What is feudalism, and what conditions in Europe (here is a clue: after the fall of Rome )led to the development and spread of feudalism

Feudalism is the economic and social order in Europe.

Explanation:

It is characteristic of the Middle Ages. It arose as a result of the fall of the Western Roman Empire. Namely, the economic and social order characteristic of the Roman Empire was slavery. Slavery is an ancient pattern that disappeared along with the Western Roman Empire. With the penetration of Germans and Slavs into Europe, feudalism emerged. As these peoples became more and more important, so did feudalism. At the top of the pyramid list in feudalism was the ruler. He gave land to the nobles, and in return, the nobles had to provide an army to the ruler in case of war. The land was cultivated by serfs at the bottom of the social ladder (but were free, unlike slaves), and could keep part of that land's income.

the california missions began in the late 18th century as an effort to convert native americans to catholicism and expand european territory. there were 21 missions in all, lasting from 1769 until about 1833.   the missions were built by the spanish starting in 1769 in order to “colonize” the territory of alta california. so the missions were important because they were the means of settling california. it also wanted to keep other european countries out of alta california. building settlements along the coast would them meet these goals. missionaries wanted to convert the indians to the roman catholic faith. california indians did much of the work to build missions.
