feudalism แปลว่า

"It was the beginning of a feudalism of the range, a barony rude enough, but a glorious one, albeit it began, like all feudalism, in large-handed theft and generous murdering."

"The re-emergence of empire was thwarted by immense topographical variety, coastal confolutions, and wide-openness to the east, which made Christendom difficult to organize and defend as a whole from Viking, barbarian and Islamic attacks round its perimeter; by natural temperateness, which rendered large-scale disasters needing widespread rescue of populations rare (Jones 1981); and by the very devolved political system represented by feudalism, which encouraged the fissipation of whatever larger units did develop."
