"MdB" stands for "Mitglied des Bundestages," which translates to "Member of the Bundestag" in English. The Bundestag is the federal parliament of Germany, responsible for making laws and representing the interests of the German people. Members are elected every four years and play a crucial role in the legislative process. Each MdB represents a specific constituency and is part of a political party. They participate in debates, propose legislation, and serve on committees that focus on various issues, such as healthcare, education, and foreign policy. Their work is essential for the functioning of Germany's democratic system.
