In the 19th century, the Catholic Church in Poland was a form of Polishness. When the January Uprising broke out, activities of the Catholic clergy included pastoral care over insurgent troops, insurgent administration, participation in armed operations, and announcing of orders from insurgent authorities and information on insurgent activities from the pulpit. Piotrków clergy also joined the activities to support the uprising. In Piotrków, as in many other cities, priests preached independence sermons. The main share should be attributed to Piotrków nuns and monks who responded positively to the collection of national tax for the uprising. Conventions did not escape post-insurgent repression – they were dissolved.
