ecreed its separation from Mexico and Miguel Barbachano, then governor of Yucat�n, sent a commission headed by Justo Sierra O'Reilly to meet with Tabasco authorities to propose the creation of an independent federal republic from Mexico formed by the two states. The idea failed when Tabasco rejoined Mexico in 1842.
On August 22, 1846, Mexican interim president Jos� Mariano Salas restored the 1824 constitution and the federalism. Two years later, during the government of president Jos� Joaqu�n de Herrera, Miguel Barbachano ordered the reinstatement of Yucat�n to Mexico under the Constitution of Yucat�n of 1825. A decisive factor for the reinstatement was the Caste War, which forced Yucat�n to seek outside help. In 1852 due to internal struggles between opposing political factions, was created the Territory of Campeche. On April 29, 1863, during the government of Benito Ju�rez, Campeche gained its current status as an independent state.
Flag of Yucat�n
The flag of Yucat�n was raised on March 16, 1841. The period of the Republic of Yucat�n was the only one in which the banner was officially used by the authorities of Yucat�n.
Rodolfo Men�ndez de la Pe�a, historian, describes the flag of Yucat�n:
� The flag of Yucat�n 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: M�rida, Izamal, Valladolid, Tekax and Campeche. �
The flag doesn't have official recognition in the state; however, it has a strong recognition among the people of the state. 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.

The Caste War of Yucat�n was a conflict that lasted from 1847
