What significant change was made in the First Revision of the Constitution in 1850?

The significant change made in the First Revision of the Michigan Constitution in 1850 was the provision for a uniform rate of taxation. This change aimed to ensure fairness and equity in property taxation across the state, obligating authorities to impose the same tax rate on all properties of similar value. By establishing this uniformity, the intention was to prevent disparities in tax burdens that could arise from varying local tax rates, thereby promoting a more consistent and reliable taxation system throughout Michigan.

The other options reflect different tax-related concepts but do not accurately represent the essential reforms introduced in the 1850 revision. For instance, the introduction of income tax, establishment of local government, or elimination of property taxation did not specifically stem from this constitutional revision. Instead, the focus was primarily on creating a standardized approach to taxation, laying the groundwork for a fairer and more organized taxation system in the state.
