Aromanian language
In the early twentieth century Fier was populated by Orthodox Christians, most who spoke the Aromanian language and a small minority who spoke the Albanian language. Like most southern Albanian regions, the people of modern Fier mostly speak an Albanian Tosk dialect. Typical of southern Albanian cities, the population is mixed Orthodox and Muslim. Data shows that in 1918, just after independence from the Ottoman Empire, Fier and the surrounding countryside of the Myzeqe region formed a majority Orthodox Christian enclave, in which Muslims constituted roughly 35% of the population. Fier has been affected by emigration.
