[5] Komarno, which until the Partitions of Poland belonged to Ruthenian Voivodeship, received its town charter (Magdeburg rights) in 1471 from King Kazimierz Jagiellonczyk.

The town was under protection of Voivode Stanislaw de Chodecz, who in 1473 founded here a Roman Catholic church.

In 1590, it belonged to Jan Ostrorog, the voivode of Poznań, and in the 17th century, it was property of the House of Wiśniowiecki.

On 8 October 1672 the Battle of Komarno took place here, in which King Jan III Sobieski destroyed a 10,000 strong Tatar unit.

In 1992, Ukrainian government returned the complex to the faithful, but soon afterwards, it was handed over to the local Greek-Catholic community.

Among people associated with Komarno are Jan Kilarski (mathematician), Countess Karolina Lanckoronska, linguist Roman Laskowski, historian Jozef Leszczynski, and writer Karol Szajnocha.
