In the 13th century, royal privileges were granted to Bratislava. Significant period in life of the town at the turn of the 14th and 15th centuries was that of reign of Sigismund of Luxembourg. Sigismund confirmed earlier donations and privileges to the town granted by the ruling families of Arpads and Anjouos and, granting new privileges, he accentuated Bratislava as a prominent political and economic town of Hungary. Based on his decree of 1405, Bratislava ranked among the most significant towns that had been called royal towns since then. In 1434, he granted the town a heraldic deed with the right to use a coat of arms with three towers above an open gate in city walls.
