In what way were the Crusaders both successful and unsuccessful? (PLEASE FAST!!) (YOU WILL GET BRAINLEST)

The crusader's were successful in spreading the Religion and taking down all other religions, basically making a terror monarchy with Christianity. They made most Muslims scared of them so they surrendered from battle. They were unsuccessful because they didn't have a very good leader after the first 2 crusades', most leaders would die on the way or get killed by assians. With no one to lead these crusades they fell apart and didn't accomplish very much.

explanation:

on november 6 and 7, 1917 (or october 24 and 25 on the julian calendar, which is why the event is often referred to as the october revolution), leftist revolutionaries led by bolshevik party leader vladimir lenin launched a nearly bloodless coup d'état against the duma's provisional government.
