Gheorghe Grigorovici was born in May 1871 old style in the town of Storojineț in Duchy of Bukovina, then an Imperial province of Austria-Hungary (today in Ukraine).

In 1907, in Austria's first elections based on universal and equal votes, Grigorovici became the first Romanian Social-Democrat deputy in the Vienna Parliament.

"[3] After the Great Union in December 1918, it became necessary to unify the socialist and social-democratic movements in Transylvania, Banat, Bukovina, Bessarabia, and the Old Kingdom.

The lack of ideological unity has led to conflicts: "the Social Democrat George Grigorovici, autodeclared enemy of Russian and Hungarian Bolshevism" (as described in a Comintern call of 27 March 1920) and other representatives of the Social Democracy refused to accept unification in a "Bolshevik" party affiliated to the 3rd International, an idea supported by the communists.

During the Royal dictatorship of King Carol II of Romania, he supported collaboration with the National Renaissance Front, as he was under state secretary at the Labor Ministry.
