In the 9th century,
Mosapurc or
Moosburg was a fortified settlement built along the
Zala river and was the capital of the Frankish vassal
Lower Pannonian Principality ruled by a Slavic prince
Pribina (
"Privinae civitas, munimen, castrum in nemore et palude Salae" in a
Salzburg chronicle). During the reign of Pribina's son, prince
Kocel (861–876), in the summer of 867, it provided short-term hospitality to brothers
Cyril and Methodius on their way from
Great Moravia to the pope in
Rome to justify the use of the
Slavonic language as a liturgical language. They and their disciples turned Blatnograd into one of the centers that spread the knowledge of the new
Slavonic script (
Glagolitic alphabet) and literature, educating numerous future missionaries in their native language.
Battle of Pressburg It is claimed that
Urbs Paludarum, Brazlavo's burg (Moosburg), was the site of the
Battle of Pressburg, instead of
Bratislava. The only contemporary source mentioning a location of the battle is the
Annales iuvavenses maximi (Annals of Salzburg); however, the reliability of these annals is questionable, as they survive only in fragments copied in the 12th century. According to the annals, the battle took place in the vicinity of Brezalauspurc, the castle of Duke Brazlavo (
Braslav), located west of
Lake Balaton. ==Gallery==
