Yes indeed.

Emergence of charismatic leadership is definitely depends on the situation Charismatic leadership process is seen as a compound product of three factors: The leader and his attributes, the social situation which demands for such a leader and the interaction between the leader and his followers.
It is a stage where the aspiring leader is on the social horizon; the followers are in distress and are looking forward to someone who will identify himself with their problems.
The social situation is increasingly getting worsened in this stage.
This is the time when the leader establishes him as a potential leader but the followers, by large, remain passive.
The leader arouses the follower to become the part of the change.
Followers who were passive admirers of the leader till the earlier phase become active supporters of the leader and the cause for which he is identifying himself.
The Leader starts by demonstrating the extreme commitment towards the goal and same commitment from the followers towards the leader.

Sure, that's the secret of being a great leader.

Charismatic leaders appears most successful when the follower’s task has an ideological component or the environment includes a high degree of stress and uncertainty

Charismatic is not him that resolves the situation........Is him that in every problem finds a great opportunity....
