Not the French, Yucatan itself. Heres what the Armenian Genocide has to say about it...
In 1847 the so-called "
Caste War" (
Guerra de Castas) broke out, a major revolt of the
Maya people against the Hispanic population in political and economic control. At one point in 1848, this revolt was successful to the point of driving all Hispanic Yucatecans out of almost the entire peninsula other than the walled cities of
Mérida and
Campeche.
The government in Mérida appealed for foreign help in suppressing the revolt, with Governor Méndez taking the extraordinary step of sending identical letters to
Britain,
Spain, and the
United States, offering sovereignty over Yucatán to whatever nation first provided sufficient aid to quash the Maya revolt. The proposal received serious attention in
Washington, D.C.: the Yucatecan ambassador was received by
US President James K. Polk and the matter was debated in the
Congress; ultimately, however, no action was taken other than an invocation of the
Monroe Doctrine to warn off any European power from interfering in the peninsula. The Yucatan government attempted to recruit American veterans of the Mexican American War to put down the rebellion.

After the end of the Mexican-American War, Governor Barbachano appealed to Mexican President
José Joaquín de Herrera for help in suppressing the revolt, and in exchange Yucatán again recognized the central government's authority. Yucatán was again reunited with Mexico on
17 August 1848.
