Fascist politicians become popular in Europe after World War I because of the increasing loss of self esteem and devastation of the world war.
Explanation:
The people of European countries were reeling from the massive shock of disasters in the first world war and felt a need for a strong and charismatic leader who can draw them out of their troubles and then make their country a better place.
The distressed population fell for many authoritarian leaders due to this reason as it was seen that the leaders will be able to bring the country out of the horrors that the world war had brought on them.
