Henry V of the Holy Roman Empire was a significant ruler who reigned from 1111 to 1125. He was a member of the Salian dynasty and became king after his father, Henry IV. His reign was marked by efforts to strengthen the authority of the monarchy and to resolve conflicts with the papacy. Henry V is best known for his role in the Investiture Controversy, a power struggle between the monarchy and the church over the appointment of bishops. He sought to establish a balance of power, which ultimately led to the Concordat of Worms in 1122, a pivotal agreement that helped define the relationship between the church and the state.
