I've been interested in this for awhile, but everything I've looked up about it basically just told me that a bunch of barbarians took over the area and united under Christianity.
Mind you, this was a pretty gradual process; many of these various barbarians were more like immigrants to the Roman empire than invaders, and saw much to admire in the Roman culture, adopting parts of its legal code along its religion, etc. Also, the Empire as such wasn't gone, it had just lost its western and poorer half, and was left with one Emperor instead of two.
That doesn't really help me. How did all of these countries that were around at the Renaissance(England, France, Spain, Ottomans, Italy) even come about? I know a little bit about Charlemagne and the Crusades, but other than that my knowledge of Western Europe in the Middle Ages is very limited.
Basically I'm asking, from after the fall of Rome(5th century I guess) what happened in Europe that made all of these huge powerful countries rise up. Just a general outline would be good.
1. Breakdown of centralized western Imperial authority and trade leading to rise of locally-based feudal authorities. A bunch of ruinous wars large and small with various causes, both between different "barbarian" kingdoms and involving the eastern Empire trying to reassert authority. Three hundred years of petty history where most of the details are of interest to specialists only.
2. Islam shows up after a while, kicks the Eastern empire out of North Africa (which
really really hurts said empire) and gets as far as conquering the Iberian peninsula before running out of steam.
3. Charlemagne is definitely key. Powerful, ambitious ruler of the large Frankish kingdom, he extended his rule across nearly all of modern France plus much of Italy and Germany. Was a fan of book-learning and sponsored monasteries and general education heavily; the Latin language wouldn't have been as important for the following thousand years if not for this. He had ambitions of restoring the whole of the Roman empire as a unified entity, but "only" managed to revive the title of Emperor of the west (officially approved by the Pope at the time). Because the Franks still used to split their kingdoms among their sons (when there was more than one), his empire fragmented after his death.
4. By this time most of those feudal barbarian nations from point 1 have become converted to Christianity, and said religion keeps spreading far beyond the previous borders of the Empire. There's still not a really clear political or theological split between the western (Latin-speaking) and eastern (Greek-speaking) churches. The title of (Holy Roman) Emperor remains for a long time, although its political significance is slowly eroded over the coming centuries. More feudalism, Vikings show up and cause trouble for a while (until their homelands are Christianized), people build cathedrals etc. The idea of the nation-state is far in the future, folks owe allegiance to their families or a particular chieftain or baron or king or whatever, but sometimes also to an overarching ideal (see "Crusades" for example).
5. Crusades and increasing transcontinental trade bring and mix different technologies and ideas together. Gradually increasing urbanism, etc. Then comes the Black Death and gives the established economic order a kick in the pants; as the chaos settles a bit, land has become much cheaper and labour more expensive, this eventually sets the stage for more centralization of power and economy as well as the growth of the urban classes.
6. The actual modern nation-state, based on the geographical, cultural and/or linguistic identity of its population, is a
very modern concept, as in 19th century modern (with a few earlier precursors). From the point of view of the late Middle Ages it lies on the other side of a whole lot of goobledegook about the Divine Right of Kings (
not a medieval concept) and some rather nasty history such as the 30 Years' War,
cuius regio, eius religio, the French Revolution, etc.
