Where did baht come from?

The baht is the currency of Thailand, with its origins tracing back to the ancient trade system in Southeast Asia. Historically, it was derived from a silver weight system used in trade, with the term "baht" originally referring to a certain weight of silver. Over time, the baht evolved into a coin and, eventually, a modern currency, officially adopted in its current form in the 19th century during the reign of King Rama IV. The currency now plays a key role in Thailand's economy and international trade.
