How did William Wallace inspire the lower-class citizens to revolt against the king and his men?

Wallace attempted to make alliances with other Scottish nobles, with varying degrees of success, and also with Robert the Bruce's father, who was of the opinion that submitting to the English was the only way in which he would secure the Scottish throne for his son. He was betrayed by Robert, who invited him to a meeting in Edinburgh, only to capture him and hand him over to the English.

He was tried by a magistrate and found guilty of high treason, the punishment for which was public torture and execution. He was hanged, drawn and quartered, but to the end refused to swear allegiance to the king. He gained support from the crowd watching his execution and they called for mercy, but he would not agree to ask for mercy for himself, and so was beheaded.
