How was a town able to become independent of a fuedal lord?

A town could become independent of a feudal lord through various means, such as negotiating a charter that granted it self-governance and certain rights. This often involved the payment of a lump sum or annual fees to the lord in exchange for autonomy. Additionally, towns might leverage their economic importance, such as trade or resources, to assert their independence, or they could form alliances with other towns or seek protection from a higher authority, like a king. Over time, these factors led to a gradual erosion of feudal control and the establishment of municipal independence.
