Vasily I began issuing coins with Arabic inscriptions — or imitations of them — as a political signal to the Golden Horde, whose nominal suzerainty over Moscow he was still carefully managing. These legends were never meant to be read; Muscovite die-cutters had no knowledge of Arabic script, producing garbled pseudo-Kufic that functioned as visual acknowledgment of Tatar authority without meaningful content. The practice was common among Rus' princes of the late 14th and early 15th centuries, though the specific period of 1412–1416 coincides with the succession crisis following the death of Khan Toqtamish and the resulting instability across the Horde.
