The Bürgerliches Gesetzbuch (German: [ˈbʏʁɡɐlɪçəs ɡəˈzɛtsbuːx] ⓘ, lit. 'Civil Law Book'), abbreviated BGB, is the civil code of Germany, codifying most generally-applicably private law. 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, Korea, the Republic of China (Taiwan), 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.
