What year was the current Missouri Constitution adopted?

The current Missouri Constitution was adopted in 1945, making it the fourth constitution of the state. This constitution was established to address various changes and developments that had occurred since the previous constitution adopted in 1875, which needed updates to reflect modern governance, including adjustments in powers, responsibilities, and rights. The 1945 Constitution introduced significant reforms and was designed to enhance the efficiency of state government and to protect the rights of citizens more comprehensively.

Understanding the historical context in which the 1945 Constitution was adopted is important, as it marked a pivotal shift toward a more structured and organized state government, responding to the needs of a growing and evolving populace. This makes the choice of 1945 as the year of adoption not just a detail of Missouri's governance but also a reflection of a broader trend in American state constitutions during that era, where many states sought to modernize and clarify their governing documents.
