He used this belief to help many different rulers. He helped leaders in Portugal and Bohemia. He even tried to influence the Mongols in the East. He also allowed crusades in places like Prussia and Livonia. He issued a special paper called a bull to allow this. These papers helped guide the actions of the Church.

The law allowed officials to use torture to get information. It said they should not kill or break limbs. This was a very serious and difficult part of his rule.

Pope Innocent IV was a powerful leader of the Catholic Church. 
In 1243, the cardinals elected Sinibaldo as the new pope. He took the name Innocent IV. He did not want the role at first. He inherited a massive dispute regarding lands seized by the Holy Roman Emperor, Frederick II. This conflict involved the Patrimony of St Peter and the region of Lombardy. The struggle between the papacy and the empire defined much of his reign. Frederick II had previously tried to intimidate the Church by arresting two cardinals. This interference had prevented them from participating in the previous election of Pope Celestine IV. The election of Innocent IV followed a year and a half of intense debate among the factions.
Relations between the Pope and the Emperor were very tense. Frederick II once joked that by electing Sinibaldo, he had lost a friend but gained an enemy. Despite this, Frederick sent a respectful letter wishing the new pope success. However, negotiations failed because neither leader would yield. Innocent IV refused to stop demanding the return of Church lands. The Emperor's actions created strong anti-papal feelings across Italy. Because of imperial plots against his safety, Innocent had to flee Rome in June 1244. 
In Lyon, Innocent IV organized a major religious meeting called a General Council. 

Innocent IV held a very specific view of political power. He believed the Pope was the Vicar of Christ. This meant he believed the Pope's authority was higher than any earthly king. He used this idea to intervene in secular matters across Europe. He appointed administrators in Portugal and protected leaders in Bohemia. He even sided with King Henry III of England against certain nobles and bishops. He believed his authority even extended to non-Christians, such as the Mongols. He claimed he could demand they follow the Ten Commandments. This theory of universal papal dominion was later rejected by the Church.
During his reign, Innocent IV also authorized military actions known as crusades. In September 1243, he issued a papal bull called Qui iustis causis. This document gave permission for crusades in Livonia and Prussia. The Teutonic Order sought his support to fight against the Lithuanians and suppress Prussian rebellions. He reissued this authorization several times between 1243 and 1257. He also issued a famous legal document in 1252 called Ad extirpanda. 
The conflict with the Hohenstaufen dynasty continued even after Frederick II died in 1250. Innocent IV returned to Italy and traveled through cities like Milan, Perugia, and Bologna. He spent his final years managing the succession of the lands previously held by Frederick's heirs. He supported any party that opposed the Hohenstaufen family. This policy kept Italy involved in many conflicts for thirty years. Innocent IV died in Naples on 7 December 1254. He passed away while following the papal army that was seeking to defeat Frederick's son, Manfred.
