For centuries, Croatia and Croatian people were politically connected with Austria. The beginnings of political relations date back to the year 1527, when citizens of the then Kingdom of Croatia elected Austrian Kaiser Ferdinand the 1st to be their king. Other regions inhabited by Croats (for instance Slavonia, which was occupied by the Turks, and Dalmatia, Dubrovnik and Istria, occupied by Napoleon and Venice) joined that union after wars for liberation. They founded the Triune Kingdom of Croatia, Slavonia and Dalmatia and maintained political unions with Austrians to live under the Austrian crown up to 1918. Political and administrative connections influenced language contacts. Those language contacts at different historical times varied from strong, but partial German influence to gradual and later complete acknowledgement of equality of all languages. Some linguists suggest that German language influences were stronger in the administrative sphere than they actually were (Mamić, 1992: 15), because Latin was the official language in Croatia until 1847. Nevertheless, one should not neglect the fact that at the time of the Austrian Empire, German was the dominant language in the Croatian education system and in many domains of social and economic life (Kordić, 2003). In the mid 19th century, when national idealism movements spread all over Europe, Croatian language became the official language in Croatia as a constituent political entity of the Austro-Hungarian Kingdom. However, German language influences were obvious and inevitable in many fields. This paper will focus on exploration of those influences on legal phraseology. To achieve exactness and scientific reliability in our findings, the research is restricted to the field of criminal procedure law. Further, our project explores phraseology of historical texts of Austrian and Croatian Criminal Procedure Codes published in the 19th
