The Bürgerliches Gesetzbuch (German: [ˈbʏʁɡɐlɪçəs ɡəˈzɛtsbuːx], lit.: 'Civil Law Book'), abbreviated BGB, is the civil code of Germany. In development since 1881, it became effective on 1 January 1900, and was considered a massive and groundbreaking project.
The BGB served as a template in several other civil law jurisdictions, including Japan, South Korea, the Republic of China, the People's Republic of China, Thailand, Brazil, Greece, Estonia, Latvia and Ukraine. It also had a major influence on the 1907 Swiss civil code, the 1942 Italian civil code, the 1966 Portuguese civil code, and the 1992 reformed Dutch civil code.
