Final answer:
Frederick William I was known for creating a powerful army and efficient administration in Prussia. His successor, Wilhelm I, along with Otto von Bismarck, led to the unification of Germany and the establishment of the German Empire, with Wilhelm I as its first Emperor
Step-by-step explanation:
Frederick William I, often referred to as the “Soldier King,” was known for his efficient, centralized administration, fostering a well-disciplined civil service, and especially for creating a strong, well-trained standing army that formed the backbone of what became one of the most formidable military powers in Europe. Next in line was his son, Wilhelm I, under whose rule major accomplishments included the appointment of Otto von Bismarck as prime minister. Bismarck, embracing Realpolitik, strengthened Prussia through wars, outmaneuvered Austria in the politics of unification, and excluded it from German affairs, acquired regions from Denmark and France, and strategically led to the creation of a unified Germany, crowning Wilhelm I as the German Emperor in 1871.
Otto von Bismarck's tenure as prime minister paved the way for the formation of a unified Germany. His diplomatic and military strategies were crucial in achieving German national unity and the establishment of the German Empire. By persuading Wilhelm I not to occupy Austria, facilitating the creation of a customs union among German states, and involving Prussia in a series of decisive wars, Bismarck positioned Prussia at the center of German affairs and Wilhelm I as the head of the new empire.
