Chik'in Kingdom
The Chik'in Kingdom, also known as the First Tullan, the Danguixh Hegemony, and very rarely referred as the Tatinak Kingdom, was a state located in the Mutul that existed between the third century BC to 304 AD when it became known as the Kuy Dynasty. It's capital was Danguixh, which grew to become one of the largest cities of its time with a population of 125,000 inhabitants intra muros.
Today, the Chik'in kingdom is famous for being the first "foreign" state to claim the mantle of Mutul and to unite both the west, center, and northern regions of the modern day Divine Kingdom. Many antiques and art works from its period have survived, and its influence continue to be felt to this day, having popularized religious figures such as the Feathered Serpent. Both its architectural styles and costumes would continue to be used in the Mutul for the following centuries of Kuy domination.
While it's end is officially placed in 304 AD, it was by all accounts a mere change of name, and the kingdom became the prestigious Kuy Dynasty which lived on for the next six centuries.
