Its rapid diffusion can be seen in the use of a constitutional convention (instead of the existing Congress of the Confederation) in 1787 to revise the federal-level Articles of Confederation. The call in February of 1787 from the Congress said, “That it be recommended to the States composing the Union that a convention of representatives from the said States respectively be held for the purpose of revising the Articles of Confederation.”

31. During this period, seventeen state constitutional conventions were held (seven in the North and ten in the South). See Appendix Table A1 for conventions by each state.

35. Fehrenbacher, Don, Sectional Crisis and Southern Constitutionalism (Baton Rouge: Louisiana State University Press, 1995), 109Google Scholar, stated that “perhaps the outstanding feature of state constitutional development in the slave-holding South was its similarity to such developments elsewhere.”

36. While these democratizing reforms were due to many causes, one important factor driving their diffusion was the admission of six (three slave and three nonslave) frontier states between 1816 and 1821. None of these states enacted economic restrictions to white male suffrage. For information about which reforms were adopted and the factors contributing to their success, see, for instance, Keyssar, The Right to Vote, 26–52; Wilentz, The Rise of American Democracy, 197.

37. In creating this measure, we follow Ansolabehere et al., “Equal Votes, Equal Money.” Formally, this measure is: RRI_i = R_{j (i)}/N_{j (i)} / R_j/N_j, where j(i) indicates that county i is located in state j. R is the number of state representatives, and N denotes the corresponding voting population.

38. Specifically, the p-value of the difference in means and variance, respectively, of RRI between regions is less than 0.01.

39. Delaware is excluded because it had only three counties in each decade.

41. According to Wilentz (The Rise of American Democracy, 341), “Between 1820 and 1829 (alone), the population of the western part of the state rose by nearly 40 percent, compared to a rise of only about 2 percent in the Tidewater counties.”

Shepherd: 1830], 65–79Google Scholar; hereinafter denoted as PDV). In another speech at the convention, Madison (PDV, 538) expressed a similar justification for support for maintaining the unequal system of representation: “It is apprehended, if the power of the Commonwealth shall be in the hands of the Majority who have no interest in this species of property (slaves), that, from the facility with which it may be oppressed by excessive taxation, injustice may be done to its owners.”

45. This roll call is located in PDV, 654.

47. For instance, a delegate from present-day West Virginia proposed an amendment that “Resolved, that when the amended Constitution shall be submitted to the people, the following question, by way of amendment, shall be propounded to the people, for a final settlement of the principle of the apportionment of representation, viz: Shall the basis of Representation in both branches of the Legislature be white population exclusively?” (PDV, 575). While this motion was rejected, the roll call was not recorded.

49. One prominent contemporary politician said, “the increased value of the lands in certain sections has rendered this restriction on the taxing power so grossly absurd … that a hundred acres of land, worth fifty cents an acre, should pay one dollar (in) taxes, and that another hundred acres, worth fifty dollars the acre, should pay the same amount of tax”; as cited in Hamer, Philip, Tennessee: A History, 1673–1932, vol. 4 (American Historical Society: 1933), 318Google Scholar.

One historian claimed, “Clearly the major reason for a convention in the mid-1830s was the increasing uproar over the taxation of property”: Bergeron, Paul, Antebellum Politics in Tennessee (Lexington: University Press of Kentucky, 2015), 39Google Scholar. Furthermore, the 1796 constitution stipulated that amendments could only occur in a convention.

54. The significance of the estimates for TN prior to the convention (as shown in Table 1), and complete insignificance thereafter, suggests that the reforms to apportionment were meaningful.

56. Hamer claims that the electorate's strong demand for democratizing reforms meant that many prominent state politicians were either defeated in the elections for delegates or refused to run (e.g., future U.S. President, James K. Polk). The sitting governor even asked the sitting U.S. president, Andrew Jackson, to serve as a delegate, hoping he could stem the demands for reform. In his letter to Jackson, he began, “From the returns … we shall have a convention. This I regret, for I incline to the belief that the opinions of the people at this time are not favorable to the formation of a sound constitution.” Hamer, Tennessee, 319.

66. When one delegate said that all states had apportionment based on white population, another delegate responded, “as a political axiom, it (is) true that representation should be based upon free white population. It may be stated as truth, in that part of the Union north of Mason's and Dixon's line … Having slaves among us, all these political truths must be accommodated to the interests of the country.… The maxim that representation should be based upon population is not so entirely untrue, but it is altogether unsuitable to our circumstances.” The History and Debates of the Convention of the People of Alabama.

69. Indeed, from the outset, most Northern states largely implemented systems of representation that were based on total population or qualified voters and periodic reapportionment: Ansolabehere, Stephen and Snyder, James, The End of Inequality: One Person, One Vote and the Transformation of American Politics (New York: W. W. Norton, 2008), 42–45Google Scholar; Beramendi, Pablo and Jensen, Jeffrey, “Economic Geography, Political Inequality, and Public Goods in the Original 13 US States,” Comparative Political Studies 52, no. 13-14 (2019): 2235–82CrossRefGoogle Scholar. The latter authors argue that unlike Southern elites, who could largely meet their labor needs with slaves, the scarcely populated, larger Northern states’ need to induce migration into led them to commit in their initial constitutions to a population basis of apportionment.

The man of property should feel secure in his pursuits”; as cited in the Journal of the Convention Assembled to Frame a Constitution for the State of Rhode Island, at Newport, 1842 (Providence: State Printers, 1859), 33Google Scholar.

96. For Georgia, whose secession was likely pivotal to the ability to form the early Confederacy, a vote on whether to require voter ratification was held and rejected but not recorded.

In the states for which there are existing returns in the elections for convention delegates, secessionist candidates received approximately 50 percent of the total votes cast in Georgia, 52 percent in Louisiana, and 56 percent in Alabama.
