Who were the leading families of spain england france, and german states?

One of the most significant developments in the three centuries leading up to the Renaissance period was the collapse of feudalism. This social and economic system had emerged during the ninth century in the Carolingian Empire (pronounced care-eh-LIN-jee-ehn), which was centered in the region that is now France. (See "Feudalism" in Chapter 1.) Eventually feudalism (a term derived from the medieval Latin word feudum, meaning "fee") spread throughout Europe and served as a unifying institution for all aspects of life. Under feudalism, which was based on an agricultural economy, distinct social classes were dependent on one another through a complex system of pledging loyalty in exchange for goods and services. At the top were kings, who owned the land. Beneath them were lords (noblemen) and clergymen (church officials), who were granted tracts of land called fiefs (pronounced feefs) by the king. Below the lords were vassals (knights), who held smaller amounts of land awarded to them by lords. At the bottom were serfs (peasants), who farmed the fiefs but were not given land of their own. Land occupied by churches, monasteries (houses for men called monks, who dedicated themselves to the religious life), and other religious establishments of the Roman Catholic Church were also considered fiefs.
