Does the question you gave us a multiple choice question because I'm confused
Peter the Hermit was an attentive listener to Pope Urban II's cries and begged that people have to rescue the Holy Sepulchre. He was a monk and was part of the holy men in the audience. Because he was so stirred with the speech of Pope Urban II, he began preaching to men, women, and children in favor of war against the Turks.
He was able to gather many people and that started the Crusade. Alongside other leaders, he led one side of the troop and began the march. People waged to rescue Jerusalem from the Mohammedans. Therefore, the answer to this item is the first choice.
Yes. Because democracy is the tyranny of the majority. Thats why we are supposed to be a constitutional republic, that way minority rights are protected against mob rule.
