For some months after Ben Ali's overthrow in the 2010–2011 Tunisian Revolution, many of the imams his regime had appointed were replaced, "often by violent Islamists", accused of having collaborated with the old regime. By October 2011, the Ministry of Religious Affairs announced that it had lost control of about 400 mosques. (Another indication of the ascendance of conservative Islam was the large plurality the Islamist Ennahda party won in the 2011 Constituent Assembly election.)
