Pancho Villa (August 1, 1901 - July 14, 1925) was the nome de guerre by which the legendary Filipino flyweight boxer Francisco Guilledo was best known. Villa, who stood only 5 feet tall and never weighed more than 114 pounds, rose from obscurity to win the World Flyweight boxing championship in 1923, earning acclaim in some quarters as "the greatest Asian fighter in boxing history".  Villa is also remembered to this day for the unusual, tragic, and rather needless circumstances surrounding his death at the young age of 23, while at the height of his boxing career.
Early life and Philippine boxing career
Guilledo was born in Ilog, Negros Occidental, the son of a cowhand who abandoned his family when Guilledo was just six months old. He grew up in the hacienda of a wealthy local, helping his mother raise goats she tended on the farm.
When Guilledo was 11, he sailed to Iloilo City to work as a bootblack. While in Iloilo, he befriended a local boxer, and together they migrated to Manila, settling in Tondo. He would occasionally spar with friends, and soon attracted the attention of local boxing habitues. He fought his first professional fight in 1919 against Kid Castro. Within two years, he was the Philippine flyweight champion, having dethroned "Terrible Pondong". He nearly gave up boxing after being spurned by a woman he courted, actually returning to Negros early in 1922 to retire. The clamor of Filipino boxing fans compelled him to return to the ring.
It appears that during this period, Guilledo was under the tutelage of at least two important local boxing figures. One was the American boxing promoter based in Manila Frank E. Churchill. Another was an Filipino ice plant executive and boxing manager named Paquito Villa. The renaming of Francisco Guilledo to Pancho Villa has been attributed to both men, depending on the source. One version tags Churchill as having renamed Guilledo into Villa, taking the name from the eponymous Mexican guerrilla leader.  Another version maintains that Paquito Villa had legally adopted Guilledo as early as 1918, renaming him Pancho.
World flyweight champion
In May, 1922, Villa received an invitation from famed boxing promoter Tex Rickard to fight in the United States. He accepted the invitation, and sailed to America together with Churchill and Paquito Villa. He immediately won his first overseas fight against Abe Attel Goldstein in Jersey City on June 7, 1922. He then fought and defeated Frankie Genaro on August 22, 1922. By this time, Villa had caught the attention of boxing aficionados, and he was slated to fight against the American flyweight champion Johnny Buff on September 15, 1922.
Villa defeated Buff in an upset, knocking out the champion in the 11th round to win the American flyweight championship. At this point, Villa had been in the American phase of his career for only 4 months. Villa lost the title early the following year to Genaro, who defeated the Filipino on points in a widely criticized decision. The unpopularity of Villa's defeat on points proved fateful. Jimmy Wilde, the Welsh-born boxer and former world flyweight champion had decided to end his recent retirement and seek the then vacant world flyweight championship in a fight to be staged in America. While Genaro, the US champion, seemed as the logical choice to fight Wilde, Villa's growing popularity soon convinced promoters that the Filipino would prove as the better draw.
Villa did not disappoint. On June 18, 1923, at the Polo Grounds in New York, Villa was cheered on to victory over Wilde by over 20,000 fans screaming "Viva Villa!" The win came by way of a knockout in the 7th round caused by a crashing right to Wilde's jaw. Villa was described as relentless, pummelling Wilde with both hands, and causing the Welshman to also drop in the fourth and fifth rounds. Wilde never fought again.
The new world flyweight champion successfully defended his title several times and never relinquished it until his death just two years later. Villa returned to a heroes welcome in Manila in September 1924, feted with a parade and a reception at Malacañan Palace. He also returned to his old haunts in Iloilo and his hometown in Negros. Before returning to the United States, he fought one more bout in Manila, against Clever Sencio, on May 2, 1925. Villa prevailed. None of the thousands of fans who saw that fight at Wallace Field knew that they had just witnessed Villa's final victory, and the second to the last fight of his life.
Villa returned to the United States to prepare for his next match, a non-title fight against Jimmy McLarnin scheduled for July 4, 1925, at Ewing Field in Oakland. Days leading to the fight, Villa's face became swollen due to an ulcerated tooth. According to contemporary newspaper accounts, on the morning of the fight, Villa went to a dentist to have the tooth extracted. Despite the pain and swelling, Villa insisted on going ahead with fight with McLarnin. Villa ended up spending most of the fight using one hand to protect his afflicted face. Given these circumstances, Villa naturally lost, though he managed to stay the distance. It was Villa's last fight.
Two or three days after the McLarnin fight, Villa had three more teeth extracted after an infection was discovered. Against his dentist's prescription of bed rest, Villa spent the next few days carousing with friends. Villa's condition worsened thereafter, and by July 13, 1925, he had to be rushed to the hospital. It was then discovered that the infection had spread to Villa's throat, resulting in Ludwig's angina. Villa was rushed into surgery, but he lapsed into a coma while on the table, and died the following day, July 14, 1925. He was only 23.
Villa's remains were returned to Manila, and in August of 1925, Villa was buried at Manila North Cemetery. He was survived by his wife, Gliceria.
Villa was inducted rather belatedly into the International Boxing Hall of Fame in 1994, the second Filipino boxer so honored after Flash Elorde, who was born 7 years after Villa's death. 33 years earlier, in October of 1961, Villa was added by Ring Magazine to its own boxing hall of fame.
Villa had a record of 73 wins (25 KOs), 5 losses, 4 draws, and 23 no decisions in a total of 105 fights.
He was commemorated in two tracks on Sun Kil Moon's acclaimed 2003 album Ghosts of the Great Highway, an album which seems fixated on themes of memory, past ghosts and those who died before their natural time.
