Attila the Hun was a powerful leader of the Huns, a nomadic group from Central Asia, during the 5th century. He is often remembered for his fierce military campaigns against the Roman Empire, which made him a feared figure in Europe. Under his rule, the Huns expanded their territory and became known for their swift cavalry and brutal tactics. Despite his reputation as a ruthless conqueror, Attila was also a skilled diplomat. He negotiated treaties with the Romans, including the famous Treaty of Margus, which allowed him to extract tribute from the empire. His reign marked a significant period in history, influencing the decline of the Western Roman Empire.
