This ring was discovered on a woman buried around 1,200 years ago in Birka, an ancient Viking city located 30 km (19 miles) west of contemporary Stockholm, Sweden. What sets this ring apart is the inscription “for Allah” in Kufic Arabic, commonly used between the 8th and 10th centuries. It provides evidence of direct contact between Vikings and the Abbasid Caliphate, the third caliphate succeeding the Islamic prophet Muhammad.
