 Many Arians (such as Piotr of Goniądz and Jan Niemojewski) were pacifists opposed to private property, serfdom, state authority and military service; through communal living some had implemented the ideas of shared usage of the land and other property.A major Polish Brethren congregation and center of activities was established in 1569 in Raków near Kielce, and lasted until 1638, when Counter-Reformation had it closed.The notable Sandomierz Agreement of 1570, an act of compromise and cooperation among several Polish Protestant denominations, excluded the Arians, whose more moderate, larger faction toward the end of the century gained the upper hand within the movement.
