Pershing was born on a farm near Laclede, Missouri, to businessman John Fletcher Pershing and homemaker Ann Elizabeth Thompson. Pershing's great-great-grandfather, Frederick Pershing, whose name originally was Pfersching, emigrated from Alsace, leaving Amsterdam on the ship Jacob, and arriving in Philadelphia on October 2, 1749. Pershing's mother was of English descent. He also had five siblings: brothers James F. (1862-1933) and Ward (1874-1909), and sisters Mary Elizabeth (1864-1928), Anna May (1867-1955) and Grace (1867-1903); three other children died in infancy.
Spanish- and Philippine-American wars
At the start of the Spanish-American War, First Lieutenant Pershing was the regimental quartermaster for the 10th Cavalry; he fought on Kettle and San Juan Hills in Cuba, and was cited for gallantry. In 1919, he was awarded the Silver Citation Star for these actions, and in 1932 the award was upgraded to the Silver Star decoration. A commanding officer here commented on Pershing's calm demeanor under fire, saying he was "cool as a bowl of cracked ice.". Pershing also served with the 10th Cavalry during the siege and surrender of Santiago de Cuba.  Pershing was commissioned as a major of United States Volunteers on August 26, 1898, and assigned as an ordnance officer. In March 1899, after suffering from malaria, Pershing was put in charge of the Office of Customs and Insular Affairs which oversaw occupation forces in territories gained in the Spanish-American War, including Cuba, Puerto Rico, the Philippines, and Guam. He was honorably discharged from the volunteers and reverted to his permanent rank of first lieutenant on May 12, 1899. He was again commissioned as a major of Volunteers on June 6, 1899, this time as an assistant adjutant general.  When the Philippine-American War began, Pershing reported to Manila on August 17, 1899, was assigned to the Department of Mindanao and Jolo, and commanded efforts to suppress the Filipino Insurrection. On November 27, 1900, Pershing was appointed Adjutant General of his department and served in this posting until March 1, 1901. He was cited for bravery for actions on the Cagayan River while attempting to destroy a Philippine stronghold at Macajambo.  Pershing wrote in his autobiography that "The bodies [of some Moro outlaws] were publicly buried in the same grave with a dead pig." This treatment was used against captured juramentado so that the Moro would believe they would be going to hell. Pershing added that "it was not pleasant [for the Army] to have to take such measures". Historians do not believe that Pershing was directly involved with such incidents, or that he personally gave such orders to his subordinates. Letters and memoirs from soldiers describing events similar to this do not have credible evidence of Pershing having been personally involved. Similarly, the claim made by Donald Trump during his presidential campaign in February 2016 that Pershing executed 49 "Muslim terrorists" with bullets dipped in pig's blood, then let the 50th go free to spread the word about the religious atrocity, which Trump alluded to again while serving as president in August 2017, has been repeatedly debunked by historians, who find no evidence that such an incident occurred.  On June 30, 1901, Pershing was honorably discharged from the Volunteers and he reverted to the rank of captain in the Regular Army to which he had been promoted on February 2, 1901. He served with the 1st Cavalry Regiment in the Philippines. He later was assigned to the 15th Cavalry Regiment, serving as an intelligence officer and participating in actions against the Moros. He was cited for bravery at Lake Lanao. In June 1901, he served as Commander of Camp Vicars in Lanao, Philippines, after the previous camp commander had been promoted to brigadier general.
