Final answer:
Craftsmen played an important role in urban economies as cities grew in population. They engaged in craft production, were organized into guilds, and worked in private or state workshops to earn wages.
Step-by-step explanation:
Once cities grew in population, craftsmen played an important role in urban economies. They engaged in craft production and were often organized into guilds. With the growth of towns and cities, craftsmen had more job opportunities in private or state workshops, where they could earn wages.
The increase in urban population also created a greater demand for skilled and unskilled labor, which led to the expansion of the craft manufacturing industry.
