After being deposed in 1965, Ben Bella was sent to an underground prison where he was detained for eight months. After that, he was transferred to an isolated villa in Birouta, where he was placed under house arrest for 14 years. However, he was permitted a private life there, and in 1971 he married Zhora Sellami, an Algerian Journalist. Their meeting, was arranged by Ben Bella’s mother. They became religiously observant Muslims, and adopted two girls, Mehdia and Nouria. After Boumedienne's death in 1978, restrictions on him were eased in July 1979, and he was freed on 30 October 1980. Ben Bella briefly resided in France, but was expelled in 1983. He then moved to Lausanne, Switzerland, and launched the Mouvement pour la Démocratie en Algérie (MDA), a moderate Islamic opposition party, in 1984. In September 1990, he returned to Algeria, and in 1991 led the MDA in the first round of the country's abortive parliamentary elections. The MDA was banned in 1997.
