This concept is an anachronism according to Elizabeth A. R. Brown’s 1974 article The Tyranny of a Construct, (15[1])which cites Frederic Maitland’s rejection of this concept’s presence in England. (-5[1])Marc Bloch applied this concept to each of the three estates, unlike François Louis Ganshof, who limited it to reciprocal obligations (15[1])among the warrior nobility. (15[2])Karl Marx considered this (15[1])system to be the mode of production (15[1]-5[1])preceding (*) capitalism. (10[18])This (10[2])system (10[2]-5[1])allowed for the aggregation (10[2])of land (10[1])among (10[1])the (10[1])lower nobility, (10[2]-5[1])contributing (10[2])to the (10[1])rise (10[1])of manorialism. (10[1])People in this system (10[1])participated in ceremonies (10[1])consisting of a two-part act of homage and an oath of fealty. For 10 points, name this political and economic system of medieval Europe (10[1])whereby lords granted fiefs to vassals. ■END■ (10[4])
