Denga - Vladimir Andreevich

Vladimir Andreevich of Serpukhov, known as "the Brave," was the cousin who fought alongside Dmitri Donskoi at Kulikovo in 1380 — commanding the ambush force whose surprise flank attack broke the Mongol line. His principality's coinage reflects the fractured sovereignty of the Moscow satellite princes in the decades after Kulikovo, when tributary obligations to the Horde were loosening but not yet gone. These dengas circulated in a polity caught between Moscow's growing dominance and its own residual independence.

Vladimir died in 1410, and the principality was absorbed into Moscow within a generation.
