Which character did you find the most impressive?

I would go with our protagonist Anne. Over the course of the diary, she grows from a spoiled, somewhat naive young girl of thirteen to a self-aware young woman of fifteen. Although she has little political consciousness at the beginning of the diary, she grows to question anti-Semitism and the point of war. During her time in the annex, she suffers from boredom, despair, and the petty persecution of those around her. She also discovers a wealth of good qualities in herself. After the annex residents are discovered, she goes to the concentration camp at Belsen, in Germany, where she dies before her sixteenth birthday.
