What are some distinct factors promoting the revival of minority languages in the face of globalization? (lesser-used minority languages include Welsh, Basque, and Inuktitut)

First Factor

The most important of these factors is nationalism. Even as globalization occurs rapidly (or in some ways because of globalization) minority peoples do not wish to lose their culture. As world cultures become more similar to one another, minority groups feel it is important that they not lose their culture. This is a form of nationalism.

Second Factor

A second factor is growing wealth. As various groups like the Welsh (or various Native American tribes) come to have more wealth, they have the wherewithal to educate their children in their ancestral language. This was not previously possible when children were not able to get much education.

Third Factor

Finally, there is a growing interest in preserving minority cultures even among the majority. Much of the work of ensuring that minority languages come back has been done at least in part by academics from the majority culture. It is often supported by majority governments.
