The term, "informal empire" is most commonly associated with the
British Empire, where it is used to describe the extensive reach of British interests into regions and nations which were not formal parts of the Empire, in that they were not
colonies and were not directly administered by the British government. Among the most notable elements of the British informal empire was the trade relationship it maintained with
China, along with British commercial interests and investments in
South America. The informal empire consisted primarily of three elements:
extraterritoriality, a trade system that heavily favored the Western powers, and interventionist tools such as military force and the informal power exerted by diplomats. In China, the most significant source of informal control was the
Shanghai Municipal Council, which although theoretically under lease from the Chinese government, was effectively unaccountable to them and saw most positions filled by Britons backed by British diplomatic influence. Several
unequal treaties were signed between China and
Western powers, and concessions were established in Chinese port cities, such as the
Shanghai International Settlement.
Imperial financial presence was established through war indemnities in the aftermath of various Sino-foreign wars, legally immune foreign banks with government links and near-oligopoly in China, seizure of Chinese government revenues, loan agreements stipulating cession of profits, government revenues, mining rights, foreign engineering or administrative control, and above-market-price supply contracts. This system broke down after the fragmentation of China by
the era of the Warlords in 1916 and the First World War, causing most Western powers (with the notable exception of
Japan which attempted to expand direct control) to be unable to effectively enforce their privileges in mainland China. Challenges to British informal control in China from other European powers, as well as the United States, led to a shift from more informal to more formal control at the turn of the century, with the establishment of more concessions and the assumption of greater control of the Chinese economy. These were returned during the Second World War so that China would continue resisting Japan. Black claimed that the British military intervention in the
Russian Civil War on behalf of the
White Army was motivated in part by a desire to establish an informal empire of political influence and economic ties in Southern Russia, to deny
Germany access to these assets and block their passage to British colonies in Asia. Informal empire, like many imperial relationships, is difficult to classify and reduce to a prescriptive definition. In the instance of the British informal empire, the character of the relationship varied widely. The Chinese intensely opposed any foreign control over China or its economy, and both the
First and
Second Opium Wars were fought between China and several Western powers, resulting in Chinese defeat and the increase of both formal and informal foreign power. South American governments were often willing partners in the extension of British commercial influence, but military action was sometimes taken against those who tried to apply
protectionist policies. Informal empire is an important concept required to adequately explain the reach and influence of empire, and in the case of the British Empire, is vital to any holistic account of the British imperial experience and intrinsic to describing the interests and purposes of the Empire as a whole. Informal empire, far from being distinctive and separate from formal empire, is often bound up with formal imperial interests. For example, the British informal empire in China was a product of
Company rule in India, as the East India Company used its Indian territories to grow opium, which was then
shipped to Chinese ports. By 1850, the Chinese opium trade accounted for up to 20% of the revenue of the entire British Empire, serving as the most profitable single commodity trade of the 19th century. As Timothy Brook and Bob Wakabayashi write of opium trade, "The British Empire could not survive were it deprived of its most important source of capital, the substance that could turn any other commodity into silver." In the economic sphere, the British informal empire was driven by the
free trade economic system of the Empire. In the so-called "
Imperialism of Free Trade" thesis, as articulated by historians
Ronald Robinson and
John "Jack" Gallagher, the British Empire expanded as much by the growth of informal empire as it did by acquiring formal dominion over colonies. Furthermore, British investment in empire was to be found not only in the formal Empire, but also in the informal empire – and, by Robinson and Gallagher's account, was indeed predominantly located in the informal empire. It is estimated that between 1815 and 1880, £1,187,000,000 in credit had accumulated abroad, but no more than one-sixth was placed in the formal empire. Even by 1913, less than half of the £3,975,000,000 of foreign investment lay inside the formal Empire. British historian
David Reynolds has claimed that during the process of
decolonisation, it was hoped that as an alternative to the declining formal empire, informal influence, marked by economic ties and defense treaties would hold sway over the former colonies. Reynolds suggested that the establishment of the
Commonwealth was an attempt to maintain some form of indirect influence over the newly independent countries. ==United States==
