Greatest Ruler in History Tournament

If history has taught us anything, it is that a lot of rulers show up, conquer land, while others defend it. Who is your favorite?

 

You get to decide! 150 rulers compete to see who is the greatest ruler of all of them. Every week, there will be 2 rulers or explorers going up against each other.  I will provide information on the candidates and you must vote by the end of the week.

Here is the brackets and formats:
