From today's featured article.jpg) Silver coin of Constans II Constans II (died 411) was the son of the Western Roman emperor Constantine III. When his father rebelled against the ruling emperor Honorius and the army in Britain acclaimed him as emperor in early 407, Constans was a monk. He was summoned to Gaul, appointed to the position of caesar (heir) and swiftly married so that a dynasty could be founded. Honorius acknowledged Constantine as co-emperor in early 409 and Constantine immediately raised Constans to the position of emperor, theoretically equal in rank to Honorius as well as to Constantine. Later in 409 Constans was sent to Hispania (Spain) to quash a revolt, but suffered a defeat and withdrew to Arelate (modern Arles). In 410, Constans was again sent to Hispania with an army. The rebels had strengthened their forces with barbarians and won a battle against Constans; he withdrew north and was defeated again and killed at Vienne early in 411. The rebels then besieged Constantine in Arelate and killed him. (Full article...)

Nader Shah Afshar (6 August 1698 or 22 October 1688 – 20 June 1747) was the founder of the Afsharid dynasty of Iran and one of the most powerful rulers in Iranian history, ruling as shah of Iran from 1736 to 1747, when he was assassinated during a rebellion. He fought numerous campaigns throughout the Middle East, the Caucasus, Central Asia, and South Asia, emerging victorious from the battles of Herat, Mihmandust, Murche-Khort, Kirkuk, Yeghevārd, Khyber Pass, Karnal, and Kars. He has been described as "the last great Asiatic military conqueror", and his victories during his campaigns briefly made him West Asia's most powerful sovereign, ruling over what was arguably the most powerful empire in the world. Nader also changed the Iranian coinage system, minting silver coins, called Naderi, that were equal to the Mughal rupee. This silver coin was minted in Dagestan and is dated 1741–1742.
