Province of Upper Silesia
On 12 March 1933 Brückner became "Provinzial-Landtagsabgeordneter, Kreistagsabgeordneter" and "Stadtverordneter". On 25 March 1933 he was named to the Prussian State Council ("Preußischen Staatsrat") and became the acting "Oberpräsident" of the Prussian Province of Lower Silesia (made permanent on 2 August). On 29 May he was similarly named acting "Oberpräsident" of the Prussian Province of Upper Silesia (made permanent on 1 June). He thus united under his control the highest party and governmental offices in the two provinces. On 7 October 1933 he was promoted to "Gruppenführer" in the "Sturmabteilung" (SA).
