1 Lat 1 Tamlung

Lan Xang — "Kingdom of a Million Elephants" — dominated the middle Mekong through much of the seventeenth century, controlling lucrative overland trade routes connecting China to the Gulf of Siam. These billon issues functioned within a weight-based monetary system tied to the lat and tamlung units long before European coinage conventions penetrated the interior of mainland Southeast Asia. The kingdom fractured into three competing successor states after 1707, which effectively ends the attribution window for this type.
