During the 'High' Mediaeval period, the armies of Europe were based on a feudal system, with each Baron, Earl etc providing troops in return for his position. These titles too were awarded in order to buy favour, though many times we have seen the outcome decided by the armies of some Duke who can't decide which side to join. There is no way that these armies consisted of men-at-arms and mounted knights. The vast majority were peasant farmers, miners and the like and as for weapons, they were usually the tools of their trade. I am sure CBR will agree with me when I say the spear was by far the most popular weapon of the period
