<span>The first major city in sumer was Ur</span>
Guilds were a medieval association of craftsmen or merchants who control the practice of their craft in a particular town or village.
The worker were the lower class and the poor. They did labour. They lived in the poorest and the dirtiest places in the city, furthermore that's how they got diseases, like smallpox and other really bad fevers. Also they mostly worked in textile factories. They accepted these jobs because that's the only jobs they could have. The owners treated them bad because they wanted the kids to work more and harder. Hope i helped :).
