Islam is the second largest religion in Belgium after Christianity. The exact number of Muslims in Belgium is unknown but various sources estimate that 4.0% to 7.6% of the country's population adheres to Islam. The first registered presence of Islam in Belgium was in 1829, but most Belgian Muslims are first-, second-, or third-generation immigrants that arrived after the 1960s.
