Explanation:
كان أورنامو أعظم ملك سومري means in translation Urnammu was the greatest Sumerian king
it is true this because he founded the Third Dynasty of Ur in Sumer (2047-1750 BCE) also known as the Sumerian Renaissance. He is best known as the king who composed the first complete law code in the world, The Code of Ur-Nammu ..so in my opinion a thing that could create a code of law and every one loved him makes me thing he was a great king
