Realpolitik is a political approach that emphasizes practical and pragmatic solutions over ideological or moral considerations. It focuses on the realities of power and the interests of the state, often prioritizing national interests and security over ethical concerns. This method is commonly associated with leaders who make decisions based on what is effective rather than what is idealistic. Historically, Otto von Bismarck, the German Chancellor, is a key figure in the development of Realpolitik. He skillfully navigated European politics in the 19th century, using diplomacy and strategic alliances to strengthen Germany. His approach illustrates how Realpolitik can lead to significant political outcomes by prioritizing results over principles.
