Why did height taxation make the barons rebel against king john?

Height taxation, specifically the tax on the amount of land owned, was seen as an unfair burden by the barons, who were already feeling discontent with King John's rule due to his heavy taxation and military failures. The barons viewed this tax as an infringement on their rights and a sign of the king's increasing tyranny. The rebellion was fueled by their desire to protect their privileges and restore traditional rights, ultimately leading to the Magna Carta in 1215. Their revolt was a reaction against what they perceived as John's exploitation and mismanagement of power.
