Agustín de Iturbide, who is exiled in Europe, returns to Mexico. The Congress has issued a decree that declares the ex-emperor a traitor, and gives any person who sees him set foot in Mexico the right to put him to death. Iturbide arrives from England and disembarks in Soto la Marina, where he is recognized by Colonel Felipe de la Garza. The Colonel arrests him and informs him of the irrevocable order to execute him. Unaware of the decree, Iturbide has come back to warn the government of a possible invasion planned by the Holy Alliance, and persuades De la Garza to let him speak before the Congress of Tamaulipas. Before the caravan reaches the town of Padilla, word arrives that his request has been denied. Agustín de Iturbide, first Emperor of Mexico, is summarily executed. Three month later, Guadalupe Victoria is elected by Congress the first President of Mexico under a Federal Constitution. This is the birth of the Republic.
