This 1951 book is the history of an idea. The unique concept of dominion status within a Commonwealth of Nations is the result of the need for freedom combined with peace, for independence combined with international obligations, for common action without central control. The attainment has come out of many conflicting forces which can only be studied historically. This book tells the experiences of the different nations of the Commonwealth, to explain how past events have led them into this unprecedented form of association. The British Commonwealth exemplifies a way in which independent and self-governing nations may live together, and also how nations that are somewhat politically, socially, or economically undeveloped may be partnered by those who have advanced a little further along the road to civilized society. Attention is also given to the dependent colonial Empire, particularly to those countries already within sight of full Dominion status.
