The Americo-Liberian settlers did not identify with the indigenous peoples they encountered, especially those in communities of the more isolated "bush." They knew nothing of their cultures, languages or animist religion. Encounters with tribal Africans in the bush often developed as violent confrontations. The colonial settlements were raided by the Kru and Grebo people from their inland chiefdoms. Because of feeling set apart and superior by their culture and education to the indigenous peoples, the Americo-Liberians developed as a small elite that held on to political power. It excluded the indigenous tribesmen from birthright citizenship in their own lands until 1904, in a repetition of the United States' treatment of Native Americans. Because of the cultural gap between the groups and assumption of superiority of western culture, the Americo-Liberians envisioned creating a western-style state to which the tribesmen should assimilate. They encouraged religious organizations to set up missions and schools to educate the indigenous peoples.
What did Americo-liberians exclude tribes from?

Rep. Christopher H. Smith (R-NJ), criticized the State Department investigation, saying the investigators were shown "Potemkin Villages" where residents had been intimidated into lying about the family-planning program. Dr. Nafis Sadik, former director of UNFPA said her agency had been pivotal in reversing China's coercive population control methods, but a 2005 report by Amnesty International and a separate report by the United States State Department found that coercive techniques were still regularly employed by the Chinese, casting doubt upon Sadik's statements.
The representative said that inspectors had been show what sort of villages?
Potemkin Villages

One species in particular received widespread attentionthe whooping crane. The species' historical range extended from central Canada South to Mexico, and from Utah to the Atlantic coast. Unregulated hunting and habitat loss contributed to a steady decline in the whooping crane population until, by 1890, it had disappeared from its primary breeding range in the north central United States. It would be another eight years before the first national law regulating wildlife commerce was signed, and another two years before the first version of the endangered species act was passed. The whooping crane population by 1941 was estimated at about only 16 birds still in the wild.
How many years after the noted absence of the whooping crane from its breeding range did the first law regulating wildlife commerce pass
