Pablo González Garza (1879-1950) was a Mexican General during the Mexican Revolution. He participated in Francisco Madero's insurrection against Porfirio Diaz in 1911. Subsequently, in 1912, he fought against the rebellion of Pascual Orozco. Later, after Victoriano Huerta's coup d'etat against Madero, González fought against Huerta and Pascual Orozco in Coahuila...

Later he was appointed chief of the Army of the Northeast in the government of Venustiano Carranza and in 1914 occupied Monterrey, Tampico and other places for him. González's occupation of Monterrey, along with the Battle of Zacatecas, was crucial in Huerta's defeat and subsequent decision to go into exile. At the same time, Alvaro Obregón was appointed to lead the Army of the Northwest, which was a position equivalent to that of González...González's occupation of Monterrey, along with the Battle of Zacatecas, was crucial in Huerta's defeat and subsequent decision to go into exile...He was also in charge of pacification of the Zapatista rebellion in Morelos during the fighting between Emiliano Zapata and Carranza, where he earned a reputation for brutality and ruthlessness. González' manifesto of July 19, 1916 explicitly stated that Morelos civilians, including women and children, who were perceived as supporters of Zapata, were going to be massacred (though officially counted among those who died in battle). In his pacification campaigns, González reinstitute the practice of Victoriano Huerta and Porfirio Diaz of shipping captured peasants to Yucatan for heavy forced labor. To combat González, Zapata decided to provide arms to individual villages, even those not directly under his control, so that they could form effective self defense units. This policy eventually back fired on Zapata as after González left, the villagers used the weapons against Zapatista foraging parties which in turn led to numerous conflicts between the peasants and the rebel troops that were supposed to represent their cause.

González was mostly successful in squashing the rebellion in Morelos for the time being, mostly because of help from a turncoat Zapatista general Sidronio Camacho (who had killed Zapata's brother, Eufemio) who provided him with crucial intelligence. However, after the break out of another revolt in Coahuila, led by Lucio Blanco, González was recalled and Zapata reclaimed his home state.

He was the mastermind behind the assassination of Emiliano Zapata, which was carried out by his Colonel, Jesus Guajardo. In early 1919 disagreements arose between González and Guajardo, and after learning of these, Zapata wrote a letter to Guajardo, asking him to join the Zapatistas. The letter was intercepted by González who blackmailed Guajardo and used it as an opportunity to set up an ambush for Zapata. Guajardo, after making a show of loyalty to Zapata by executing a turn coat Zapatista chief, Victoriano Barcena, arranged a meeting with Zapata at Chinameca Hacienda at which he was supposed to deliver badly needed ammunitions. After Zapata arrived,on April 10, 1919, a guard of honor presented arms to him, but on the third signal of the bugle they opened up fire at point blank range, killing Zapata.

In the election of 1920, President Carranza promoted the civilian Ignacio Bonillas as his successor, to the great displeasure of his generals, particularly Álvaro Obregón, who wanted the presidency for himself. After Carranza attempted to arrest him, Obregón led a military revolt.

Initially González remained loyal to Carranza. However, most officers in his army supported Obregón, and his ally, Plutarco Calles and vehemently opposed Bonillas. As a result González declared his own candidacy for the presidency. In April, Carranza demanded that González drop his election bid and give his full support to Bonillas. On April 30, González officially broke with Carranza [on May 4 he joined the Generals' rebellion] although instead of arresting Carranza and immediately occupying Mexico City (most of the troops in the region supported him), he allowed Carranza to escape to Veracruz and he himself withdrew to nearby Texcoco.

On April 8, 1920, a campaign aide to Obregón attempted to assassinate Carranza. After the failed attempt, Carranza was forced to flee Mexico City. [Carranza's infamous so-called Golden Train carrying the entire national treasury in the form of gold bars departed Mexico City May 7. The Golden Train had just cleared Mexico City when General Pablo González and his troops swept in and seized the capital.] Carranza set out towards Veracruz but was betrayed and assassinated in Tlaxcalantongo in the Sierra Norte de Puebla by the forces of General Rodolfo Herrero, supporter of Carranza's former allies, on May 21, 1920.
