Athaulf was a Visigothic king who ruled from 410 to 415 AD. He succeeded Alaric I, the first king of the Visigoths, and is known for his efforts to establish a stable kingdom in the aftermath of the fall of the Western Roman Empire. Athaulf sought to integrate the Visigoths into Roman society and even married Galla Placidia, the sister of the Roman Emperor Honorius, to strengthen ties between the two groups. During his reign, Athaulf moved the Visigothic capital to Toulouse in modern-day France. He aimed to create a new order that combined Roman and Gothic elements, promoting trade and cultural exchange. However, his reign was marked by challenges, including conflicts with other tribes and internal dissent, which ultimately led to his assassination in 415 AD.
