Actually, feudalism was invented in 788 by Charlemagne as a superior alternative to Roman Capitalism. Other proposed models around this time were Anarcho-syndicalism, Democracy, Communism, Stalinism, Theocracy, and Serpentocracy. Although some of these were superior to feudalism, the representative for anarcho-syndicalism was removed from the convention for contempt, the representative for theocracy failed to attend, and the representative for Serpentocracy had other matters that prevented him from appearing(being a snake is a busy life).
