Radziwiłł Chronicle

The Radziwiłł Chronicle, also known as the Königsberg Chronicle, is a collection of illuminated manuscripts from the 15th-century; it is believed to be a copy of a 13th-century original. Its name is derived from the Radziwiłł family of the Grand Duchy of Lithuania (later, the Polish–Lithuanian Commonwealth), who kept it in their Nesvizh Castle in the 17th and 18th centuries. The Radziwiłł manuscript was taken out of Königsberg in 1761 and acquired by the Library of the Russian Academy of Sciences, Saint Petersburg, where it is currently preserved with registration number "34.5.30".

The work tells the history of Kievan Rus' and its neighbors from the fifth to the early 13th centuries in pictorial form, representing events described in the manuscript with more than 600 colour illustrations. Among East Slavic chronicles, the Radziwiłł is distinguished for the richness and quantity of its illustrations, which may derive from the 13th-century original. The chronicle includes the Tale of Bygone Years and extends it with yearly entries until 1206.
