don't listen to >>17862060 he's an absolute fucking midwit who's entire breadth of knowledge comes from the history channel. citizinship started as a necessity for the sake of identification in ancient sumeria. men and women wore cylinder seals (small cylinders made out of various stone or crystals) that had engravings in them. they would roll these seals onto clay to sign things, and each person had their own. foreigners and slaves did not have these seals, so it was proof of citizenship for free people. this practice continued in mesopotamia for thousands of years.
