Common historical fallacies

Creating Common historical fallacies taught by high school & other teachers

• teachers are frequently responsible for erroneous historical facts or interpretations
  • teachers have a point of view that inescapably informs their teaching
• the best teachers "teach" not "preach"
  • but even the most objectively-minded teacher has as a point of view, an underlying outlook

US History fallacies

Slavery was the basis of the colonial and antebellum American economy

logical fallacy 1: slave-produced exports were the driving force of the antebellum U.S. economy

• while cotton represented a significant portion of antebellum exports,
• and while cotton was the dominant slave-produced southern agricultural product,
  • not all cotton was produced by slaves/ slave owners;
  • exports were not a significant portion of the overall U.S. antebellum economy

Enslaved populations in the Thirteen Colonies in 1770.[1]

Evolution of the enslaved population of the United States as a percentage of the population of each state, 1790–1860

logical fallacy 2: colonial period slave v. overall population growth

• we can measure the relative importance of slavery, as well as its expansion, by studying slave population numbers and growth
• growth of colonial African slavery was linear (upward but constant) until the development of the cotton gin
  • up to 1800, colonial population growth was significantly higher for whites than for slaves (see chart)
• CONCLUSION: therefore increases in the slave population was not the basis of the colonial development

• after 1800, the slave population increased dramatically following introduction of the cotton gin
• non-black population growth exceeded that of blacks (free and slave) for all decennial (every 10 years) census counts except 1810 & 1880

logical fallacy 3: colonial per capita wealth not reliant upon slavery

• in 1774, slavery represented a significant proportion of per capita private wealth:
  • 28.7% of national per capita wealth
  • 31.7% of southern per capita wealth
    • measured here as an asset, slavery was less than 1/3rd overall colonial wealth
    • = static measurement (snapshot of current values)
    • but not a measurement of economic output
      • just as an office building has a value but its economic output is measured not by its value but by the sum of its rents

logical fallacy 4: black population growth for about slavery

• according to the decennial Census count:
  • only in the 1810 Census count did black population growth under slavery exceed that of non-black population growth
    • this growth coincided with the introduction of the cotton gin and rapid expansion of slavery across the deep South
• notably, black population growth has exceeded non-blacks following emancipation and desegregation
  • equally notable,
• Conclusions:
  • while slave and free black population grew significantly under slavery, emancipation and desegregation led to higher relative population growth for blacks
  • segregation inhibited black population growth, thus racial discrimination is not conducive of population growth (and we can infer from that economic activity)

  • the data also show that lower population growth for blacks occurred following segregation

Colonial and early Republic southern white slave owners & manumission

Fallacy no. 1: white slave owners did not think the institution was wrong

• while there was extensive racism and expansion of slavery, southern whites were not unaware of the evils of the institution
• slave-owner Thomas Jefferson famously emancipated his slaves only after his death
  • (which was a common practice)
  • however, Jefferson recognized that slavery was wrong
    • and that the "wrath" of God would punish those who violated the "liberties of the nation", which he believed should include those of slaves to be freed ("total emancipation")

click EXPAND to read passage by Jefferson on liberty, slavery and emancipation from the Notes on the State of Virginia, 1790:

And can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are of the gift of God  That they are not to be violated but with his wrath?  Indeed I tremble for my country when I reflect that God is just; that his justice cannot sleep for ever; that considering numbers, nature and natural means only, a revolution of the wheel of fortune, an exchange of situation, is among possible events; that it may be come probable by supernatural interference!  The Almighty has no attribute which can take side with us in such a contest.  But it is impossible to be temperate and to pursue this subject through the various considerations of policy, of morals, of history natural and civil.  We must be contented to hope they will force their way into every one=s mind.  I think a change already perceptible, since the origin of the present revolution.  The spirit of the master is abating, that of the slave rising from the dust, his condition mollifying, the way I hope preparing, under the auspices of heaven, for a total emancipation, and that this is disposed, in the order of events, to be with the consent of the masters, rather than by their extirpation.
- Thomas Jefferson, Notes on the State of Virginia, Query XVIII

Fallacy no. 2: white slave owners did not free their slaves

• slave owners did free slaves and sometimes all of their slaves, as did Virginia plantation owner Robert Carter III

click EXPAND to read the Wikipedia entry on Robert Carter III's manumission (freeing) of his slaves:

Manumission<br>
In the years after the Revolutionary War, Virginia's legislature (having barred the slave trade in 1778) passed several laws sympathetic to freeing slaves, although it did not pass a law legalizing manumission until 1782, and throttled many petitions for wider emancipation. Numerous slaveholders in the Chesapeake Bay area freed their slaves, often in their wills (like Quaker John Pleasants) or deeds, and noted principles of equality and Revolutionary ideals as reason for their decisions. The number of free African Americans increased in the Upper South from less than one percent before the Revolution, to 10 percent by 1810. In Delaware, three-fourths of the slaves had been freed by 1810. In the decade after the act's passage, Virginians had freed 10,000 slaves, without visible social disruptions. The price of slaves reached a 20-year low as the percentage listed as "black, tithable" (i.e. slaves) fell below 40%, the lowest point in the century. However, Virginia's courts sidestepped issuing appellate decisions ratifying emancipation until 1799, and the methodology of within-life emancipation was not established.
