Another important historical instance of entrenched clause in a constitution was enshrined in the Basic Law for the Federal Republic of Germany of 1949, in reaction to development of 1919–1945. Firstly, it states that the Basic Law can only be changed by a statute that explicitly modifies or amends the wording of the Basic Law. Secondly, it contains a provision, which sets the substantive core beyond the reach of powers of the constitution-maker. This is called imperative of unchangeability or eternity clause. Unlike its Czech counterpart, the eternity clause ("Ewigkeitsklausul") of the German Basic Law does specify, what its substantive core is: the subdivision of the federation into states, the states' powers in lawmaking, the dignity of a human, the principles of a democratic social state, the sovereignty of the people, the division of powers, the limitation of government by law, and the right to resist.
