Flag of the Republic of Yucatán, civil insignia of the Yucatecan without legal recognition.

The flag of Yucatán was raised on March 16, 1841. The period of the Republic of Yucatán was the only one in which the banner was officially used by the authorities of Yucatán.

Rodolfo Menéndez de la Peña, historian, describes the flag of Yucatán: “The flag of Yucatán was divided into two parts: green on left, the right, with three divisions, red up and down and white in the middle. In the green field highlighted, five stars, symbolizing the five departments that Yucatan was divided by decree of November 30, 1840: Mérida, Izamal, Valladolid, Tekax and Campeche.”

The flag does not have official recognition in the state, however, it has a strong recognition among the people of the state.[40][41] De facto state flag, in any case, according to a convention led by former president Ernesto Zedillo, is a white flag with the shield of the state in the middle.
