 Bona's sway over the king and the magnates, her efforts to strengthen the monarch's political position, financial situation, and especially the measures she took to advance her personal and dynastic interests, including the forced royal election of the minor Sigismund Augustus in 1529 and his premature coronation in 1530, increased the discontent among "szlachta" activists.The opposition middle "szlachta" movement came up with a constructive reform program during the Kraków sejm of 1538/1539.Among the movement's demands were termination of the kings' practice of alienation of royal domain, giving or selling land estates to great lords at the monarch' discretion, and a ban on concurrent holding of multiple state offices by the same person, both legislated initially in 1504.
