Which was a major reason for Europes colonial expansion during the period 1450 to 1750?

The global expansion of western Europe between the 1760s and the 1870s differed in several important ways from the expansionism and colonialism of previous centuries. Along with the rise of the Industrial Revolution, which economic historians generally trace to the 1760s, and the continuing spread of industrialization in the empire-building countries came a shift in the strategy of trade with the colonial world. Instead of being primarily buyers of colonial products (and frequently under strain to offer sufficient salable goods to balance the exchange), as in the past, the industrializing nations increasingly became sellers in search of markets for the growing volume of their machine-produced goods. Furthermore, over the years there occurred a decided shift in the composition of demand for goods produced in the colonial areas. Spices, sugar, and slaves became relatively less important with the advance of industrialization, concomitant with a rising demand for raw materials for industry (e.g., cotton, wool, vegetable oils, jute, dyestuffs) and food for the swelling industrial areas (wheat, tea, coffee, cocoa, meat, butter).

This shift in trading patterns entailed in the long run changes in colonial policy and practice as well as in the nature of colonial acquisitions. The urgency to create markets and the incessant pressure for new materials and food were eventually reflected in colonial practices, which sought to adapt the colonial areas to the new priorities of the industrializing nations. Such adaptation involved major disruptions of existing social systems over wide areas of the globe. Before the impact of the Industrial Revolution, European activities in the rest of the world were largely confined to: (1) occupying areas that supplied precious metals, slaves, and tropical products then in large demand; (2) establishing white-settler colonies along the coast of North America; and (3) setting up trading posts and forts and applying superior military strength to achieve the transfer to European merchants of as much existing world trade as was feasible. However disruptive these changes may have been to the societies of Africa, South America, and the isolated plantation and white-settler colonies, the social systems over most of the Earth outside Europe nevertheless remained much the same as they had been for centuries (in some places for millennia). These societies, with their largely self-sufficient small communities based on subsistence agriculture and home industry, provided poor markets for the mass-produced goods flowing from the factories of the technologically advancing countries; nor were the existing social systems flexible enough to introduce and rapidly expand the commercial agriculture (and, later, mineral extraction) required to supply the food and raw material needs of the empire builders.

The adaptation of the nonindustrialized parts of the world to become more profitable adjuncts of the industrializing nations embraced, among other things: (1) overhaul of existing land and property arrangements, including the introduction of private property in land where it did not previously exist, as well as the expropriation of land for use by white settlers or for plantation agriculture; (2) creation of a labour supply for commercial agriculture and mining by means of direct forced labour and indirect measures aimed at generating a body of wage-seeking labourers; (3) spread of the use of money and exchange of commodities by imposing money payments for taxes and land rent and by inducing a decline of home industry; and (4) where the precolonial society already had a developed industry, curtailment of production and exports by native producers.

The classic illustration of this last policy is found in India. For centuries India had been an exporter of cotton goods, to such an extent that Great Britain for a long period imposed stiff tariff duties to protect its domestic manufacturers from Indian competition. Yet, by the middle of the 19th century, India was receiving one-fourth of all British exports of cotton piece goods and had lost its own export markets.

Clearly, such significant transformations could not get very far in the absence of appropriate political changes, such as the development of a sufficiently cooperative local elite, effective administrative techniques, and peace-keeping instruments that would assure social stability and environments conducive to the radical social changes imposed by a foreign power. Consistent with these purposes was the installation of new, or amendments of old, legal systems that would facilitate the operation of a money, business, and private land economy. Tying it all together was the imposition of the culture and language of the dominant power.

The changing nature of the relations between centres of empire and their colonies, under the impact of the unfolding Industrial Revolution, was also reflected in new trends in colonial acquisitions. While in preceding centuries colonies, trading posts, and settlements were in the main, except for South America, located along the coastline or on smaller islands, the expansions of the late 18th century and especially of the 19th century were distinguished by the spread of the colonizing powers, or of their emigrants, into the interior of continents. Such continental extensions, in general, took one of two forms, or some combination of the two: (1) the removal of the indigenous peoples by killing them off or forcing them into specially reserved areas, thus providing room for settlers from western Europe who then developed the agriculture and industry of these lands under the social system imported from the mother countries, or (2) the conquest of the indigenous peoples and the transformation of their existing societies to suit the changing needs of the more powerful militarily and technically advanced nations.

At the heart of Western expansionism was the growing disparity in technologies between those of the leading European nations and those of the rest of the world. Differences between the level of technology in Europe and some of the regions on other continents were not especially great in the early part of the 18th century. In fact, some of the crucial technical knowledge used in Europe at that time came originally from Asia. During the 18th century, however, and at an accelerating pace in the 19th and 20th centuries, the gap between the technologically advanced countries and technologically backward regions kept on increasing despite the diffusion of modern technology by the colonial powers. The most important aspect of this disparity was the technical superiority of Western armaments, for this superiority enabled the West to impose its will on the much larger colonial populations. Advances in communication and transportation, notably railroads, also became important tools for consolidating foreign rule over extensive territories. And along with the enormous technical superiority and the colonizing experience itself came important psychological instruments of minority rule by foreigners: racism and arrogance on the part of the colonizers and a resulting spirit of inferiority among the colonized.

Naturally, the above description and summary telescope events that transpired over many decades and the incidence of the changes varied from territory to territory and from time to time, influenced by the special conditions in each area, by what took place in the process of conquest, by the circumstances at the time when economic exploitation of the possessions became desirable and feasible, and by the varying political considerations of the several occupying powers. Moreover, it should be emphasized that expansion policies and practices, while far from haphazard, were rarely the result of long-range and integrated planning. The drive for expansion was persistent, as were the pressures to get the greatest advantage possible out of the resulting opportunities. But the expansions arose in the midst of intense rivalry among major powers that were concerned with the distribution of power on the continent of Europe itself as well as with ownership of overseas territories. Thus, the issues of national power, national wealth, and military strength shifted more and more to the world stage as commerce and territorial acquisitions spread over larger segments of the globe. In fact, colonies were themselves often levers of military power—sources of military supplies and of military manpower and bases for navies and merchant marines. What appears, then, in tracing the concrete course of empire is an intertwining of the struggle for hegemony between competing national powers, the manoeuvring for preponderance of military strength, and the search for greatest advantage practically obtainable from the world’s resources.
