I want to know the answer to the following question:
Who was at the top of the power pyramid in Sumerian society?
All the background I'm provided with is that "Beneath the lu-gal ("great man" or king), all members of society belonged to one of two basic strata: The "lu" or free person, and the slave (male, arad; female geme).". Is that enough to answer the question?
Answer: yes
