I have to admit that I'm hearing about Chanakya for the first time through your article. It was a nice and interesting read for me.
To answer your question, I would say that he apparently showed the skills, knowledge and the character of a leader, but somehow I would rather call him as a great psychologist and a very wise man who understood very well the law of life, human nature, and the common interaction of the two.
He was great economist too. Read about him if possible you will see everything in your life whatever he has said long ago.
So did I :)
