King Alexander tried to reconcile political parties by unveiling a liberal constitution of his own initiative in 1901, introducing for the first time in the constitutional history of Serbia the system of two chambers ("skupština" and "senate"). This reconciled the political parties but did not reconcile the army which, already dissatisfied with the king's marriage, became still more so at the rumors that one of the two unpopular brothers of Queen Draga, Lieutenant Nikodije, was to be proclaimed heir presumptive to the throne.
