people. Casement travelled for weeks in the upper Congo Basin to interview people throughout the region, including workers, overseers and mercenaries. He delivered a long, detailed eyewitness report to the Crown that exposed abuses: "the enslavement, mutilation, and torture of natives on the rubber plantations." It became known as the Casement Report of 1904. King Leopold had held the Congo Free State since 1885, when the Berlin Conference of European powers and the United States effectively gave him free rein in the area. Leopold had exploited the territory's natural resources (mostly rubber) as a private entrepreneur, not as king of the Belgians. Using violence and murder against men and their families, Leopold's private Force Publique had decimated many native villages in the course of forcing the men to gather rubber and abusing them to increase productivity. Casement's report provoked controversy, and some companies with a business interest in the Congo rejected its findings, as did Casement's former boss, Alfred Lewis Jones. When the report was made public, opponents of Congolese conditions formed interest groups, such as the Congo Reform Association, founded by E. D. Morel with Casement's support, and demanded action to relieve the situation of the Congolese. Other European nations followed suit, as did the United States. The British Parliament demanded a meeting of the 14 signatory powers to review the 1885 Berlin Agreement defining interests in Africa. The Belgian Parliament, pushed by Socialist leader Emile Vandervelde and other critics of the king's Congolese policy, forced Léopold to set up an independent commission of inquiry. In 1905, despite Léopold's efforts, it confirmed the essentials of Casement's report. On 15 November 1908, the parliament of Belgium took over the Congo Free State from Léopold and organised its administration as the Belgian Congo. Peru: Abuses against the Putumayo Indians In 1906 the Foreign Office sent Casement to Brazil: first as consul in Santos, then transferred to Pará, and lastly promoted to consul-general in Rio de Janeiro. He was attached as a consular representative to a commission investigating rubber slavery by the Peruvian Amazon Company (PAC), which had been registered in Britain in 1908 and had a British board of directors and numerous stockholders. In September 1909, a journalist named Sidney Paternoster wrote in Truth, a British magazine, of abuses against PAC workers and competing Colombians in the disputed region of the Peruvian Amazon. In addition, the British consul at Iquitos had
