Under the impact of the bourgeois revolutionary trend, liberal parliamentarians in various German states targeted the feudal aristocracy and royal power. Prussia, as a large state, also faced challenges. William IV was unwilling to give up his hypocritical democracy and image of a "virtuous king", and he adopted a cold approach to these challenges. As a feudal aristocratic manor owner, Bismarck hated the bourgeoisie for targeting their own interests. In June 1848, he recruited a group of influential manor owners to jointly sign a letter to the king: "I will never agree to any confiscation of private property." Territory demands, if such injustice occurs, we call for decisive action."

Bismarck did not wait, he began to pay attention to political life with great enthusiasm, and he once traveled to Berlin, Potsdam, etc. In some cities, I have made a large number of friends in the political circles. In 1851, the Confederation Assembly in Frankfurt was re-established, and Prussia needed to send a spokesman with firm character and diplomatic skills to Frankfurt. Gerlach once again seized this opportunity and recommended Bismarck to the king: "Your Majesty, his loyalty and courage have proven that his eloquence and pragmatic attitude towards things are enough for this mission." William IV repeatedly said After hesitation, I finally agreed to the recommendation.

In Frankfurt’s diplomatic circle, the Austrian representative, Count Thun, always likes to assume the domineering posture of the Great Austrian Empire among envoys from various countries, and always reveals on some occasions that Austria is the leader of the German Alliance. emotions. Although Bismarck appeared as the minister of one of the two strongest German states, Thun still did not take him seriously. Bismarck was very dissatisfied with the Federal Parliament being hosted by Austria. He believed that this situation would not improve Prussia's diplomatic situation. He pessimistically wrote to Foreign Minister Manteuffel: "I have no doubts about the outcome of the Federal Parliament. There is no hope for Prussia."

In 1854, Prussia and Austria reached an agreement to extend the treaty of mutual defense alliance between the two countries for another three years. Bismarck suggested to the king and the foreign minister, "We should station the army in Silesia. Once the situation requires, the army can quickly cross the border into Austria and use strength to take back the status of 'German Arbiter' from Austria."

William IV rejected Bismarck's suggestion to invite Napoleon III. He accused "this is risky diplomacy." Bismarck was once again left out in the cold, and there was unspeakable pain and trouble buried in his heart. Bismarck once again bet on the wrong chips during his official career. He was fully focused around King William IV, political confidant Gerlach and Foreign Minister Manteuffel. He did not give up his loyalty and efforts even after being ignored by the king many times.
