Anny (St.Anna-Gymnasium) in Kraków and Jagiellonian University, where he graduated in 1913, receiving the degree of Doctor of Philosophy for a dissertation about the history of the Polish monetary system.

In 1914 he started work as teacher in Stanisławów (now Ivano-Frankivs'k, Ukraine), but after the 1st World War broke out he was mobilized into the Austro-Hungarian Army in the rank of Sub-Lieutenant, served on the Eastern Front and was wounded.

During this time he also joined the "Zet" association, an elite political society with historical roots in the National League (Narodowa Demokracja), but after 1914 linked rather with Józef Piłsudski and future Sanacja.

In 1926, when Piłsudski came to power (by a coup d'état of a part of the Polish army), Grażyński was appointed voivode of the Silesian Voivodeship.

Grażyński was one of the prominent leaders of the Związek Naprawy Rzeczypospolitej (Union for Improvement of the Republic), which was the left wing of Sanacja.
