His grandfather Francisco is credited with advancing the art of using the muleta; his father and two brothers were also toreros.

As a youth he participated in bullfights in Algeciras and in Seville in 1772; and in Madrid, with his father and Costillares, in 1775.

Although the school lasted only from 1830 to 1832, it had an enormous influence where Romero offered his knowledge to matadors-in-training.

[2] He is credited with the invention of the classical style of bullfighting in the School of Ronda and Pedro Romero's name is inseparable from the Plaza de Toros (bullring).

[3] He killed numerous bulls in a bullring in Madrid at the age of eighty, probably the last corrida he fought.
