Chichen Nuevo began roughly about 850 AD. with the arrival of the Itza from Central Mexico.
The city was rebuilt by the Itza. It is also characterized by images of the god Kukulcan, the plumed serpent.
Around 1150 AD. a new wave of Itza took over the city and ruled for another 150 years more until Chichen Itza was finally overtaken by the rival city of Mayapan.
