Corporate power comprises a set of economic-financial, labor, social, political, institutional, environmental, and cultural aspects, which together secure quasi-monopoly power for the companies. The European world-economy came into existence in the "long sixteenth century". In the early fifteenth century, the Venetian Republic constructed an empire in the Aegean Sea, becoming a pioneer state of commercial capitalism. In 1770-1880 period, England/Great Britain was the most advanced country in the world-economy. Great Britain had a strong international hegemonic role, which gave corporate power to its companies as a whole. After the First World War, the United States became the financier and supplier of weaponry and equipment of both Great Britain and France, and replaced them in areas they had previously dominated. In the United States, the previous accelerated growth of production and demand created an important surplus of domestic savings.
