Pedro Gallego

He was the first bishop of Cartagena from the diocese's restoration in 1248 until his death, and played a prominent role in organizing the church in the region of Murcia after 1243.

According to the 18th-century historian Pablo Manuel Ortega, his birthplace was Santa Marta de Ortigueira and his father was Gonzalo Pérez Gallego.

According to Juan Gil de Zamora, he joined the convent of La Bastida in Toledo under the superior Alfonso Martínez shortly after its founding in 1219.

[2][4] The city of Cartagena submitted to Castilian rule in 1244 and Pope Innocent IV restored its bishopric,[4] which had been vacant for over two hundred years, the last reference to a bishop being from 988.

[3] In Lyon, Pedro also obtained independence for his church from the metropolitanates of Toledo and Tarragona through the bull Novella plantatio Carthaginensis, making Cartagena subject directly to the Holy See.

[3][5] In 1265, on account of the revolt of the Mudéjares, Pedro had to abandon the city of Cartagena and take refuge in the countryside, only returning after James I of Aragon had crushed the rebels and conquered Murcia.

Since then José Martínez Gázquez has discovered the rest of this work in a Spanish manuscript, now Biblioteca Nacional de España, MS 8918.
