If you ask the question publicly expect nothing less than argumentative and disagreeable discussions.
We may consider
leadership politically, historically, from the business prospective and many more aspects and settings.
This topic has been rolling in my mind for a long time now because I am looking for the best leadership practices and also the people performing them. I was amazed by people’s approach to this question on the internet. It has almost nothing to do with leadership but rather about personalities that important people have or had. You may find ‘answers’ under the titles like ‘XYZ Things the greatest leaders all have in common’, ‘Who are the greatest leaders of all time?’ or ‘The greatest leader of all’ and similar.
Are they describing basic leadership methodology and then, based on it, show who the great leaders were (are)? No, they are not! Do these articles have anything in common then? Absolutely yes!
Most of the researches are listing what a leader should not lack. See what I wrote in the blog
Added value of leadership names or labels: “Is it all about different behaviors, different styles, or just to give a new label in front of the word leadership?” Those articles just state the “names” (mostly applied in western societies while forgetting the other parts of the world) and what those leaders were great for. Some go deeper and explain what leaders contributed to their societies.
