The effects of the Treaty of Trianon on the pharmaceutical network

The consequences of the border adjustments resulting from the Treaty of Trianon affected the entire Hungarian pharmaceutical network. Transylvania, Maramureș and East Banat became part of Romania and Hungary lost 102.813 km2 of its former territory. A Hungarian population of 1,662,000 (based on the 1910 census), 31.78% of the total population, came under Romanian rule. 477 Hungarian pharmacies were lost in 327 locations. Later, in the areas given to Romania, several pharmacies ceased to function due to the emigration of their owners and their staff. Romanian authorities issued 174 new pharmacy rights in the gained territories, bringing 65.5% of the pharmacies into Romanian hands. The Pocket Calendar of Pharmacists, published in Budapest in 1918 still lists the Transylvanian pharmacists, mentioning the name of their pharmacy and the place where they worked. Pharmacist almanacs (pocket calendars) published in later years no longer provided this information.
