How the States Got Their Shapes: A full breakdown to the Award‑Winning Documentary Series
The How the States Got Their Shapes television documentary series, originally aired on the National Geographic Channel, has become a cornerstone for anyone curious about the geographic and historical reasons behind the borders of the 50 U.states. S. Because of that, this multi‑season production blends striking visual storytelling with expert interviews, scientific analysis, and on‑location investigations to explain why each state looks the way it does today. Whether you’re a geography teacher, a curious traveler, or a student preparing for a social studies project, this guide dives deep into the series’ content, production approach, and lasting impact, while also highlighting the key themes and scientific principles that make the show both educational and entertaining Turns out it matters..
Introduction: Why the Shapes Matter
The United States is one of the few nations whose internal borders are easily recognizable on a map, each state possessing a unique outline shaped by centuries of political negotiation, natural geography, and even quirky historical accidents. How the States Got Their Shapes tackles the question that has puzzled many: why do the states have the borders they do? The series explains that these boundaries are not arbitrary; they reflect Native American territories, colonial claims, transportation routes, economic interests, and even the whims of early lawmakers. By exploring each state’s formation, the documentary reveals how geography, politics, and culture intertwine to create the mosaic of shapes we see on today’s maps.

Overview of the Series
Production Background
- Network and Premiere: The series premiered on National Geographic in 2010 and ran for three seasons, totaling 45 episodes.
- Creators: Produced by Sean M. Flynn and directed by a team of experienced documentary filmmakers, the show combined high‑budget visual effects with on‑site filming.
- Approach: Each episode focuses on a specific region or a handful of states, employing a mix of archival footage, computer graphics, and interviews with historians, geographers, and anthropologists.
Episode Structure
The series is organized into thematic blocks:
- “The Foundations” – Covers the early colonial period and Native American influence.
- “The Frontier” – Explores westward expansion and the impact of the Louisiana Purchase.
- “The Industrial Age” – Examines how railroads and trade routes reshaped state lines.
- “Modern America” – Discusses the political and demographic forces shaping contemporary borders.
Each episode uses a consistent format: an opening narrative, scientific explanation, and a concluding “Why It Matters” segment that ties the historical event to present‑day implications.
Key Themes Explored
1. Colonial Claims and Native American Territories
The earliest state shapes were dictated by European powers. That said, spain, France, and Britain each claimed vast tracts of land, and the resulting borders often followed rivers, mountain ranges, and coastlines. The documentary highlights how Treaty of Paris (1763) and Treaty of Paris (1783) redrew the map, granting the United States its Atlantic seaboard states—Georgia, South Carolina, North Carolina, Virginia, Maryland, Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, and Massachusetts—while leaving the interior to be negotiated later.
Native American nations played a crucial role as well. Many tribal territories acted as buffer zones between colonial settlements, and later, treaties often recognized these areas, influencing the placement of future state lines. The series uses animated maps to illustrate how tribal lands were gradually encroached upon, leading to the eventual incorporation of states like Ohio, Indiana, and Illinois And that's really what it comes down to. No workaround needed..
2. The Northwest Ordinance and the “Straight‑Line” Principle
Among the most recognizable patterns in the series is the grid-like layout of the Northwest Territory. Because of that, after the Revolutionary War, the United States adopted the Northwest Ordinance of 1787, which established a systematic approach to surveying land. This ordinance introduced the section‑township system, dividing land into 6‑mile squares (townships) and 1‑mile squares (sections). The documentary explains how this methodical surveying created the straight‑line borders seen in states such as Ohio, Indiana, Illinois, Michigan, and Wisconsin But it adds up..
The series also notes that this grid system was not without controversy. Indigenous peoples were often displaced without consent, and the “straight‑line” principle sometimes ignored natural features like rivers and mountains, leading to later disputes over water rights and resource allocation.
3. The Role of Transportation and Trade
Transportation networks have been a driving force behind state boundary decisions. Day to day, the Erie Canal, for example, not only spurred economic growth in New York but also solidified the state’s northern and southern boundaries. The documentary illustrates how railroads in the 19th century prompted the creation of new states like Kansas and Nebraska, as rail companies lobbied for routes that would minimize travel time and maximize profit.
On top of that, the series highlights the “border states”—Kentucky, Missouri, Maryland, Delaware, and West Virginia—that were strategically important during the Civil War. Their locations were influenced by the desire to control key river systems and trade routes, underscoring how transportation infrastructure can literally draw lines on a map The details matter here..
4. Political Compromise and the “Equal Footing” Doctrine
Political negotiations have often resulted in bizarre state shapes. The “Equal Footing” doctrine—the principle that new states enter the Union on an equal footing with existing ones—led to the creation of states with irregular borders to balance representation. A notable example is Colorado, whose jagged western edge was designed to include the lucrative silver mining region of the Rocky Mountains, ensuring economic equity among settlers.
The series also discusses the “Missouri Compromise” and “Compromise of 1850”, which used geographic lines (the 36°30′ parallel for Missouri) to manage the slavery debate, directly influencing state boundaries and, consequently, the shapes we see today.
Scientific Explanation: How Cartography Shapes Perception
Geographic Information Systems (GIS) in the Series
How the States Got Their Shapes leverages modern GIS technology to reconstruct historical maps and overlay them with contemporary boundaries. This allows viewers to see how topographic features—mountains, rivers, and deserts—have been incorporated into state lines. The documentary explains that natural features often serve as “natural borders” because they are difficult to cross, making them logical choices for political boundaries.
The Mathematics of Surveying
The series digs into the mathematics behind the Public Land Survey System (PLSS). Using simple geometry, surveyors divided land into a grid of townships and sections. Still, the documentary demonstrates how this system created uniform 6‑mile by 6‑mile squares, which, when combined, produce the rectangular shapes characteristic of the Midwest. The visual effect is striking: the flat, agrarian landscape of states like Kansas and Nebraska appears as a patchwork quilt of straight lines That's the part that actually makes a difference..
Impact and Legacy
Educational Influence
Since its debut, How the States Got Their Shapes has been adopted by teachers across the United States as a supplementary resource for geography and history curricula. The series’ blend of visual storytelling and scholarly insight makes complex historical concepts accessible to middle‑school and high‑school students alike Simple, but easy to overlook..
