Traveling from the Atlantic Ocean coast in present-day Gabon via the rivers Ogooué and Lefini he arrived in 1880 in the kingdom of the Téké where on 10 September 1880 he signed the treaty with king Makoko establishing French control over the region and making his capital soon afterwards at the small village named Mfoa later to be called Brazzaville. Establishing control Establishing French control was difficult. Belgian King Leopold II also tried to gain a foothold on the northern bank of the Congo River and sent Stanley to the area around Brazzaville. Following this was a series of revolts against the French of which the Bahangala Revolt led by Mabiala Ma Nganga was the first important one. It started in 1892 with the murder of the French administrator Laval and ended with the killing by the French of its leader in 1896. Many of the revolts were the result of French policy of maltreating the local population through the use of harsh forced labor. The locals were governed through the use of the repressive Code de l'indigénat Act. A law, which introduced forced labor, made it illegal for the local population to publicly air its grievances and excluded them from all the important jobs.The French government allowed for the establishment of the so-called Concessionary Companies in 1889 so as to circumvent the economic non-discrimination provisions of the Treaty of Berlin and maximize the revenue drawn from underpopulated and undeveloped regions under their control. Roughly forty companies with a capital of roughly 59.5 million francs were given a free hand to exploit the colony's resources under virtual monopoly conditions. 650,000 square miles of land, except for a few strategic locations mainly around the Congo River, were leased as concessions for a thirty-year period. Cost-benefit considerations reigned supreme as often undercapitalized companies employed unqualified personnel and/or adventurers who lived off the land while stripping their concessions of all possible riches. Ivory and rubber virtually disappeared from the concessionary areas; indigenous populations were decimated by brutal forced labor, disease, and maladministration, and some fled to neighboring colonies. French rule was brutal and led to many thousands of deaths. The construction between 1921 and 1934 of the 511 km long railway, the Chemin de Fer Congo-Océan between Brazzaville and Pointe-Noire is for
