In many countries, concerted attempts are being made to preserve traditions that are at risk of being lost. A number of factors can exacerbate the loss of tradition, including industrialization, globalization, and the assimilation or marginalization of specific cultural groups. Customary celebrations and lifestyles are among the traditions that are sought to be preserved. Likewise, the concept of tradition has been used to defend the preservation and reintroduction of minority languages such as Cornish under the auspices of the European Charter for Regional or Minority Languages. Specifically, the charter holds that these languages "contribute to the maintenance and development of Europe's cultural wealth and traditions". The Charter goes on to call for "the use or adoption... of traditional and correct forms of place-names in regional or minority languages". Similarly, UNESCO includes both "oral tradition" and "traditional manifestations" in its definition of a country's cultural properties and heritage. It therefore works to preserve tradition in countries such as Brazil.
