Yes, you are right! Because it depends on the historical context, war or peace, poor or rich, and the year I talk about the historical situation, the leaders, history is not good or bad; it is events that determine history. The same leader can exist but in a different situation can do different things or does not exist for different events. I already gave an example, Hitler without the 1929 crisis would have been an obscure Bavarian agitator, but millions of desperate unemployed people slid towards extremism. That's why I have always been against fixed leaders because they do not represent the change of era.
