The 146 Articles of the Basic Law supersede all other German legal norms and define the basic systems and values of the state. National Holiday 3 October The Basic Law states that the colours of the federal flag shall be black, red, and gold. In 1949, this followed on from the flag of the first German republic of 1919.
