In the course of the 1848 Revolution King Frederick William IV of Prussia and his Minister Gottfried Ludolf Camphausen had agreed to call for the general election of a national assembly in all Prussian provinces. The Prussian National Assembly however was dismissed by royal decree of 5 December 1848 and the king imposed the Constitution of Prussia. The constitution, though reactionary, at least provided a bicameral parliament, consisting of a First Chamber (Erste Kammer, called House of Lords from 1855), as well as a Second Chamber (Zweite Kammer, from 1855 House of Representatives) whose members were elected according to the three-class franchise system.
