In the world we are today, we don't have leaders but rulers because when we talk about being a leader, it has a lot of responsibility that is attached to it such that a leader is meant to make sure that those responsibilities are fulfilled in the course of serving the people but it's very unfortunate that people are just interested in ruling to their own personal gains and not to the interest of the masses.

Now to your question what makes a great leader? A great leader is one who has the interest of her followers at heart and is more concerned on the well-being of his subjects. So what makes a great leader is being self disciplined, obedience, and being compassionate to those who needs help in the society.
