Answer:
What made Washington a great leader was his understanding of what had to be done. As president, Washington realized that the new Constitution had to be made to work if democracy was to take root in American soil. This would not happen if he had chosen to become a lifetime king or if federal laws were ignored.
George Washington is one of the greatest, because he alone knows that for an empire to be truly great, it cannot be confined to himself. George Washington, at his peak days, could have became president of America for many many terms, perhaps even for life, like many dictators would do.
