This essay is part of a 50-state series about the nation’s constitutions. We’ve asked an expert from each state to dive into their constitution, narrate its history, identify its quirks, and summarize its most essential components for our readers. In 1848, voters in the Wisconsin Territory ratified the Wisconsin Constitution that is still in use today. This founding document, amended more than 150 times, reflects the work of generations of legislators, advocates, and voters on topics from democracy to finance to individual rights.
