Leon Michał Przyłuski (1789–1865) was a Polish Roman Catholic Bishop who was Archbishop of Gniezno and Primate of Poland[1] from 1845 to 1865.

Przyłuski was born in 1789 (probably on October 5) in Strzeszynku, to father, Stanisław (1747-1843) of the Lubicz noble family and his mother Sarah Wal (1750-1848).

[5] As a bishop, he advocated for representation of Polish national to the Prussian Government.

In January 1846, the Prussian government forced him to make an announcement denouncing the Wielki Poland Uprising, but in March 1848, he stood at the head of the deputation to the Prussian King concerning the maintenance of the autonomy of the Grand Duchy of Poznań.

[6] His support for the uprisings of the early 1860s caused the authorities to approach the Vatican in 1862 to seek the removal of Przyłuski as archbishop.
