The Synod of London convened in 1172, bringing together church leaders to address various ecclesiastical issues, including the authority of the church and its relationship with the monarchy. This synod was significant in shaping the governance of the church in England, particularly in the context of the ongoing conflict between King Henry II and Thomas Becket. The decisions made here would have lasting implications for church-state relations.

The Synod of London influenced the literary landscape by highlighting the tensions between church and state, themes that would be explored by poets and playwrights in later centuries. The conflict surrounding Becket's martyrdom inspired works such as T.S. Eliot's 'Murder in the Cathedral,' reflecting on the moral and spiritual dilemmas faced by individuals caught in the struggle for power.
