For a long time the department was the only channel of communication between the people and the government. It used to be headed by the
Registrar General, who was also called the 'Protector of the Chinese'.
Fung-Chi Au (; 1847–1914), who was the teacher of Chinese literature for
Sun Yat-sen, was the Secretary of the Department of Chinese Affairs (). In 1913 the department was called the Secretariat for Chinese Affairs. After the
1967 riots, the colonial government introduced the City District Officer Scheme (民政主任) "as the first sign of reaching out to the ordinary people" in Hong Kong society. It was renamed the Home Affairs Department in 1971 because, according to the government, the department dealt not only with matters relating to the Chinese. The first
Secretary for Home Affairs was
Donald Luddington. In February 2021, the Home Affairs Department announced that pro-democracy district council members would be excluded from government-linked organizations that focus on neighborhood issues. In March 2021,
Ramon Yuen said that officials from the department had selectively trimmed his discussion about a
pro-democracy protest from the official record. ==Area committees==
