Maya (c. 1998)
Well the world didn’t come to an end today, but don’t blame the Maya; their only sin was having an easily misinterpreted calendar system.
The ancient Maya didn’t have flags, but there are still millions of Maya people living in Central America. This flag was reported as being used by the Maya of Guatemala in 1998. The four triangles were said to represent the sky (blue), the sun (yellow), fire (red), and peace (white).
