Ostroh Chronicler

The Ostroh Chronicler is not only a historical source, but also a monument of the Ukrainian language and literature.

The Ostroh Chronicler has survived in the only known manuscript entitled: From the Chronicles of Belsky's Collection of Necessities Selected, discovered by academician M. M. Tikhomirov in a codex in the museum collection of the State Historical Museum in Moscow and published by him in 1951 under the title Ostroh Chronicler.

This title is fully consistent with the content of the main part of the work, which focuses on the city of Ostroh (modern Rivne Oblast) and the events in Ostroh.

In this part of the chronicle, the author pays much attention to news concerning social relations between different segments of the population.

He is particularly interested in issues related to the Orthodox struggle against the Union of Brest (1596).
