Step 1: Nationalism in France during 1789
The first significant impression of nationalism in France during 1789 was the French Revolution. The revolution began as a struggle for liberty, equality, and fraternity, which led to the emergence of nationalism in France and its spread across Europe.
Step 2: Why the other options are incorrect
- (B) Rise of Napoleon: While Napoleon played a significant role in shaping European nationalism, it was not the first impression of nationalism in France. The French Revolution preceded Napoleon's rise.
- (C) Unification of Germany: This occurred much later, in the mid-19th century, and is unrelated to the early rise of nationalism in France.
- (D) Beginning of Absolute Monarchy: This is not an expression of nationalism, but rather an autocratic rule.
Thus, the correct answer is option (A) French Revolution.
