To understand the inner life and motivation of nobility members personal documents written by the nobles, such as their correspondence or diaries available in Czech archives, are of utmost importance. Irrespective of their unquestionable contribution to the research into the 20th century history of nobility such sources have been almost fully neglected by researchers in spite of the fact that Czech historiography had recognized the noble’s personal diary as an important source of historical information as early as the 1990s. Ego documents from the Kálnoky Family Archive largely extend our knowledge of how the nobility viewed the revolutionary events following the disintegration of Austria-Hungary and help us understand the motivation of their attitudes and behavior patterns in the first half of the 20th century.
