Question

Answer 1

new influxes of random people not from the areas such as fleeing muslims, Asians, tribesmen, new trade routes being cut through city centers, raised taxes due to war debt, damage, and import fees due to dangers that threatened the caravans on the roads, and the most important is the raise in city safety!
