The period after World War I in Europe was a charismatic situation, Xavier Marquez explains, when a number of people made charismatic claims more or less successfully:
The most famous of these people was Hitler, in Ian Kershaw’s classic interpretation. If we conceptualize charisma merely as a sort of talent, Hitler was an unlikely candidate for leadership. Not to put too fine a point on it, he was a loser. To be sure, he did have some qualities, including “massive overconfidence”, that would help him later in his rise to power, and he was well-served by the fascist genius for ritual spectacle; but none of these qualities, by themselves, explain his later charismatic authority over millions of people. (At best, they would have made him a moderately successful rabble-rouser — what he in fact was in the early 1920s).
What really invested him with charismatic authority among many Germans in the 1930s were his successes, including his unlikely electoral gains, his astonishing diplomatic and military victories after he gained power, and perhaps most of all the taming of German unemployment. It did not matter much whether some of these successes were actually attributable to Hitler, or based on illusory assessments, so long as he was visibly associated with them. And because Hitler wildly exceeded initial expectations (he was, after all, a perfect outsider), too many people adjusted their priors “too much” in the direction of “miracle worker.” But by the same token, when his decisions led to a massive failure that he had to take responsibility for (in particular, the defeat at Stalingrad) his charismatic authority started to ebb. (It had to be a massive failure, by the way: minor failures would not have dented his reputation much, as they would have been easily rationalized).
Similar stories could be told for other classic cases of charismatic leadership in this period. A common thread in these stories seems to be that leaders who are later said to be charismatic are successful bluffers, outsiders who make unlikely gambles and win. Mussolini with his “March on Rome” is another case in point. The march represented no big threat to the Italian state (Prime Minister Luigi Facta was ready to impose martial law to prevent it, and would likely have succeeded), yet king Vitorio Emmanuele III folded and gave Mussolini the prime ministership. This success was one event that helped construct Mussolini’s charismatic authority, complementing the ritual dimensions of fascist rule. Fascist spectacle by itself was insufficient; Mussolini, another paradigmatic outsider, required unlikely, striking successes for large numbers of people to greatly increase their trust in him as a leader. But again, when he failed, his charisma quickly ebbed, and he came to depend more and more on the legal authority of the state rather than on his personal authority as a charismatic leader.
