What year was the current Illinois Constitution adopted?

The current Illinois Constitution was adopted in 1970. This document replaced the previous 1870 Constitution and was crafted to address various needs and concerns that had arisen over the past century, updating the framework for state government and enhancing the rights of citizens.

The 1970 Constitution included significant reforms, such as home rule for local governments, the establishment of a Bill of Rights, and mechanisms aimed at improving the efficiency and accountability of government. The adoption of this Constitution was the result of a constitutional convention that was held specifically to revise the outdated 1870 document. This revision represented a significant shift in the governance of Illinois and reflects the evolving needs of its residents during that period.

The other years listed do not correspond to the adoption of the current Illinois Constitution, as they either pertain to earlier or later events in the history of the state's governance.
