Louisiana Purchase (1803)

It sounds crazy today, but the Louisiana Purchase almost doubled the size of the United States overnight. Thomas Jefferson, at the time, the third to occupy the position of President of the United States, bought the massive 828,000 sq mi territory from France for $15 million, securing vital land and resources.

The purchase, however, didn’t mean that the United States also gained control of the totality of the territory, as it was inhabited by Native Americans. But in any case, the acquisition paved the way for westward expansion, providing a vast area for exploration and settlement, while enhancing America's geopolitical influence.

Commissioned by Jefferson, Meriwether Lewis and William Clark then embarked on a mission to map the newly acquired lands and find a viable route to the Pacific. Their legendary journey revealed the rich diversity of the western territories and established crucial relationships with Native American tribes.

Sacagawea, a Shoshone woman, played a crucial role as an interpreter and guide, helping the expedition navigate difficult terrain and gain trust with native tribes, significantly contributing to the mission's success. Ultimately, their detailed reports opened the frontier to future explorers and settlers.

The Oregon Trail (1811-1869)

Originally laid around 1811 by fur trappers and traders, the Oregon Trail soon became a critical route for thousands of emigrants moving west. Spanning over 2,000 miles from Missouri to Oregon, it was a perilous journey marked by harsh landscapes and, more often than not, disease.

Despite the hardships, the trail was improved to become passable by wagons, and it facilitated the mass migration of over 400,000 settlers during its peak, significantly contributing to the population growth and development of the Western United States.

California Gold Rush (1848-1855)

The discovery of gold at Sutter's Mill in 1848 triggered a massive influx of fortune seekers to California. The Gold Rush not only boosted the economy but also accelerated California's admission claim as the 31st state in 1850.

While prospectors initially used simple techniques like panning, the increasing complexity of gold extraction eventually required significant financing, favoring mining companies. And though the gold rush generated wealth worth tens of billions in today's dollars, only a few became rich; most participants earned little more than they had started with.

Homestead Act (1862)

Signed by President Abraham Lincoln, the Homestead Act offered 160 acres of public land to settlers willing to farm it for five years. The policy primarily encouraged individual farmers who were looking to operate their own farms, as opposed to slave owners who sought to buy large tracts of land and use slave labor.

The legislation encouraged widespread migration to the Great Plains, accelerating agricultural development and expanding American settlements across the West.

Building of the Transcontinental Railroad (1863-1869)

The completion of the first Transcontinental Railroad in 1869 revolutionized transportation in the United States. Connecting the East and West coasts, it facilitated trade, travel, and communication.

The extensive railroad network was built by three private companies on public lands, financed with federal bonds and various subsidies. Instrumental in the nation's economic growth, the Transcontinental Railroad also helped forge a sense of national unity and identity in the American consciousness.

The Great Sioux War (1876-1877)

Also known as the Black Hills War, the Great Sioux War was a series of conflicts between the United States and the Sioux tribes. The war was sparked by the encroachment of settlers and gold prospectors on Native lands, a conflict that had been escalating since the early 19th century.

Despite many Native American victories, such as the Battle of Little Bighorn - better known as Custer's Last Stand -, the war ultimately ended in the tribes' displacement. The conflict officially finished with the Agreement of 1877, in which the Sioux tribes were forced to cede property rights of their lands to the federal government, while clearly demarcated Indian reservations were established.

Oklahoma Land Rush (1889)

On April 22, 1889 - soon after the signing into law of the Indian Appropriations Act, which freed over two million acres of land for settlement - thousands of settlers raced to claim land in the Oklahoma Territory during the first of several land rushes.

Those who followed the rules and waited for the official start of the land rush were known as "boomers," while "sooners" sneaked into the territory before the designated time, risking penalties but gaining advantageous claims. This sparked hundreds of legal contests that had to be settled at local land offices or even by the U.S. Department of the Interior.

The Dawes Act (1887)

The Dawes Act aimed to assimilate Native Americans by dividing tribal lands into individual allotments. While intended to promote agriculture and integration, it resulted in the loss of tribal lands and culture.

The act was a controversial effort to reshape Native American society in the image of European-American settlers. It wasn’t until the Indian Reorganization Act, passed during the Franklin D. Roosevelt administration, that Native Americans regained some of their rights to own land collectively and form self-government.

Closing of the Frontier (1890)

In 1890, the U.S. Census Bureau declared the frontier closed, as there was no longer a discernible frontier line. This marked the end of a significant era of American expansion.

The closing of the frontier signified the nation's transition from a period of exploration and settlement to one of modernization and industrialization.

San Francisco, California

Image: Belle Co

San Francisco was never officially a state capital, but there was a 9-month period during the early governance of California when the capitol stood in the city’s Merchant’s Exchange building .

The seat of California’s capital moved multiple times among cities, including Monterey, San Jose, Vallejo, and Benicia. In the mid-19th century, it settled in Sacramento, strategically situated at the confluence of major rivers –which also meant proneness to flood . Severe flooding hit the city in the 1860s, temporarily incapacitating it as a state capital.

The administration then moved to San Francisco, which had been instrumental during the Gold Rush and remained a cultural and economic powerhouse. When Sacramento had recovered, though, the legislature moved back and it has remained the state capital since.

Savannah, Georgia

Image: Jessica Furtney

Savannah, the beautiful city in Georgia famous for its cobblestone streets and picturesque squares, was the state’s first colonial capital. It continued to hold the capitol following the American Revolution.

In the late 1700s, however, the capital moved inland to Augusta, where the population was growing. The decision was also meant to protect the government from potential coastal attacks .

Several cities served as capitals in the decades that followed, such as Louisville and Milledgeville. It wasn’t until a constitutional convention was held in Atlanta that the city’s potential as a state capital was recognized, and later realized.

St. Augustine, Florida

Image: Maddie DiFilippo

Known for its well-preserved colonial architecture, like the Castillo de San Marcos fortress , St. Augustine was the capital of East Florida for hundreds of years, since Spanish rule.

When Florida became a U.S. territory, St. Augustine, on Florida's northeast coast, maintained its role as one of two capitals, alongside Pensacola, which served West Florida. However, the difficulty of travel between these two cities led to inefficiencies in governance.

A halfway point was set exactly at Tallahassee to make access easier for legislators of both sides. To this day, St. Augustine maintains many constructions and a strong heritage from its colonial past.

4

New Orleans, Louisiana

Image: Stella He

When Louisiana was admitted into the Union, vibrant New Orleans was the state capital, and it remained so for over 30 years until the government seat was changed to Baton Rouge.

New Orleans was the largest and most economically significant city in the state at the time, so it was a natural choice. Still, its location also posed challenges, like disease outbreaks that often plagued it, and the powerful political influence of the French Creole population .

Eventually, Baton Rouge became the official capital, and its new Gothic Revival-style capitol building opened in the mid-19th century. Today, New Orleans remains a cultural hub for the state and the country.

5

Lewiston, Idaho

Image: Anthony Camerlo

The original capital of Idaho was upstate Lewiston, a key shipping hub thanks to its access to river transport. But the discovery of gold in the Boise Basin meant that the population –and the riches– flew to southern Idaho.

With the majority of settlers now in the south, the capital's relocation was pushed. Lewiston residents did not take this lightly: They fiercely resisted losing the capital and went so far as to lock the territorial seal and papers in the town jail to prevent their removal.

Federal troops had to intervene to complete the relocation. Today, Lewiston still proudly proclaims itself as "Idaho's First Territorial Capital," a line displayed everywhere downtown.

6

Plymouth, Massachusetts

Image: donwhite84

Plymouth, located in southeastern Massachusetts on Plymouth Bay, was the landing site of the Pilgrims in 1620. For many decades it remained its capital until the colony merged with that in Massachusetts Bay.

After the merger, Boston, a city with a larger population and a central hub for trade and governance, was designated the new capital. But Plymouth is still considered "America's Hometown" and hosts elaborate Thanksgiving celebrations annually.

Plymouth will always retain its historical significance, such as being the home of Plymouth Rock , which commemorates the site of the disembarkation of the Mayflower Pilgrims.

Kingston, New York

Kingston is located along the Hudson River in Ulster County, New York, with a scenic backdrop of the Catskill and Shawangunk Mountains.

It retains its Revolutionary War-era stone buildings, historic landmarks, and its title as the "birthplace" of New York State's government; It was its first capital. But when it became a center for revolutionary activities in the late 18th century, British forces burned the city in retaliation.

Kingston was rebuilt, but it never regained its capital status. Albany was later chosen as the capital for its central location and strong infrastructure.

8

Detroit, Michigan

Image: Alex Brisbey

Detroit, a.k.a. "Motor City," is not just the center of the U.S. automotive industry, but was Michigan's first capital before it moved inland to Lansing.

Michigan Territory had Detroit as its center, and it remained so even after it became a state. But there were concerns over Detroit's proximity to the Canadian border , and, as with many other capitals, a desire to fix the capitol in the state’s center.

Lansing, just a small settlement at the time, was more accessible and more secure. Detroit didn’t stay behind, though; Its role as a transportation hub during the Industrial Revolution helped it become a manufacturing powerhouse .

Kaskaskia, Illinois

Image: Dave Hoefler

Kaskaskia is now nearly a ghost town , a quiet community of fewer than 20 residents. This is due to Mississippi River flooding and shifting channels –but it was once its state capital.

Situated in Randolph County, Illinois, near the Mississippi River, it’s uniquely located on the western bank of the river. In the early 19th century it was a center for trade and governance and remained the capital until the legislature decided to relocate to Vandalia.

Vandalia, inland and growing, was a reasonable choice back then, but it would be replaced by Springfield eventually, largely due to the efforts of Abraham Lincoln .

10

New Castle, Delaware

Image: jakob

New Castle served as Delaware’s colonial capital during the 17th and 18th centuries. It was here, in 1776, that Delaware declared independence from both Pennsylvania and Great Britain, establishing itself as a state.

The city’s location by the Delaware River was key during colonial times, but it also made it susceptible to British naval attacks during the American Revolution. That was why the seat was moved to Dover, although it wasn’t made the permanent capital until the 1780s.

New Castle still keeps its well-preserved colonial architecture, particularly in the district surrounding its courthouse.

The doctor said so

Image: Vinicius Amano

It's not news that alcohol was completely banned across the country from 1920 to 1933. But, you know, every law has its loophole. It's said that during Prohibition, some doctors took advantage of their authority to prescribe a peculiar medicine: whiskey! Well, if the doctor prescribed it, what could the cops possibly argue?

2

The queen

Image: Daniel Vogel

Women also played an important role during Prohibition on both sides of the law! One of the most notorious was Cleo Lythgoe, a.k.a. the "Queen of the Bootleggers." As her nickname suggests, she was one of the most successful bootleggers of those years. That's right! She built an empire, running a major underground operation that supplied alcohol to secret bars.

Clever marketing

Image: April Klein

Although they feel like something recent, marketing strategies have been around for a long time. In fact, even during Prohibition, clever sales tactics flourished by exploiting the nation's circumstances. This was the case with the so‑called "grape bricks," blocks of concentrated grape juice that came with some rather peculiar warnings, such as "NOT to dissolve in water, add yeast and store in a cool place for 21 days, or it may ferment and turn into wine."

NASCAR

Image: Simon Hurry

Although it may seem like nonsense, NASCAR's origins are closely related to bootlegging during the Prohibition era. The "moonshiners" were those who transported illegal alcohol. These drivers were skilled, relying on speed and sharp maneuvers to outrun the law. Those same driving techniques later helped give rise to stock car racing.

5

Sacramental

Image: Rey Proenza

Prohibition was full of loopholes. But undoubtedly, one of the most obvious ones was the allowance for sacramental wine. Since wine used in church masses was permitted, it led to more people attending certain services, and even the rise of some pseudo-religions!

6

A payment issue

Image: Mackenzie Marco

Prohibition agents were in charge of enforcing the dry law. However, there was one big problem the authorities overlooked: these agents were poorly paid. That small detail helped the illegal liquor trade thrive. Since agents weren't well paid, bootleggers found them easy to bribe.

7

Risky times

Image: Nick Fewings

The fight against alcohol sales was far from easy, and historical records suggest that, as a result, the authorities took some drastic measures. One of them was the decision to add highly toxic chemicals to the alcoholic beverages circulating at the time! But here's the most surprising part: many people knew -or at least suspected- and still drank their gin and tonic anyway!

8

A lot

Image: Sérgio Alves Santos

We know that Prohibition gave rise to the famous speakeasies, and we know there were a lot of them, but how many? Well, because they operated in secret, it's hard to know exactly how many speakeasies existed across the country. Still, one fact gives us a clear picture of that time: Speakeasies actually outnumbered the bars that existed before Prohibition.

The man in the green hat

Bootleggers were everywhere, even where you'd least expect them. During the Prohibition years, there was one man who operated as the main bootlegger of Congress. He was nicknamed "The man in the green hat" as a reference to his trademark green fedora.

After sunset

Image: Anna Asryan

In Detroit, the Police Department grew tired of constantly chasing smugglers down the Detroit River. As these chases were extremely risky and often ended in accidents, the Detroit Police Department adopted an unofficial policy: "No active chases after sunset." As you can imagine, this gave smugglers a lapse of time each night to move without worry.
