The Tremembé were dispossessed of most their remaining lands in the aftermath of the 1854 "Lei da Terra" (land tenure decree) of the Empire of Brazil. The state governor of Ceará issued a decree in 1863 declaring the Tremembé an extinct people, remaining Indians officially regarded as caboclos (mixed-race) or "descendents" of Indians, but not an existing ethnicity. Nonetheless, the Tremembé resurged and received recognition from the Fundação Nacional do Índio in the 1980s. The original language of the Tremembé is extinct. Current members of the ethnicity speak Portuguese as their mother tongue. The language is unclassified, but generally believed to have "not" been part of the Tupi–Guarani family (thus, "Tapuia", or non-Tupi). Nonetheless, the Tremembé may have borrowed a considerable number of Tupi words through interaction with their Tupi neighbors.   2011 Beijing International Challenger  The 2011 Beijing International Challenger was a professional tennis tournament played on hard courts.
