Please answer the following question: Information:  - Bullfighting (or ; or ), also known as tauromachia or tauromachy (, ; from "bull-fight"), is a traditional spectacle of Spain, Portugal, parts of southern France and some Latin American countries (Mexico, Colombia, Ecuador, Venezuela and Peru), in which one or more bulls are fought by humans in a bullring. Although it can be defined as a blood sport, within the areas where it is practiced it is not considered a sport. Instead, it is considered a highly ritualized cultural event and art form which some see as deeply tied to Spanish culture and identity.  The bullfight, as it is practiced today, involves professional "toreros" (of whom the most senior, who actually kills the bull, is called a matador) who execute various formal moves which have a meaning, or at least a name, according to the bullfighter's style or school. It has been alleged that toreros seek to elicit inspiration and art from their work and an emotional connection with the crowd transmitted through the bull. The close proximity places the bullfighter at risk of being gored or trampled by the bull. After the bull has been hooked multiple times behind the shoulder by other toreros in the arena, the bullfight usually concludes with the killing of the bull, ideally by a single sword thrust, which is called the "estocada". Sometimes, the life of the bull is spared due to his braveness ("indulto"); once the animal has been treated, it is returned to live in the dehesa. Such pardons are nevertheless rare. In Portugal, the finale consists of a tradition called the "pega", where men ("forcados") try to grab and hold the bull by its horns when it runs at them.  - Rejoneador (pl. "rejoneadores"; "lancer") is the name given to a bullfighter who fights the bull on horseback. The "rejoneador" should not be confused with the "picador", who is just an assistant of the matador. The "rejoneo" is a form of bullfighting in Portugal and in Spanish bullfighting.  - A subaltern is a primarily British military term for a junior officer. Literally meaning "subordinate", subaltern is used to describe commissioned officers below the rank of captain and generally comprises the various grades of lieutenant.  - "Torero" or "toureiro" (both from Latin "taurarius", bullfighter) is the Spanish word for bullfighter and describes all the performers in the sport of bullfighting as practised in Spain, Portugal, Mexico, Peru, France and other countries influenced by Spanish culture. The performers who participate in the bullfight include: the main performer, who is the leader of an entourage and the one who kills the bull and is addressed as "maestro" (master), or with the formal title "matador de toros" (killer of bulls); the other bullfighters in the entourage are called "subalternos" and their suits are embroidered in silver as opposed to the matador's more-theatrical gold, and include "picadores", "rejoneadores", and "banderilleros".   - Ernesto Pastor Lavergne ( 4 April 1892 - June 11 , 1921 ) was the first , and so far only , Puerto Rican - born bullfighter ( torero ) to gain international fame .
