The Myth of America's Westward Expansion
ROBERT E. MAY
Lately, considerable controversy has swirled over how U.S. history education
marginalizes the story of Hispanics/Latinos in the geographical space that became the
United States of America, a deficiency inadequately redressed by annual observances
(since 1989) of National Hispanic Heritage Month between September 15 and October
15.
According to many authorities, U.S. social studies and history students encounter what
M. Elizabeth Boone dubs an “English-only definition of U.S. national identity.” Boone
observes that between 1876 and 1915 the United States constructed its history by
originating the nation at Plymouth Rock rather than in places with Spanish exploration
and colonization histories—e.g., Florida and New Mexico–setting the nation on the path
reflected in modern education. This in a country whose Hispanic/Latino population
surpasses 18 percent and that has more speakers of Spanish than Spain, and where
more than one in four public school students is of Hispanic/Latino background.[1] When
author Carrie Gibson subtitled her recent book El Norte about persons of
Hispanic/Latino descent in North America as an “Epic and Forgotten Story,” she chose
her second adjective advisedly.[2]
Recently, Texas Twentieth District Congressman Joaquin Castro complained to an
interviewer, “we have been left out of much of the telling of American history and our
state histories, including in my home state of Texas.” Not only do such omissions
damage the self-esteem of Hispanics/Latinos, they also, Castro argued, make them
historically invisible to the nation’s population writ large, since Americans typically fail
to “associate us with any particular time period” in their country’s past. Castro quipped
that the only Latino or Mexican American persons he encountered during his social
studies education in San Antonio were confined to defending the Alamo during the
Texas Revolution.[3]
Although causatively linking such erasures to chronically high national dropout rates for
Hispanic/Latino students from U.S. public schools is problematic given the multiple
factors contributing to dropout decision-making,[4] they likely are a contributing factor.
U.S. social studies coursework highlighting mythologies of American prosperity,
innocence and exceptionalism strikes many Hispanic/Latino students as irrelevant to
their own worldviews, self-identities, and prior life experiences (especially including high
poverty rates in Hispanic/Latino communities).[5] To be sure, content omissions and
distortions are being contested at state, regional, and national levels.[6] But remedial
initiatives as are now underway in Connecticut are offset by countervailing pressures,
especially as blowback against the teaching of critical race theory subverts the logic of
Hispanic/Latino studies.[7]
What explains this marginalization? Should we casually chalk it up to the racism,
ethnocentrism, and subconscious prejudices of Anglo historians, schoolteachers, and
textbook publishers? Or is something else also at work?
As a historian whose books have centered on the efforts of white southerners to expand
their slave labor system (the so-called “peculiar institution”) southward into Latin
America before the Civil War, I suspect that conventional assumptions that America
expanded westward degrade Hispanos/Latinos in U.S. social studies/history education
in subtle but profound ways by predetermining the very framing of the nation’s historical
narrative.
Let me suggest that by simply reimagining the very geography and maps of U.S.
nineteenth-century territorial expansion we might make history education more relevant
to Hispanic secondary and even collegiate students. I do not offer this corrective naively
as a cure-all for disconnects between Hispanic/Latino students and U.S. history. But I
do think it provides one way to jump-start the remedial process.
The problem derives at least in part from a 129-year-old theory. On July 12, 1893, the
University of Wisconsin history professor Frederick Jackson Turner, at the World’s
Columbian Exposition in Chicago, gave arguably the most influential speech by an
American historian in U.S. history. Turner wrote the address, entitled “The Significance
of the Frontier in American History,” as a reaction to a recent announcement by the
superintendent of the U.S. 1890 census that the country was now so settled it no longer
had a clear frontier line.
In his speech, Turner attributed his nation’s evolution and culture to its waves of
movement westward and the norms fostered by its frontier process during each wave.
As he put it in one of his first sentences, “The existence of an area of free land, its
continuous recession, and the advance of American settlement westward, explain
American development.” In what followed, Turner elaborated his “frontier thesis,”
explaining that the experiences of living primitively on successive frontiers encouraged
the emergence of America’s distinctively national traits—particularly egalitarianism,
representative democracy, inventiveness, and nationalism.[8]
Over the following century, academic historians refuted particular arguments within
Turner’s frontier thesis. For instance, they contended that it can just as easily be argued
that American democratic institutions arose first in heavily populated eastern areas as
on the frontier.[9]
But historians rarely challenged Turner’s core insinuation that U.S. territorial expansion
occurred in an exclusively westward direction. Turner’s biographer Ray Allen Billington
helped ensure this longevity with his lengthy 1949 tome Westward Expansion: A History
of the American Frontier, a standard textbook mildly corrective of Turner’s theories that
was assigned in many collegiate western history courses and went through six editions.
On his book’s third page, Billington called on readers to picture “the Anglo-American
frontier as a migrating geographical area which moved westward from Atlantic to
Pacific over the course of three centuries.”[10]
This entwining of western migration and American expansion is so embedded in the
nation’s historical narrative that historians reaffirm the trope reflexively. Books about
U.S. history abound in pronouncements and asides that American expansion pointed
westward. In his Pulitzer Prize winning study What Hath God Wrought: The
Transformation of America, 1815-1848, Daniel Walker Howe notes that “westward
expansion rendered inescapable the issue [slavery] that would tear the country asunder
a dozen years later.” In Sex and Manifest Destiny: The Urge That Drove Americans
Westward, Martin Naparsteck asserts an intention to illuminate how “the natural human
sex drive contributed to the drive to expand the United States westward across the
entire continent.” A historian of America’s secession crisis observes how “slavery’s
expansion into the West was the chief point of contention between North and South in
the 1850s.” A student of American foreign policy suggests it is high time that scholars
place the history of “U.S. westward expansion” within the context of European
colonialism.[11]
Similarly Turnerian have been the many books for young readers titled Westward
Expansion, aimed at students in elementary and secondary education.
No wonder that with historians preaching America moved relentlessly westward, the
association repeats ad nauseum in incalculable numbers of forums. St. Louis’s
Museum at the Gateway Arch promotes itself as an institution covering “201 years of
history about the westward expansion of the United States.”[12] C-SPAN online
programs offer titles such as “American Westward Expansion” and “Civil War and 19th
Century Westward Expansion.”
The thing is, America’s pre-Civil War territorial expansion was not nearly as uni-
directional as the stereotype maintains. Though there are no C-SPAN videos titled
“American Southward Expansion,” much of U.S. territorial expansion before the Civil War
occurred southerly as well as westerly, as people realized at the time. During one
congressional debate two years before the Civil War, Senator John Hale of New
Hampshire, a onetime minor party presidential candidate, griped, revealingly, that
America’s expansion “always travelled South” (rather than northward or westward)![13]
Despite American leaders’ ambitions during the War of 1812 and at other times in the
nineteenth century to annex the Canadian provinces, then British colonial possessions,
to the U.S. domain, those dreams were never realized (though Anglo-American boundary
adjustments in the 1840s could be interpreted as adding small slices of Canada).[14] In
contrast, the U.S. made huge gains to the south before the American Civil War at the
expense of France, Spain, and Mexico by the Louisiana Purchase from France (1803),
the Transcontinental (or Adams-Onís) Treaty with Spain (1819) acquiring Florida, the
annexation of Texas (1845), the Mexican Cession ending the U.S.-Mexican War of 1846-
1848, and the Gadsden Purchase from Mexico (signed in 1853 and ratified in 1854). The
latter gained nearly 30,000 square miles of Mexico that eventually was incorporated into
the southern reaches of today’s states of New Mexico and Arizona.
To be sure, these acquisitions grew America westward. This holds even for Florida. Its
“panhandle” lies west of coastal states like South Carolina and Georgia. Further, the
Adams-Onís Florida treaty defined a U.S.-Spanish boundary in the southwest along the
42nd parallel extending to the Pacific Ocean, eliminating a potential Spanish
impediment to future U.S. designs on the Pacific Northwest. Today’s southern and
onetime slave state of Louisiana was only a fraction of the territory France gave up in
1803 for $15 million in 1803, as the Louisiana Purchase cession included some 828,000
square miles from the Mississippi River to the Rocky Mountains.[15]
Yet, too often overlooked is that all these acquisitions pointed southward as much as
westward, as even a most superficial glance at a map of the continental U.S. shows.
Louisiana might have been west of Georgia and Florida, but it was south of Wisconsin
and Minnesota and southwest of states like Massachusetts, Pennsylvania, and New
York. More to the point, slavery was legal in the entire Louisiana Purchase territory when
Thomas Jefferson’s administration negotiated its acquisition from France, and its lower
and most heavily populated extremes, including the current state of Louisiana, had an
established staple crop economy and a population about 50% enslaved.[16]
For all of his well-known, stated reservations about the evil effects human bondage had
alike on slaveholders and the enslaved, Jefferson initiated no steps to eradicate the
institution in his new acquisition either before or following the treaty’s drafting or
ratification.[17] Indeed, Article 3 of the purchase treaty ensured that current residents
would hold the same “rights, advantages and immunities” of U.S. citizens after
annexation including their “property” (emphasis mine), granting Louisiana’s pre-
annexation slaveholders legitimate title to their slave property equivalent to that already
held by U.S. slaveholders.[18]
We must not forget that the U.S. southern slave states of Louisiana, Missouri, and
Arkansas never would have come into being had it not been for the Louisiana Purchase,
and it is likely the U.S. never would have gained the slave state of Texas had it not first
acquired adjacent Louisiana to its east. An immediate boom in Louisiana slave-
produced sugar followed the U.S. takeover. And yet, somehow, we tend to remember
the Louisiana Purchase as part of America’s unceasing march westward rather than
westward and southward.
And what about Texas, also south or southwest of much of the remainder of the United
States at the time? As Annette Gordon-Reed (on the basis of her own experiences
attending Texas schools) reminds us in On Juneteenth, the state’s nineteenth and
twentieth century history is commonly stereotyped as a western tale of cowboys,
ranchers, and oilmen. This is horribly misleading, eliding Texas as a southern chapter of
U.S. territorial growth. It obscures the “extremely humid subtropical climate” of eastern
Texas, where cotton culture and slave labor flourished in the wake of American
infiltration in the 1830s and annexation in 1845. Gordon-Reed pointedly notes that the
legendary William Barret Travis, who commanded the revolutionary forces at the Alamo
in 1836, brought an enslaved servant there. So did his famed fellow revolutionary Jim
Bowie, who previously had been involved in slave-trading and brought his enslaved cook
Betty with him to the besieged onetime mission.[19]
Had Texas lacked potential for slave-produced cotton, few settlers from slave states
would have migrated there in the 1830s, and it is possible the United States never would
have annexed it in 1845. Without an economy revolving around slave-produced cotton
at the time of Lincoln’s election, it is unlikely Texans would have voted in 1861 to
secede and join the Confederacy. Arguably, Texas remains today more a southern state
than a western one. But it was certainly so in the mid-nineteenth century.
As Rachel St. John–an expert on the geography of U.S. expansion–notes, we would be
better served conceptualizing Texan annexation within “a distinctly southern and pro-
slavery view of American destiny” than as part of America’s rush to the Pacific.[20] At
the very least, the story of Texas annexation and statehood is as much a tale of
America’s southward expansion as evidence of its westward thrust.
And although the Mexican Cession and Gadsden Purchase allowed U.S. settlement and
development of the Southwest and California and facilitated American commercial and
eventual territorial penetration of the Pacific and Asia (e.g., Hawaii and the Philippines),
it is incomplete to state, as one historian does, that the acquisition of Mexican territory
in the 1830s and 1840s “ignited violent new battles over whether slavery would be
allowed to expand west.” These very acquisitions paved the way for potential U.S.
expansion projects in Latin America.[21]
It was in the 1850s that U.S. adventurers known as “filibusters” followed up on their
nation’s prior expansion by invading and trying to conquer Mexico and Central America
as well as Spain’s then colony in Cuba.[22] One filibuster, William Walker, conquered
most of Nicaragua and legalized slavery there, though it had been previously abolished
in Mexico and all of Central America.[23] During the 1850s, both U.S. presidents,
Franklin Pierce and James Buchanan, tried to buy Cuba from Spain. In 1854, America’s
most important diplomats in Europe convened in conference in Belgium and issued
their infamous “Ostend Manifesto” arguing that if Spain refused to sell Cuba to the U.S.,
that the U.S. would have justification to seize it and keep it.[24] And in the years
immediately before the Civil War, U.S. President James Buchanan seriously pursued the
project of gaining his country a protectorate over Mexico.
Few students in U.S. schools learn that a disagreement over whether U.S. slavery should
be allowed to expand into Latin America played a significant role in the famed rivalry
between Abraham Lincoln and Stephen Douglas. Nor are they informed that
disagreements over this same issue helped shatter all hopes following Abraham
Lincoln’s election in 1860 that the North and South might resolve their differences over
slavery with a compromise, warding off the civil war that followed. They might learn that
before the Civil War there were movements to “colonize” U.S. slaves and free Blacks in
Africa, but probably never get an inkling of the efforts to colonize U.S. Blacks in Latin
America, especially during the Civil War.[25]
I am suggesting here the need for educators, state departments of instruction, and
textbook companies to collaborate in designing a corrective history/social studies
curriculum that, shorn of Turnerian perspectives, reframes the American story
by highlighting that America became a continental empire by extending south as well as
west. Such a curriculum would have to do more than cover Spanish conquests and
settlement of Florida and the Southwest during America’s colonial period (a feature
common to many U.S. social studies and history textbooks at all educational levels), the
Texas Revolution, and the U.S.-Mexican War. Rather, this reframing would need to
be chronologically expansive, thoroughly infusing treatments of U.S. history from the
American Revolution onward.
Let me give just one example of how this kind of a revamped social studies curriculum
might better engage Hispanic/Latino students. When studying the filibuster invasion of
Mexico in 1855 by Texas Ranger officer James Hughes Callahan, an attack that burned
and plundered the border town of Piedras Negras, Mexico, I became aware that a key
incentive for the invasion was the desire of Callahan and his men to recover slaves who
had escaped bondage in Texas by fleeing across the Rio Grande.[26]
White southerners before the Civil War, in fact, were infuriated at Mexico for providing
haven to their enslaved people.[27] Students need to learn about this twist on our usual
narratives about the Underground Railroad. Nearly always, we picture British Canada as
the safe refuge for escaped enslaved Blacks hoping to get beyond the grasp of
Congress’s Fugitive Slave Act of 1850. Yet, several thousand slaves sought freedom in
Mexico.[28]
Highlighting the Mexican alternative for escaped slaves, in turn, invites classroom
investigations into Mexico’s antislavery history, the roots of cultural differences
between the U.S. and its neighbor to the south, and, for that matter, the history of
slavery and abolition in Central American states as well. Students might instinctively
wander from such material into the racial, ethnic, and gender constraints on the U.S.’s
heralded democratic traditions and history.[29]
This is the very kind of inquiry, incidentally, that Critical Race Theory in its best
applications invites. It is, after all, a testament to Mexico’s less rigid race conventions
that many escaped slaves sought Mexican citizenship after arriving there. Such
musings might be a seamless lead-in to classroom considerations of the significance of
the U.S. Supreme Court’s definitions of citizenship in the Dred Scott Decision of 1857, a
case that all high school graduates should understand.
In an assessment of the impact of the standards movement in U.S. social studies
education on Latino students, Kennesaw State University Assistant Professor of History
and History Education Caroline Conner recently suggested that although the Obama
administration’s Every Student Succeeds Act (2015) has arguably improved the
coverage of African American and Native American history within U.S. secondary
education, at least superficially, it has been less constructive when it comes to Latinx
and Asian American inclusion. Instead, those groups continue to be “drastically
underrepresented and misrepresented.”[30] Potentially, a re-directing of the common
wisdom about U.S. territorial expansion might help social studies/history recapture
forfeited Hispano/Latino audiences. We need to conquer our simplistic presumption
that America expanded westward. Otherwise, that very trope will continue to stifle the
thirst for history learning among U.S. minority populations.
