Mojmír II

Mojmír II (c. 871 - c. 933), was the eldest son of Svatopluk I and the second king of Great Moravia, succeeding his father upon his sudden death in 894 on the eve of the Magyar conquest of the Carpathian Basin. During his reign, Moravia lost the control of many territories which were conquered by Svatopluk, including Lusatia, Bohemia or the lands of the Vistulan tribes. However, he successfully defended the eastern borders of his realm, defeating the Magyars in the Battle of Preslava in 907.

In 911, upon consolidation of power in the remaining dependencies of Moravia, namely Nitra and Pannonia, Mojmír reverted the country back to the Slavonic rite, hoping that Moravia would once again become the center of Slavic culture it was during the reign of Rastislav. Despite his effort, the Bulgarian Empire remained the center and Mojmír's conversion only further disrupted Moravia's relations with the Franks.
