Failure of the eastern planter elite to make constitutional reforms exacerbated existing east–west sectionalism in Virginia and contributed to Virginia's later division. The Virginia Constitutional Convention of 1850–51, the Reform Convention, addressed a number of issues important to western Virginians. It extended the vote to all white males 21 years or older. The governor, lieutenant governor, the judiciary, sheriffs, and other county officers were to be elected by public vote. The composition of the General Assembly was changed. Representation in the house of delegates was apportioned on the basis of the census of 1850, counting whites only. The Senate representation was arbitrarily fixed at 50 seats, with the west receiving twenty, and the east thirty senators. This was made acceptable to the west by a provision that required the General Assembly to reapportion representation on the basis of white population in 1865, or else put the matter to a public referendum. But the east also gave itself a tax advantage in requiring a property tax at true and actual value, except for slaves. Slaves under the age of 12 years were not taxed and slaves over that age were taxed at only $300, a fraction of their true value. Small farmers, however, had all their assets, animals, and land taxed at full value. Despite this tax and the lack of internal improvements in the west, the vote was 75,748 for and 11,063 against the new Constitution. Most of the opposition came from delegates from eastern counties, who did not like the compromises made for the west. Given these differences, many in the west had long contemplated a separate state. In particular, men such as lawyer Francis H. Pierpont from Fairmont, had long chafed under the political domination of the Tidewater and Piedmont slave-holders. In addition to differences over the abolition of slavery, he and allies felt the Virginia government ignored and refused to spend funds on needed internal improvements in the west, such as turnpikes and railroads. West Virginia was the only state in the Union to separate from a Confederate state (Virginia) during the American Civil War. In Richmond on April 17, 1861, the Virginia Secession Convention of 1861 voted to secede from the Union, but of the 49 delegates from the northwestern corner (which ultimately became West Virginia) only 17 voted in favor of the Ordinance of Secession, while 30 voted against (with two abstentions). Almost immediately after that vote, a mass meeting at Clarksburg recommended that each county in northwestern Virginia send delegates to a convention to meet in Wheeling on May 13, 1861.
