Final answer:
Guilds paid taxes, helped raise armies, and provided other services for their feudal lords.
Step-by-step explanation:
Guilds paid taxes, helped raise armies, and provided other services for their lords. The feudal system was based on a kind of protection system, where lords offered protection and land-grants to vassals in exchange for their support in war. In return, vassals provided military service and other obligations to their lords. Guilds, as vassals, fulfilled their obligations by supporting their feudal lords in various ways.
