To determine whether the characteristics describe conditions in Germany before or after unification, we can categorize them as follows:
Before Unification:
- 300 German states
- Risk of French aggression
- Boundaries changed by Napoleon
After Unification:
- Written constitution
- Trade facilitated in the region
- Two-house legislature
This categorization reflects the political, economic, and territorial changes that occurred in Germany around the time of unification in 1871. Before unification, Germany was fragmented into many states and experienced external threats, while after unification, it adopted a more centralized government structure and improved trade conditions.
