, parliament proceeded to tax them. They then refused to pay under compulsion; and a complete deadlock ensued.
