He ruled from 434 to 453 AD and is known for his military campaigns across Europe, which instilled fear in the Roman Empire. His forces were skilled horsemen, and they used swift tactics to conquer various territories. Attila's reign marked a significant period of conflict between the Huns and the Roman Empire. He is often remembered for his brutal tactics and the destruction he caused, earning him the nickname "Scourge of God." His death in 453 AD led to the decline of the Hunnic Empire.
