At the opening of the twentieth century, Britain's influence in Argentina was at its peak and resembled, in certain ways, its position in countries such as Australia and Canada. Yet, in the following generation, British preeminence was persistently threatened, and Argentina's prospects plunged into a seemingly irreversible decline. Why did the Anglo-Argentine connection, which appeared so mutually beneficial in 1900, become strained to the breaking point by 1939? This book shows that Britain's efforts in Argentina were usually more pathetic than imperialistic, but that in periods of difficulty (1914 to 1918, and in the 1930s), British pressure unwittingly helped into power a political party that brought destruction, not merely to British interests, but also to the Argentine Republic's future promise.
