Throughout much of the 20th century, the communist government repressed religious practices. It targeted the clergy of the Mongolian Buddhist Church, which had been tightly intertwined with the previous feudal government structures (e.g. from 1911 on, the head of the Church had also been the Khan of the country). In the late 1930s, the regime, then led by Khorloogiin Choibalsan, closed almost all of Mongolia's over 700 Buddhist monasteries and killed at least 30,000 people, of whom 18,000 were lamas. The number of Buddhist monks dropped from 100,000 in 1924 to 110 in 1990.
