The development of the Romanian elite in the duchy of Bukovina, between the second half of the 19th century and the beginning of the 20th century influenced to a great extent the evolution and the transformations of the native nationalism in the province. By the contribution of the progressive elements of the Romanians in Bukovina, as well as by the desire of most of the population to make democrat the public life, the national movement passed from a phase with cultural character to a stage mainly of political nature. Within this phenomenon, a decisive role was played by Iancu Flondor, a remarkable representative of the Romanians in Bukovina. About him and his contribution to the evolutions of the Romanians in Bukovina towards a political and party life in a modern meaning, as well as about his substantial contribution to the union of Bukovina and its integration into the structures of Great Romania, it was often written in a subjective or festive manner. In our historiographic approach we have centered upon a large amount of novel archive information of the Romanian, German, Ukrainian historians etc. During the first decades of the 20th century, the historiographic contributions related to Iancu Flondor had a fragmentary nature, centering mainly on his activity in the support of the union of Bukovina with Romania, some references about the genealogy of Flondor family, or about the elaboration of some concise pen portraits. Beginning with the ‘80s of the communist period, the efforts of the Romanian historians and researchers to acknowledge the past of Bukovina had intensified, amplifying and developing more and more. Among the most significant and valuable contributions of the present Romanian historiography concerning the development of the elite, the Romanian parties and the parliamentary government in Bukovina of the Habsburg period there are the papers, studies and articles of some known historians.
