Question: When did the first indentured servants came to the country of citizenship of the author of The Everglades: River of Grass?

<P0-S0> the rohingya people have consistently faced human rights abuses by the burmese regime that has refused to acknowledge them as burmese citizens (despite some of them having lived in burma for over three generations)—the rohingya have been denied burmese citizenship since the enactment of a 1982 citizenship law. <P0-S1> the law created three categories of citizenship: citizenship, associate citizenship, and naturalised citizenship. <P0-S2> citizenship is given to those who belong to one of the national races such as kachin, kayah (karenni), karen, chin, burman, mon, rakhine, shan, kaman, or zerbadee. <P0-S3> associate citizenship is given to those who cannot prove their ancestors settled in myanmar before 1823, but can prove they have one grandparent, or pre-1823 ancestor, who was a citizen of another country, as well as people who applied for citizenship in 1948 and qualified then by those laws. <P0-S4> naturalized citizenship is only given to those who have at least one parent with one of these types of burmese citizenship or can provide "conclusive evidence" that their parents entered and resided in burma prior to independence in 1948. the burmese regime has attempted to forcibly expel rohingya and bring in non-rohingyas to replace them—this policy has resulted in the expulsion of approximately half of the 800,000 rohingya from burma, while the rohingya people have been described as "among the world's least wanted" and "one of the world's most persecuted minorities." <P0-S5> but the origin of ‘most persecuted minority’ statement is unclear. <SEP> <P1-S0> the name nigeria was taken from the niger river running through the country. <P1-S1> this name was allegedly coined in the late 19th century by british journalist flora shaw, she was inspired by the name of the river, in preference to terms such as "central sudan". <P1-S2> the origin of the name ''nigeria'' came from the name of the niger river. <P1-S3> the word ( niger )  is an alteration of the tuareg name egerew n-igerewen used by inhabitants along the middle reaches of the river around timbuktu prior to 19th-century european colonialism. <P1-S4> egerew n-igerewen means river of the rivers. <SEP> <P2-S0> Between one - half and two - thirds of white immigrants to the American colonies between the 1630s and American Revolution had come under indentures. <P2-S1> However, while almost half the European immigrants to the Thirteen Colonies were indentured servants, at any one time they were outnumbered by workers who had never been indentured, or whose indenture had expired, and thus free wage labor was the more prevalent for Europeans in the colonies. <P2-S2> Indentured people were numerically important mostly in the region from Virginia north to New Jersey. <P2-S3> Other colonies saw far fewer of them. <P2-S4> The total number of European immigrants to all 13 colonies before 1775 was about 500,000; of these 55,000 were involuntary prisoners. <P2-S5> Of the 450,000 or so European arrivals who came voluntarily, Tomlins estimates that 48% were indentured. <P2-S6> About 75% of these were under the age of 25. <P2-S7> The age of adulthood for men was 24 years (not 21); those over 24 generally came on contracts lasting about 3 years. <P2-S8> Regarding the children who came, Gary Nash reports that ``many of the servants were actually nephews, nieces, cousins and children of friends of emigrating Englishmen, who paid their passage in return for their labor once in America. '' <SEP> <P3-S0> Marjory Stoneman Douglas (April 7, 1890 – May 14, 1998) was an American journalist, author, women's suffrage advocate, and conservationist known for her staunch defense of the Everglades against efforts to drain it and reclaim land for development. <P3-S1> Moving to Miami as a young woman to work for "The Miami Herald", she became a freelance writer, producing over one hundred short stories that were published in popular magazines. <P3-S2> Her most influential work was the book "" (1947), which redefined the popular conception of the Everglades as a treasured river instead of a worthless swamp. <P3-S3> Its impact has been compared to that of Rachel Carson's influential book "Silent Spring" (1962). <P3-S4> Her books, stories, and journalism career brought her influence in Miami, enabling her to advance her causes. <SEP> <P4-S0> The Everglades: River of Grass is a non-fiction book written by Marjory Stoneman Douglas in 1947. <P4-S1> Published the same year as the formal opening of Everglades National Park, the book was a call to attention about the degrading quality of life in the Everglades and remains an influential book on nature conservation as well as a reference for information on South Florida. <P4-S2> It was used as recently as 2007 by "The New York Times".
