This 2007 History Channel documentary talks about what happened between the fall of Rome in 410 AD and the Crusades starting in the 1000’s AD.  It focuses on the conquests of Clovis to form the Franks and modern France; the rise of Christianity in Europe;  the advent of the first bubonic Plague in 542 AD, killing up to 50% of the populations in urban areas of Europe; the invasion of Europe by Muslims in 732 which was rebuffed by Charles Martell in France at the Battle of Tours, saving Europe from becoming Islamic (and his grandson Charlemagne eventually becoming the Emperor of Rome); Charlemagne becoming the first Roman Emperor in 300 years at around the year 800, where he restored much of Europe to Roman control and brought health to the continent such as by instigating the education of the populace; the devastating Viking attacks in Europe between 793 and 950; King Alfred rebuffing the Vikings in southern England in the late 800’s; medieval knights starting to subjugate the populations of Europe starting in the 900’s; and the Crusades being undertaken in 1095.
