The contents of the gold and silver treasure pot of plunder of a Tatar (Mongol) leader from ca. 1400, which has recently been discovered in Bulgaria's Kaliakara Cape Fortresson the Black Sea coast, is a true testimony to the decline of the medieval Bulgarian Empire and the Byzantine Empire before the Ottoman conquest.

In this specific find, the decline of the empires of Bulgaria and Byzantium in the Late Middle Ages is evidenced primarily from the really meager silver and gold content in thecoins of the Bulgarian Tsars and Byzantine Emperors found in the treasure pot whose contents were seemingly plundered during the last Balkan invasion of the Tatars (Mongols).

The clay treasure pot , which was founded on August 17, 2018, in the Kaliakra Fortress, contains 957 archaeological artifacts from the 14th century, including 28 gold coins,873 silver coins, 11 gold appliques and buckles, 11 gold earrings, 2 rings, one of which is gold, four beads made of gold and precious stones, and 28 silver and bronzebuttons.
