The FRG was a federal republic with power divided between central and regional governments. The Lander or states were represented in the Bundesrat, an upper house in parliament, which could either ask for legislation to be reconsidered or in many cases operate a veto. It's estimated that in the 1970s 50-60% of all legislation was subject to a Bundesrat veto. In addition, the Lander had specific responsibilities, such as the provision of education.
