Can someone please help me found out the answer to this question.

Discuss the relationship between inequality and war from the time of the earliest cities
(roughly 4000 BC) to the end of the Bronze Age (roughly 1200 BC). You may consider any form
of inequality in any group of people we have discussed. Possible considerations may include (but
are not limited to) the relationship between war and the rise of class societies and the state, or the
relationship of class and war as a factor in the Bronze Age collapse.

These may help:
