Some thoughts:
Writing around the rim, starting at the 12:30 position, seems to be: Lacznosc--sila.
There is a town in Poland called Laczna and many villages with similar names beginning with the same letters. Perhaps the medal commemorates some event from that town.
In 1914 (the date on the medal, but not necessarily the date the medal was produced), Poland didn't exist as an independent state. Instead, that land was Prussian, Austrian (or Russian since about 1831). What triggered (no pun intended) Poland's independence was The Great War of 1914-18 (WWI). Not until (first) Germany proclaimed Poland as an independent kingdom in 1916, then later, when the Armistice was signed (1918) did Poland finally regain its status as an independent state. Bottom line: If the medal is Polish, I think it was produced after 1914; in 1916 or later, when they were independent.
