1918–1938 CzechoslovakiaČeskoslovensko

The Habsburg monarchy collapsed in 1918 and Hronsek became part of Czechoslovakia, a state in which Slovak was suddenly an official language and Slovak schools opened everywhere. The village stayed small and agricultural, but it sat on the road and the railway between two growing towns, Zvolen and Banská Bystrica, and people began travelling to work instead of farming at home. The wooden church, which for two hundred years had been a monument to what Lutherans were forbidden to do, started to be looked at as architecture.Habsburská monarchia sa v roku 1918 rozpadla a Hronsek sa stal súčasťou Československa — štátu, v ktorom sa slovenčina zrazu stala úradným jazykom a slovenské školy vznikali všade. Obec zostala malá a roľnícka, ležala však na ceste aj na železnici medzi dvoma rastúcimi mestami, Zvolenom a Banskou Bystricou, a ľudia začali za prácou dochádzať namiesto toho, aby gazdovali doma. Na drevený kostol, ktorý dvesto rokov pripomínal, čo evanjelici nesmeli, sa začalo hľadieť ako na architektúru.
