**Dmytro Dedko** ([Ukrainian](/source/Ukrainian_language): Дмитро Дедько; [Latin](/source/Latin_language): *Demetrius Dedko*[1]) was a [Lord of Ruthenia](/source/King_of_Ruthenia) in 1340 (1323) – 1349. Commonly thought to be a [Galician](/source/Galicia_(Eastern_Europe)) [boyar](/source/Boyar), he could be one of sons of [Yuriy I](/source/Yuri_I_of_Galicia) and Varvara (Barbara). Dmytro is possibly the progenitor of [Ostrozky family](/source/Ostrogski_family).

## Life

Dmytro is mentioned in number of scientific works on history of that period such as "History of Ukraine-Ruthenia" by [Mykhailo Hrushevsky](/source/Mykhailo_Hrushevsky), "Die polnische Geschichtschreibung des Mittelalters" by [Heinrich Ritter von Zeissberg](/source/Heinrich_Ritter_von_Zeissberg) and others. The Russian historian [Alexander Presnyakov](/source/Alexander_Presnyakov) argues Hrushevsky's claims that Dmytro was representative of [Liubart](/source/Liubartas) in Galicia, rather in his declarations Dmytro states that Galician princes are his ancestors.[2]

Among the most solid historical benchmarks signed by Dmytro in 1341 is a document "Letter to residents of Torun" that survived to our days where he calls to revive economical and social relationships between the city of [Toruń](/source/Toru%C5%84) and [Halychyna](/source/Halychyna).

During the [Polish-Hungarian aggression](/source/Galicia%E2%80%93Volhynia_Wars) against the Kingdom of Ruthenia, Dmytro successfully defended his territory, serving simultaneously as a vassal of three rulers: [Lithuanian](/source/Lithuanians) [Liubartas](/source/Liubartas), [Casimir the Great](/source/Casimir_the_Great) and [Louis I of Hungary](/source/Louis_I_of_Hungary). Nevertheless, in 1344-1345 Casimir succeeded in annexing [Sanok](/source/Sanok).[3]

With the death of Dmytro and agreement with the Khan of [Golden Horde](/source/Golden_Horde) [Janibeg](/source/Janibeg), Casimir occupied Halychyna in 1349. In return for the Halychyna occupation, Poland promised a tribute to [Golden Horde](/source/Golden_Horde).

## Dmytro, son of Yuriy

Ukrainian writer Volodymyr Bilinsky argues that Dmytro Dedko is not a "Galician boyar", but rather a true Lord of Ruthenia and a son of [Yuriy I of Galicia](/source/Yuri_I_of_Galicia). Bilinsky also claims that Dmytro is a father of [Danylo Ostrozky](/source/Danylo_Ostrozky).

The writer also says that in the Kingdom of Ruthenia there was a [diarchy](/source/Diarchy) where one ruler governed in [Volhynia](/source/Volhynia), while another governed in [Halychyna](/source/Halychyna). Bilinsky states that Dmytro governed Halychyna not since 1340, but rather 1323 after the death of both Andriy and Yuriy II and along with Yuriy-Boleslav Troidenovych ([Bolesław Jerzy II of Mazovia](/source/Yuri_II_Boleslav)).
