Endangered Cultures (Languages)

Hawaiian
The Hawai'i was one of the world's most literate societies with over 90 percent of the population able to read and write. The language and culture was almost destroyed as a result of Hawaii's annexation to the United States in the early 20th century.

Kalmyk

The republic of Kalmykia lies in Russia, at the southeastern corner of Europe. It is home to the continent's only Buddhist indigenous people, the Kalmyks, who speak an endangered Mongolic language. The language, hence culture almost died in the hands of Stalin but miraculously survived and persevered.

Koro

Is an endangered Tibeto-Burman language spoken in Arunachal Pradesh, India with an estimated 800 to 1000 speakers. Until recently, Koro was a hidden language, not acknowledged in scientific literature or by local and national political structures as a distinct language. After immigrating out of Tibet, the community broke off and disintegrated.

Quechua

Quechua was the unifying language of the Inca Empire. Though Quechua is the indigenous language for many groups in the Andes, it is being displaced by today's dominant language (Colony): Spanish.

Isthmus Zapotec

The Zapotec Language family of Oaxaca and Vercruz, Mexico comprises a large number of distinct indigenous languages that can be traced very far back. Historically, government teachers discouraged use of the Zapotec language further quickening the extinction process.
