Final answer:
Bismarck's foreign policy after German unification was a classic example of Realpolitik. He prioritized pragmatic, calculated actions to expand and secure German power, avoiding unnecessary aggression and implementing social reforms to maintain stability.
Step-by-step explanation:
After German unification, Otto von Bismarck's foreign policy actions were emblematic of Realpolitik, a term reflecting his pragmatic approach to politics based on practical objectives rather than moral or ideological considerations. Through calculated wars with Denmark, Austria, and France, Bismarck expanded German power, but he did so with a clear vision that avoided excessive aggression, such as opting not to occupy Austria, to prevent future instability. Realpolitik was evident in his domestic policies too, as he implemented social reforms to counter the appeal of socialism, despite his conservative stance against such reforms.Bismarck also strategically used international diplomacy to safeguard the newly formed German Empire. His coldly calculating maneuvers were aimed at consolidating power and avoiding unnecessary conflict by maintaining alliances only as long as they served his own country's interests. This approach to foreign policy ensured that Germany rapidly rose as an industrial and military powerhouse, shifting the balance of power in Europe and setting the stage for future international dynamics leading up to World War I.
