In 1996 the Council of Europe adopted this Recommendation on Yiddish culture, recognising its status as an endangered minority language in Europe and proposing several measures to protect Yiddish culture.
See also this report of the Committee on Culture and Education by Emanuelis Zingeris which formed the basis of the recommendation. The report has an elaborate addendum on the Colloquy on Yiddish Culture that took place from 3-5 May 1995 in Vilnius, Lithuania.
Some countries have also accorded Yiddish the status of official minority language, for instance Sweden.
