Baran was first mentioned in 1470 and chartered in 1598 by Krzysztof Radziwiłł.

From the 1730s the proprietor was Franciszek Maksymilian Ossoliński, and later Michał Kazimierz ("Rybeńko") Radziwiłł, who reconstructed the palace in the rococo style, probably to a design by Johann Sigmund Deybel.
He is said to have accorded a hospitable reception to the Polish prince Mikołaj Krzysztof "the Orphan" Radziwiłł when the latter visited Padua.

It is likely that Mikołaj "the Black" Radziwiłł's wooden Vilnius mansion was on the same site, but the current building was constructed by the order of Janusz Radziwiłł from 1635 until 1653, according to the design by Jan Ullrich.
Between 1718 and 1721 the trompe-l'œil altars of St. Casimir and Virgin Mary were sponsored by Michał Kazimierz Radziwiłł, voivode of Vilnius.
Struggling between his Polish subjects and the Prussian authorities, Radziwiłł found himself with little power, as effective power was executed by Oberpräsident Joseph Zerboni di Sposetti and the district governors heading the Regierungsbezirke of Posen and Bromberg.
Apart from the guitar, cello and opera concertos performed by Radziwiłł himself, among his guests were Niccolò Paganini (concert in Poznań on 19 May 1829), Johann Wolfgang von Goethe, Frédéric Chopin and Ludwig van Beethoven.
Together with his cousin Janusz Radziwiłł in 1654 during The Deluge, or Swedish invasion of Poland, Bogusław Radziwiłł began negotiations with King Charles X Gustav of Sweden aimed at breaking the Commonwealth and the Polish–Lithuanian union.
The manuscript once belonged to the polish high noble family Radziwiłł — like ℓ 34 — hence name of the codex.
His father Hieronim Mikołaj Radziwiłł was deported to a Gulag during the Soviet occupation of Poland and died on 6 April 1945.
Most likely he went there with the powerful Lithuanian-Polish Radziwiłł family.
In February 1945, the Radziwiłł family was deported by the NKVD to a labour camp in Krasnogorsk.
