During the reign of Zog primary education became necessary. Despite meager educational opportunities, literature flourished in Albania between the two world wars. Substantial progress had been achieved in literature, and art publishing operations. Distinguished writers included: Fan Stilian Noli, Alexander Drenova, Esad Mekuli, Ndre Mjeda, Haki Stermilli, Lasgush Poradeci, Faik Konica, Sterjo Spasse, Ndoc Nikaj, Foqion Postoli, Migjeni and others. A Franciscan priest and poet, Gjergj Fishta, dominated the literary scene with his poems about the Albanians' perseverance during their quest for freedom. During this period 600 night schools were opened in an attempt to eradicate illiteracy, but in 1939 80% of the adult population was still illiterate.
