question: With the rapid growth and consolidation of large railroad systems after 1870, union organizations sprang up, covering the entire nation. By 1901, 17 major railway brotherhoods were in operation; they generally worked amicably with management, which recognized their usefulness. Key unions included the Brotherhood of Locomotive Engineers , Brotherhood of Maintenance of Way Division , the Order of Railway Conductors, the Brotherhood of Locomotive Firemen, and the Brotherhood of Railroad Trainmen. Their main goal was building insurance and medical packages for their members, and negotiating bureaucratic work rules that favored their membership, such as seniority and grievance procedures. They were not members of the AFL, and fought off more radical rivals such as the Knights of Labor in the 1880s and the American Railroad Union in the 1890s. They consolidated their power in 1916, after threatening a national strike, by securing the Adamson Act, a federal law that provided 10 hours pay for an eight-hour day. At the end of World War I they promoted nationalization of the railroads, and conducted a national strike in 1919. Both programs failed, and the brotherhoods were largely stagnant in the 1920s. They generally were independent politically, but supported the third party campaign of Robert M. La Follette Sr. in 1924.
Answer this question: How many years after consolidating power did the unions go on strike?
answer: 3

question: Des Vux became stipendiary magistrate and superintendent of rivers and creeks in British Guiana from 1863 to 1869, where he championed native causes. He reorganised and codified old French system of law when he was the Administrator and Colonial Secretary of St. Lucia between 1869 and 1880. Afterwards, Des Vux was appointed Governor of Fiji and High Commissioner Western Pacific from 1880 to 1885. He was appointed Governor of Newfoundland from 1886-1887. Based on his experience in British Guiana where he witnessed many instances of cruel and unjust treatment of indentured servants by plantation owners and managers, des Vux wrote a 10,000-word report in 1869 to Lord Granville, the Secretary of State for the Colonies in which he detailed many abuses. When the contents of the report were published, there was a great outcry and a commission of inquiry was appointed, the Commission of Inquiry into the Treatment of Immigrants. Des Vux gave testimony before the commission in Georgetown and its report led to many improvements in the workers' treatment.

question: The state of Kampuchea , officially Democratic Kampuchea , existed between 1975 and 1979 in present-day Cambodia. The state was controlled by the Khmer Rouge and was founded when KR forces defeated the Khmer Republic of Lon Nol in 1975. Between 1975 and 1979, the state and its ruling Khmer Rouge regime was responsible for the deaths of millions of Cambodians through forced labour and genocide. The KR lost control of most Cambodian territory to Vietnamese occupation. From 1979 to 1982 Democratic Kampuchea survived as a rump state supported by China. In June 1982, the Khmer Rouge formed the Coalition Government of Democratic Kampuchea with two non-communist guerilla factions, which retained international recognition. The state was renamed Cambodia in 1990 in the run up to the UN-sponsored Paris Peace Agreement conference of 1991.
Answer this question: How many years passed in between the renaming of Cambodia and the Paris Peace Agreement conference?
