His area of service was the region of Bačka, which at the time was a southern part of Austria-Hungary, and he served in villages with numerous Croat inhabitants.
He early joined Illyrian movement, (Croatian national revival) along with Bačka Croats and Ivan Antunović.
[clarification needed] On September 22, 1919 he was a participant of the delegation of Bunjevci that went to Paris on conference to talk with foreign diplomats.
Greater Hungarian circles couldn't forgive him his struggle for separating Bačka and merging it to unified South Slavic state.
He was the editor of the Croatian-language magazine from Subotica, Naše novine, the organ of Land's Christian Socialist Party (Zemaljska kršćansko-socijalna stranka).
When he was in Zagreb April 23, 1939, leading the 50 deputies of Bunjevci and Šokci from Bačka, he said (and next day it was in Hrvatski dnevnik newspaper): ”Bunjevci i Šokci u Bačkoj... priznaju se za česti i uda onoga naroda koji živi u Međimurju, u Zagorju, u Lici pod Velebitom, na Hrvatskom Primorju, koji s nama isti jezik govori, najvećim dijelom istu vjeru ispovijeda, odgojen na grudima iste kulture, iz koje je ustao Ante Starčević i Stjepan Radić.

Ne samo voljom, već i svim silama nastojat ćemo da... svi mi Bunjevci ostanemo, što smo od iskona bili, Hrvati Bunjevci u sklopu današnje države...".
