Monitor was founded in March 1765 by Ignacy Krasicki and Franciszek Bohomolec, with active support from King Stanisław August Poniatowski. It came out weekly, later semi-weekly. Its title was a tribute to the "small" Monitor published by Prince Adam Kazimierz Czartoryski.

Inspired by the English Spectator and the spirit of rationalism and religious tolerance, Monitor has contributed to a negative view of the Polish–Lithuanian Commonwealth under the Wettin dynasty. The Monitor advocated reforms and criticized a degenerate Sarmatian culture and the abuses of "Golden Liberty."
