Problem: The loss of such a large portion of British America, at the time Britain's most populous overseas possession, is seen by some historians as the event defining the transition between the "first" and "second" empires, in which Britain shifted its attention away from the Americas to Asia, the Pacific and later Africa. Adam Smith's Wealth of Nations, published in 1776, had argued that colonies were redundant, and that free trade should replace the old mercantilist policies that had characterised the first period of colonial expansion, dating back to the protectionism of Spain and Portugal. The growth of trade between the newly independent United States and Britain after 1783 seemed to confirm Smith's view that political control was not necessary for economic success.

Problem: The area north of the Congo River came under French sovereignty in 1880 as a result of Pierre de Brazza's treaty with Makoko of the Bateke. This Congo Colony became known first as French Congo, then as Middle Congo in 1903. In 1908, France organized French Equatorial Africa (AEF), comprising Middle Congo, Gabon, Chad, and Oubangui-Chari (the modern Central African Republic). The French designated Brazzaville as the federal capital. Economic development during the first 50 years of colonial rule in Congo centered on natural-resource extraction. The methods were often brutal: construction of the Congo–Ocean Railroad following World War I has been estimated to have cost at least 14,000 lives.
Who brokered a traty with the Makoko people?
The answer is the following:
Pierre de Brazza
