England's colonial system had been developed into a great empire.
Principles of English liberty and representative government were carried

self-governing communities. Thus the separate colonies in Canada, in
Australia, and in South Africa were grouped in each case into a federal
government, somewhat similar to that of the United States, and three
great British democracies were formed within the boundaries of the
empire. So successful has been the British system of colonial government
that there has been virtually no question of loyalty during the Great
War. All parts of the dominions have contributed in men and money to the
common cause, and frequent imperial war conferences have been held in
London. In these conferences representatives from the colonies and the
mother country have joined in the discussion of important imperial
questions.
