Thomas Becket was a leader in the English church. 

Thomas and King Henry II had many fights. They argued about the rights of the church. The king wanted more power over church rules. Thomas did not agree with the king. This led to a big split between them. Thomas even fled to France for a while.
In 1170, Thomas returned to England. Four men who followed the king went to his cathedral. 

Thomas Becket was a very important leader in the English church. 

In 1162, Becket became the Archbishop of Canterbury. 

History tells us many stories about this time. Many writers wrote biographies about Becket's life. Some writers are known, like John of Salisbury and Edward Grim. Other writers left their names out of their books. 
On 29 December 1170, a sad event happened in Canterbury. 

People across Europe were very moved by his death. 
Thomas Becket was a central figure in the twelfth-century struggle between church and state. 

Becket's career moved through several significant stages of leadership. In 1154, he was named Archdeacon of Canterbury. His efficiency in this role led King Henry II to appoint him Lord Chancellor in January 1155. As chancellor, Becket managed the king's traditional sources of revenue. This included taxes from landowners, churches, and bishoprics. 
A major conflict emerged between Becket and King Henry II regarding legal jurisdiction. The king sought to expand royal authority over the clergy through the Constitutions of Clarendon. 

The tension reached a breaking point due to Becket's religious actions. In November 1170, Becket excommunicated several high-ranking officials, including the Archbishop of York. These officials had participated in a coronation that breached Canterbury's traditional privileges. Upon hearing of these actions, Henry II reportedly expressed anger toward the "turbulent priest." 
The assassination occurred on 29 December 1170 inside Canterbury Cathedral. 
Following his death, Becket's status changed rapidly within the Christian world. Many people viewed him as a martyr because he died for his religious convictions. 
Our understanding of Becket comes from a wide variety of historical documents. Many contemporary biographers wrote about his life, including John of Salisbury and Edward Grim. Others remained anonymous, known only as Anonymous I, II, or III. We also rely on medieval chronicles written by figures like Roger of Howden and William of Newburgh. These texts, along with works like the *Quadrilogus*, provide the details of his rise and fall. This body of writing helps historians trace the complex relationship between the English monarchy and the medieval church. The life of Thomas Becket remains a significant study in the history of political and religious power.
