How did Henry Morton Stanley help establish the settlement that became Kinshasa?

Sir Henry Morton Stanley played a pivotal role in establishing the settlement that eventually became Kinshasa. During his 1877 exploration of the region, he formed an alliance with the ruler of Kintamo, a local village located on the shores of Malebo Pool.1

Upon returning to the area in 1881 under the auspices of the Association Internationale du Congo, Stanley successfully acquired a site for a trading post. He named this post Léopoldville in honor of his patron, Léopold II, the king of the Belgians. To facilitate development, Stanley also constructed a road from the lower Congo to the site and launched steamers on the upper river to open up trade. The settlement was later renamed Kinshasa in 1966.123
