Teodor Burada, a Romanian ethnographer and folklorist that visited the region of Ćićarija to study the Istro-Romanian language, met the 12-year-old Glavina in 1893.

At the beginning of the 20th century, Glavina returned to Istria as a qualified teacher of the Romanian and Italian languages to teach at secondary schools, first in Parenzo (now Poreč) and then in Santa Domenica d'Albona (now Sveta Nedelja), where he remained until 1918.

[3] However, Austria-Hungary, partly due to the Croatian pressure, remained firm in its decision, so Glavina had to limit himself to advertising campaigns in local and national newspapers and failed contacts with deputies of the empire.

[3] At the same time, Glavina aimed to unify the Istro-Romanian villages in one single municipality south of the Učka mountain range, as the economic and social conditions there were bad.

After being named mayor, Glavina worked on the economic conditions of the municipality and planned the construction of a larger school, a road to connect with the Adriatic coast, a post office and a telegraph, among others.

[1] However, his greatest ambitions were to recover the Raša River basin (although this was previously proposed by Venice and Austria), which was completed in 1932, and the exploitation of a nearby semi-abandoned coal mine.
