What effect did British have on the slave trade during the age of new imperialism

Imperialism did not begin in the nineteenth century. From the sixteenth to the early nineteenth century, an era dominated by what is now termed Old Imperialism, European nations sought trade routes with the Far East, explored the New World, and established settlements in North and South America as well as in Southeast Asia. They set up trading posts and gained footholds on the coasts of Africa and China, and worked closely with the local rulers to ensure the protection of European economic interests. Their influence, however, was limited. In the Age of New Imperialism that began in the 1870s, European states established vast empires mainly in Africa, but also in Asia and the Middle East. Unlike the sixteenth - and seventeenth-century method of establishing settlements, the new imperialists set up the administration of the native areas for the benefit of the colonial power. European nations pursued an aggressive expansion policy that was motivated by economic needs that were created by the Industrial Revolution. Between 1870 and 1914, Europe went through a "Second Industrial Revolution," which quickened the pace of change as science, technology, and industry spurred economic growth. Improvements in steel production revolutionized shipbuilding and transportation. The development of the railroad, the internal combustion engine, and electrical power generation contributed to the growing industrial economies of Europe and their need to seek new avenues of expansion
