The Maya civilization was one of the most advanced ancient civilizations in the Central and South America before arrival of Europeans. They had an estimated reign of over 2000 years. The Maya developed a written language using hieroglyphs, art and architecture, mathematical and astronomical systems. They built huge stone pyramids, sculpture and temples. The Maya achieved their highest state of development during the period between 300 AD and 900 AD. After 900 AD the Maya mysteriously declined in the southern areas, but continued to thrive till the arrival of the Europeans.
