Шварно Данилович: Литваның ғалымы және князі

Grand Duke of Lithuania from 1267 to 1269

Shvarn or Shvarno (; ; Шварно Данилович; c. 1230 – c. 1269) was the prince of Kholm from 1264 to 1269, and Grand Duke of Lithuania from 1267 to 1269. An influential leader, he became involved in internal struggles of power within the neighboring Grand Duchy of Lithuania.

Little is known of Shvarn and even his name is not entirely certain. The original documents relating to this ruler are scarce and mention him under a variety of names. For instance the first edition of Lithuanian Annals mentions him as Shkvarno, but the following editions use the names of Skirmont and Skirmunt, possibly a Ruthenisation of Lithuanian name Skirmantas. Contemporary sources also mention his Christian name of Ioann (Іоанн), that is either John or George. In modern times the ruler is known by a variety of names in various historiographies, including Lithuanian Švarnas, Ukrainian Шварно Данилович, Russian and Belarusian Шварн, and Polish Szwarno Daniłowicz. All of them are versions of the name of Shvarn, which is likely to be a diminutive of the Slavic name of Svaromir.

One of the sons of king Daniel I of Galicia of the house of Romanovich, Shvarn inherited the north western parts of the Kingdom of Ruthenia, his fathers' domain. This land included the town of Halicz itself, as well as the land across the Bug River, that is Red Ruthenia with the towns of Bełz, Czerwień, Mielnik, Drohiczyn and eventually also Kholm (since 1264). His brother Lev I inherited the southern part of the land, with the cities of Lviv and Przemyśl, while Roman became the heir of duchies of Lutsk and Terebovl. This allied him to Lithuania and together the two rulers undertook numerous military campaigns against the Kingdom of Poland. Already in 1255 they raided Lublin, in 1262 a major campaign against Masovia was started. Shvarn and Treniota captured the city of Płock and besieged Shvarn's brother in law, Siemowit I of Masovia in Jazdów (modern Warsaw). In the end Siemowit was killed by Shvarn's troops and his son Konrad II was taken prisoner. The Polish relief force did not arrive in time and was later defeated in a battle at Długosiodło on August 5, 1262. In 1264 king Daniel of Galicia died and Shvarn received nominal overlordship over all of Kingdom of Ruthenia as its duke. Immediately he mounted a major campaign against Poland, this time aiming for Lesser Poland. However, although joint armies managed to plunder Skaryszew, Tarczek and Wiślica, this time the campaign was less successful and the allied Ruthenian and Lithuanian armies were repelled. The Yotvingian auxiliaries were defeated by Bolesław V the Chaste at the Battle of Brańsk. and he probably did not gain a strong foothold in that country. However, he was apparently fairly successful in expanding his borders. Following successful military campaigns, in 1267 he defeated his brother Mstislav in the battle of the Yaselda River and captured Turov and Pinsk. and came under the control of Traidenis, a noble from Aukštaitija.
