The idea
Prussia’s success in unifying Germany rested on several interlocking reasons. Bismarck’s role was central: his diplomacy isolated Austria and France, and his willingness to use war served Prussian interests. Military strength mattered: reforms and efficient organisation gave Prussia battlefield advantages. Economic factors were also important: the Zollverein and industrial growth tied German states to Prussia and funded its army. German nationalism provided popular pressure for unity, though it was often used by Prussia rather than controlled by it. The international situation helped: rival powers were distracted or neutral, allowing Prussia to act without a major coalition against it. Together, these reasons explain why Prussia, not Austria, led the Klein-deutschland solution by 1871.

Common mistakes and how to put them right
Treating Bismarck as the only reason for success.
Put it right: Explain how military, economic, nationalist and international factors also contributed.
Assuming German nationalism was always controlled by Bismarck.
Put it right: Recognise popular nationalist pressure as a factor that Prussia could use but not fully control.
Ignoring the international situation.
Put it right: Explain how the attitudes of other powers allowed Prussia to act.
Exam tips
- Organise your answer around the named reasons, but show how they connected to each other.
- Use specific examples, such as the Zollverein, army reforms, or diplomatic isolation of Austria and France.
- Explain why each reason mattered for Prussia’s success, not just what happened.
