モラヴィア王国
As mentioned above, in 900 the Magyars invaded Transdanubia (a former Great Moravian territory occupied by Franks) and raided Bavaria together with Mojmir’s troops. Eastern Francia was compelled to conclude a peace treaty with Great Moravia in 901 and Mojmir was reconciled with his brother, who is assumed to have returned to Great Moravia about this time. The peace treaty with the Eastern Franks also put an end to wars between Great Moravia and the Frankish vassal Bohemia lasting since 895. When and whether the territory that is now southern Poland seceded from Great Moravia is unknown.
