Hmong Americans (RPA: Hmoob Mes Kas, Pahawh Hmong: 𖬌𖬣𖬵 𖬉𖬲𖬦 𖬗𖬲) are Americans of Hmong ancestry. Many Hmong Americans immigrated to the United States as refugees in the late 1970s, with a second wave in the 1980s and 1990s. Over half of the Hmong population from Laos left the country, or attempted to leave, in 1975, at the culmination of the Laotian Civil War.
During this period, thousands of Hmong were evacuated or escaped on their own to Hmong refugee camps in neighboring Thailand. About 90% of those who made it to refugee camps in Thailand were ultimately resettled in the United States. The rest, about 8 to 10%, resettled in countries including Canada, France, the Netherlands, and Australia.
Pahawh Hmong in the context of Romanized Popular Alphabet
The Romanized Popular Alphabet (RPA) or Hmong RPA (also Roman Popular Alphabet), is a system of romanization for the various dialects of the Hmong language. Created in Laos between 1951 and 1953 by a group of missionaries and Hmong advisers, it has gone on to become the most widespread system for writing the Hmong language in the West. It is also used in Southeast Asia and China alongside other writing systems, most notably Nyiakeng Puachue Hmong and Pahawh Hmong.
