Political parties are indispensable elements of democratic life. In connection with the vital importance of political parties for democratic life, it should be accepted that the regulations regarding their own internal order processes are very important. The most important document in terms of internal order transactions of political parties is undoubtedly the statutes of political parties. Although the statutes of political parties are related to the internal functioning of the legal entity of the political party, they are one of the important tools in which the political party gives a message to its stakeholders and voters regarding the social order it considers. In the study, the concept of political party statutes, which is the subject of limited study in the doctrine, is discussed in a way that covers the pre-period of 1924 Constitution. In the study, first of all, the concept of political party statute is discussed with a critical perspective. A periodic distinction was made in order to ensure that the subsequent political party statutes were analyzed systematically. The structural and functional aspects of the statutes of political parties that came into force before the 1924 Constitution, which is the first part of this periodical distinction, are presented in the study.
