Are you asking for the 800s or the 1800's(assuming you had a typo? i'll answer both anyways)
In the 800's, Charlemagne was crowned king by the pope, and Europe was under attack by all sorts of surrounding tribes, like the Vandals, Goths, Angelo-Saxons and more. It was a war zone.
In the 1800's, the economy grew, and there were more labor. More Europeans entered America and brought unknown diseases. I guess it was Europe's Industrial revolution.<span />
