while the serf was sweeping the manors cellar a rat that carried fleas with the bubonic disease, the flea ran off and bit him, this happened to many serfs, very often. This is because they livied in suh bad conditions
the serfs fell sick because of the disease. Causing a lot of serfs out of the capability to work and then they die.
i have no knights
this lead to serfs being in high demand and they began to hold "value", thus leading to serfs asking for better pay, treatment, and living conditions. so they threatended their masters that they would leave and fight, because the priest said that if you went to fight you would go to heaven, so they believed either way ending in better life. (if they didnt die of the plague)
i have no job!
I HAVE NO LAND!
I HAVE NO PROTECTION OR SERFS!
when knights went to fight in the crusades the english had a weapon called the "longbow" wich was very poweful and killed the knights within seconds of stepping onto the battlefield. thus leading to lack of knights, they becames useless and they all just died.
this lead to lords having no knights to give to the kings in return for land, s their land was taken away and serfs lost thei jobs
serfs left manors to fight and go to heaven and they got sik or they demanded better treatment because of their new found "value", knights kept dying in war and became scarce and so this lead to lords having no nights to give the king in return for land, leading to kings, lords, and knights losing serfs to work their land, then they lost their land, then they lost their jobs.
