Ruch egzekucyjny (execution movement) of the late 16th century, led by Lord Grand Chancellor of the Crown Jan Zamoyski (against the interests of his own family), put as one of its goals the 'execution of lands', i.e. return of all Crown lands, which were often illegally held by next generations of Starostine families. In 1562–1563 they forced most of the Crown land in the Crown of the Polish Kingdom to be returned to the monarch, however later the whole cycle repeated. In the following centuries Ruch egzekucyjny (lit. "execution movement") and subsequently elected Kings were gradually weakened because szlachta achieved more and more privileges – the "Golden" Liberty.
