Underground education, or clandestine education, refers to various practices of teaching carried out at times and places where such educational activities were deemed illegal.
Examples of places where widespread clandestine education practices took place included education of Blacks during the slave period in the USA and the Secret Teaching Organization in Poland under the Nazis.
There is a Greek - mostly oral - tradition claiming that secret schools (Krifo scholio) operated during the Ottoman period. There is scant written evidence for this and many historians view it as a national myth. Others believe that the Greek secret school is a legend with a core of truth. According to certain sources, secret schools for Albanians operated in late 19th century by Albanian-speaking communities and Bektashi priests or nationalists under Ottoman rule.
In Lithuania, clandestine schools (Slaptoji mokykla) operated almost in every village, at the end of 19th and beginning of 20th century, because of the suppression of Lithuanian language by the tsarist Russian government.
Secret schooling was organized in Jewish Ghettos during the Nazi regime and the German occupation in Europe. During the Taliban rule in various parts of Afghanistan (late 20th, early 21st c.), secret schools operated, mostly for women and girls. In the 1930s and 1940s, the authoritarian nationalistic regime of Brazil took anti-immigrant measures, especially against the Japanese. Japanese and other foreign schools, languages and printed material were restricted, and a compulsory assimilation program was instituted. Japanese schools became illegal in 1938. During that period, Japanese immigrants established secret schools and a newspaper in Japanese was printed.
