Constantine V was a powerful leader of the Byzantine Empire. He ruled as emperor from 741 to 775. 
Constantine's life began with many important roles. He was the son of Emperor Leo III. At only two years old, he became a co-emperor. This means he shared the throne with his father. 

Being an emperor was not always easy for him. Right after he became the sole ruler in 741, a man named Artabasdos rebelled. Artabasdos was Constantine's brother-in-law and a military governor. The two leaders fought for control of the empire. Constantine had to flee to a place called Amorion to find safety. He eventually gathered his own soldiers to fight back. In 743, Constantine defeated Artabasdos at a place called Sardis. After more battles, Constantine entered the capital city of Constantinople. 
Religion was a huge part of Constantine's rule. He supported a movement called iconoclasm. This was a belief that people should not use religious images. Constantine argued that God could not be shown in a picture. 
Because of these religious fights, Constantine had many enemies. These enemies wrote unkind things about him in history books. They even gave him rude nicknames to make him look bad. Some people claimed he was not fit to be a leader because of his health. They also spread rumors about his childhood to insult him. Despite these struggles, Constantine remained in power for many years. He changed how the empire was run and how the army worked. His long reign left a big mark on Byzantine history.
Constantine V was a significant Byzantine emperor who ruled from 741 to 775. His reign was a period of intense military activity and deep religious change. He is remembered for strengthening the empire's borders against external threats. 
Constantine's rise to power began very early in his life. He was the son of Emperor Leo III and Maria. In 720, when he was only two years old, he became a co-emperor. 

His transition to sole emperor in 741 was immediately challenged by a civil war. His brother-in-law, Artabasdos, led a rebellion against him. Artabasdos was a military governor, known as a strategos, of the Opsikion theme. The conflict forced Constantine to flee to Amorion to find safety with local soldiers. The two sides fought several battles, including a confrontation at Sardis in 743. Constantine eventually defeated Artabasdos and his son, Niketas, at Modrina. After a siege, Constantine regained control of the capital, Constantinople.
One of the most defining aspects of his rule was his support for iconoclasm. Iconoclasm was a theological movement that rejected the use of religious images, or icons. 
In 754, Constantine convened the Council of Hieria to formalize these religious policies. This council was attended by iconoclast bishops who declared the veneration of icons to be anathema. An anathema is a formal curse or exclusion from the church. While the council supported iconoclasm, it did not agree with every extremist view. For example, the council still upheld the status of Mary as the Theotokos, or "Mother of God." It also protected the use of terms like "saint" and "holy" within the church.
Constantine's enforcement of these policies led to direct conflict with monastic communities. Monks were often the strongest supporters of the iconodules, those who defended religious images. The Emperor's general, Michael Lachanodrakon, led efforts to seize monastic property for the state and the army. Resistance was met with harsh punishments, including exile and blinding. Some monks, such as Stephen the Younger, faced even more severe consequences for their opposition. These tensions caused many religious figures to flee to places like Sicily and southern Italy.
Because of these intense religious struggles, Constantine's reputation suffered in later history. Many writers who supported icons were also enemies of the emperor. They used derogatory nicknames to insult him, such as "Dung-Named." These names were based on rumors that he had defiled his baptism as an infant. Some historians also noted he may have suffered from a medical condition like epilepsy. Despite these insults, Constantine remained an effective military leader. He successfully defended the eastern frontier and conducted campaigns against the Bulgars in the Balkans. His reign helped stabilize the empire's territories through military strength and strategic population shifts.
