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.

Lewis and Clark Expedition (1804-1806)

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.

Oreo

Who better to start this article than Milk’s absolute best friend? Oreo has been the king of American cookies since its very beginning. Dunk it, twist it, or just eat it: There’s no bad way to eat an Oreo.

Did you know that Oreos were originally sold as part of a trio of cookies? Not only that, they were sold under a much less marketable name: Hydrox, which doesn’t really fit such a delicious treat.

Snickers

Have you ever wondered where the name "Snickers" comes from? You might be inclined to think that it comes from the hearty laughter that might arise after eating one of these delicious bars, but the answer is actually rather strange: It comes from a horse! Specifically, it was the name of the Mars family horse, who decided to immortalize their beloved stallion in 1930.

Regardless of its unusual name, Snickers is one of the most beloved candy bars in America, if not the world. Over their 90 years of history, they have produced a number of delicious variants of their traditional caramel and peanut filling, including dark and white chocolate, as well as peanut butter and almond.

Apple pie

We’ll continue with an American icon. If you ask anyone from outside the United States to choose 3 things to define our country, they’ll probably include apple pie . This beloved sweet treat is heavily associated with the 4th of July celebrations, but let’s be honest: There’s no bad time to have a slice or two of apple pie.

For such a culinary staple, apple pie definitely has a lot of variants. For instance, you can enjoy a delicious apple pie à la mode by adding a scoop of vanilla ice cream. Other toppings include custard, whipped cream, or (surprisingly) a slice of cheddar cheese.

Reese’s Peanut Butter Cup

We debated which Reese’s product to include in this list: their delicious Peanut Butter Cups or their outstanding Pieces. We decided to go for the Peanut Butter Cup, if only for one reason. This amazing product was one of the first to showcase what a dynamic duo of chocolate and peanut butter make.

The story of Reese’s Peanut Butter Cup s goes back to 1928, when H. B. Reese, a dairy farmer employed by the Hershey Company, decided to start his own candy company after he was let go of his job. The rest is history! Almost 100 years after, Reese’s Peanut Butter Cups are still one of America’s most cherished sweet treats.

Beignets

If you ever find yourself in the beautiful city of New Orleans, you’ll be amazed by everything "The Big Easy" has to offer, from its amazing jazz, gorgeous architecture, and mouth-watering food. In that regard, take this piece of advice to heart: Don’t leave New Orleans without having some delicious beignets with a hot cup of coffee.

Like many of the things that make New Orleans so special, beignets come directly from French culture. They were most likely brought over by French colonists in the 18th century. However, Louisiana-style beignets stand out because they are topped with powdered sugar and are mostly eaten for breakfast.

Boston Cream pie

Boston is known as "Beantown" for its affinity for beans, but don’t you dare think beans are the only culinary treat this city has to offer. With that in mind, we would like to present a slice of delicious Boston cream pie as evidence.

Many believe that the Boston cream pie was created in 1856 by Chef Mossburg Sanzian at the Parker House Hotel. Regardless of its origins, this cream-filled delicacy has grown to become a staple of Boston cuisine, being declared the city’s state pie in 1996.

Donuts

If TV has taught us anything, it is that police officers and donuts go hand in hand. But let’s be honest: You don’t really need to be an officer to enjoy a delicious donut . This tasty treat has become an instantly recognizable pop icon, with its iconic shape and many colorful frostings.

It is believed that donuts were first brought to America by Dutch settlers, who brought a similar pastry called an olykoek to New York. In time, donuts would be happily adopted by the entire country. Nowadays, millions of these treats are consumed around America every day.

Hershey’s chocolate bars

Let’s continue with " The Great American Chocolate Bar." Over 120 years ago, the very first Hershey bar was sold by American chocolatier and businessman Milton Hershey. This first bar unknowingly started one of the most lucrative and iconic chocolate companies in the world.

After that first bar sold at the start of the 20th century, Hershey has produced a myriad of iconic products, including their "Cookies ‘n’ Creme Bar" or their "Air Delight Bar." Regardless, you know that whenever you unwrap a delicious Hershey’s chocolate bar , you’ll find some of the world’s finest chocolate inside.

Cobbler

Let’s face it; the word " cobbler " is an awful-sounding word for such a delicious treat. Not only that, historians can’t seem to agree on where this name comes from. Many believe that it is a variant of the verb "to cobble", while others state that it comes from its resemblance to a ‘cobbled’ stone pathway. But we digress: Let’s instead just focus on how delicious they are.

Although originally created in the United Kingdom, cobblers are particularly popular in America, with many states and regions having their very own special variants. American cobblers are literally too many to mention, so we’ll just highlight a few of our favorites, like the "Brown Betty" (made with fruits and sweetened crumbles) or the "apple pan dowdy".

M&Ms

We’ll end this article with one of America’s most iconic pieces of candy. At first glance, M&Ms are deceptively simple: They are just small and colorful pieces of chocolate. However, as anyone who has eaten a handful of M&Ms will tell you, there’s something magical to these small yet wonderful sweet treats.

M&Ms were created in 1941, inspired by a similar British product called "Smarties". The two Ms featured in the name come from Forrest Mars Sr., who created the product, and Bruce Murrie, stakeholder and son of Hershey Chocolate’s president.
