The development of pike and pike tactics in the late 13th-early 14th century was a major contributor to the decline of the importance of aristocratic heavy cavalry in warfare. They didn’t lose all importance, but when a well-trained militia can repel your very-expensive landed warrior elite, you start to do some recalculation of the military budget, so to speak.
One could argue that the nivelization of the populace by the plagues did more to break up the feudal hegemony. If the population declines by a huge amount the power goes back to the people that do the work.

A lot of factors, really. Very happening place, the Late Medieval/Early Renaissance period.
