The Second Reform Act of 1867 was the second of two major reforms passed by Parliament in the 19th century. While the First Reform Act of 1832 proved that change was indeed possible, there was still much to be done to the social, political, and economic landscape of Britain. The Second Reform Act notably expanded voting rights for British citizens. The Act was largely beneficial to working-class men and landowners, as it enfranchised all household owners and lodgers who paid rent of > £10 a year as well as reduced the property threshold so that agricultural landowners and tenants with very small amounts of land might also be given the right to vote. J.S. Mill was a strong proponent of women's suffrage and, as a member of Parliament, was staunch in his position to amend the act in favor of including women in its list of enfranchised citizens. His efforts were in vain and Mill soon left Parliament entirely in 1868.
