John X, Pope
JOHN X, POPE
Pontificate: March or April 914 to May or June 928;b. John of Tossignano, Romagna. Bishop of Bologna and archbishop of Ravenna, c. 905 to 914. John owed his office to the family of theophylactus; but the account of liutprand of cremona, suggesting an affair with the influential theodora, wife of Theophylactus, as the cause of John's preferment, is improbable. John was determined to rid southern Italy of the Saracens, and to this end formed an alliance between the Byzantine Emperor constantine vii, Berengar I (whom he crowned as emperor December 915), and other Italian princes. In the campaign that followed, the pope himself took part, and by August 915 the Saracens had been driven from their stronghold on the Garigliano River. During the difficult years of his pontificate, John strove to establish the temporal authority of the Holy See. He approved the strict rule of cluny, which had just been founded (910), and promoted the conversion of the Normans and the interests of the Church in Spain and the Slavic areas. He sent legates to the Synod of Hohenaltheim (916), which prepared the way for the close union of Church and State in Germany. He unfortunately approved of Hugh, the five–year–old son of Count Heribert, as archbishop of Reims in order to secure the release of King Charles the Simple, whom Heribert held in prison. A schism between Rome and Constantinople over the allowing of marriage for the fourth time ended during his pontificate. Whether John conferred the imperial title on Simeon, Czar of Bulgaria (893–927), is uncertain. John's pontificate ended in tragedy. After the murder of Berengar in 924, the pope formed an alliance with King Hugh of Italy, thus arousing the enmity of marozia, daughter of Theophylactus and Theodora. John was deposed and imprisoned in April 928, and afterward smothered by order of Marozia.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
