Abstract
After Kazakhstan's independence, studying historical examples of constitutionalism became relevant. This study analyzes the development of constitutionalism in Kazakhstan's statehood. Using general scientific methods, it was found that constitutionalism has a long history in Kazakhstan. The origins trace back to the Kazakh Khanate laws of the 17th-18th centuries, with significant development during the 1917-1920 Alash Orda period. The decisions of the 1917 All-Kazakhstan Congresses were constitutionally significant. The study's practical significance lies in its relevance to modern Kazakhstan's democratic development.
