History of the Jews in Algeria
After Houari Boumediene came to power in 1965, Jews were persecuted in Algeria, facing social and political discrimination and heavy taxes. In 1967-68 the government seized all but one of the country's synagogues and converted them to mosques. By 1969, fewer than 1,000 Jews were still living in Algeria.
