Legal drinking age

Image: Elevate

When was the first time you tried a beer? Probably at 21 or later. While that's completely normal here in the US, it can seem a bit strange to people in other parts of the world. Why? In America, you can vote, serve on a jury, and even get married in some states at 18, but you still can't legally buy alcohol until you're 21. In many other countries, the legal drinking age is 18—or even younger—and that's why they find our law unusual.

The faces of real estate agents

Image: Tierra Mallorca

We're used to walking through a neighborhood and seeing signs with real estate agents' faces in front of homes for sale. But in other countries, that's pretty unusual! In many places, real estate transactions are more impersonal; you deal with an agency, not a specific person. Here in the US, we like to put a face to the name. Getting to know the person helping you buy or sell a home feels more personal and trustworthy. It makes sense, right?

Our coins

Image: Shot by Cerqueira

Many of us don't even notice this until we travel abroad, but some of our coins don't actually show their value! Sure, you'll see words like "Five Cents," "One Cent," or even "One Dime," but there's no actual number printed on them. When you think about it, that's kind of strange, right? Especially when most countries display the value on their coins using numbers.

American flag everywhere

Image: camera obscura

In many countries, their national flag is used only for formal or official purposes, but that's not the case in the US. We tend to see the American flag literally everywhere, not just at official functions or holiday celebrations, but also on all kinds of products and imagery. From T-shirts and caps to food packaging and even swimsuits, our flag is a constant presence in everyday life.

No bad words on TV

If you're in America and turn on your TV right now, you'll find everything from romantic scenes to shows about zombies or violent crimes, but you'll rarely hear any bad language. Our television generally doesn't include insults or swear words, while in other countries they often do, even in shows that air during times when children might be watching.

Dinner before 8 PM

Image: Or Hakim

Depending on the region, dinner in the United States is often served before 8 p.m., and sometimes even before 7 p.m. But in many other countries, that's considered too early. In Latin America, for example, most people eat dinner between 8 and 11 p.m.!

The Imperial System

Image: Jarosław Kwoczała

We Americans use miles, feet, pounds, and degrees Fahrenheit, but this is often very confusing for visitors from other parts of the world. We are totally used to the Imperial System, but in most countries, the Metric System reigns supreme, with everything measured in meters, kilometers, kilograms, and degrees Celsius.

Big portions

Large portions are deeply ingrained in our daily lives. Whether it's restaurant meals, snack packs, or soft drinks, everything tends to be bigger in America. This can be surprising for foreigners who come here and order food, since in many other countries, dishes are smaller, and the custom of taking leftovers home after eating at a restaurant isn't as common as it is in the US.

Turkey pardon

The pardoning of the turkey by the US president is a big event for many Americans. But in other parts of the world, where Thanksgiving isn't celebrated, it can come as a surprise. To foreigners, this formal ceremony involving a turkey might seem quite strange. Since Thanksgiving traditions aren't part of their history, this custom is uniquely American.

Alumni homecoming

Perhaps you've had the chance to participate in Homecoming, the annual event that celebrates university spirit with parties, sports games, and other activities for students returning to campus. While it's a big part of our college tradition and communities are deeply involved, it's quite different in other parts of the world, where the return to school usually happens with little fanfare.

1851: Early refining emerges

Image: Cedrik Wesche

Just before the drilling boom, chemists like Samuel Kier developed small stills to refine crude oil into kerosene for lamps.

That innovation turned oil from a curiosity into a practical commodity. Kerosene replaced whale oil, making lighting cheaper and more widely available, and it created demand for a reliable crude supply.

1859: First commercial well

Image: Provincial Archives of Alberta

On August 27, 1859, Drake Well near Titusville, Pennsylvania, drilled by Edwin L. Drake, became the first purposefully drilled commercial oil well in U.S. history.

This moment ignited the first true American oil boom. Suddenly, it was possible to produce large volumes of crude—not just collect surface seepage—and to refine it into useful fuels.

1860s–1870s: Pennsylvania oil rush

Image: Jeff W

Word of the Drake success spread fast, and drilling spiked throughout Pennsylvania. Towns such as Titusville swelled almost overnight as wells and refineries spread along Oil Creek Valley.

Railroads extended into western Pennsylvania to transport oil across the country, embedding petroleum into America’s emerging industrial infrastructure.

1890s: Dawn of the automobile

Image: Matthew Lancaster

By the 1890s and into the early 20th century, the rise of the automobile created growing demand for gasoline , which had previously been a relatively minor byproduct of crude oil refining.

This shift moved oil’s primary role away from lighting and industrial lubrication and toward transportation fuel , setting the stage for petroleum to dominate America’s energy needs in the decades that followed.

1900s–1910s: Rise of big oil companies

Image: Russel Bailo

Following early successes, oil refining and distribution consolidated. Firms like Standard Oil Company rose to dominate refining, pipelines, and distribution networks.

At the same time, new oil fields and competition still challenged monopolies and spread oil wealth and infrastructure across more regions of the country.

1914–1945: Oil & war

Image: Roman

During both World War I and World War II, U.S. oil production and refining capacity became critical to the Allied war effort , fueling ships, vehicles, aircraft, and manufacturing.

That strategic role cemented oil’s position not only in industry but also in American global power, military strategy, and foreign policy.

1960: A global oil cartel forms

Image: Christian Harb

On September 14, 1960, the main oil‑exporting nations formed the Organization of the Petroleum Exporting Countries (OPEC) to coordinate oil production and influence prices globally.

Though initially limited in power, OPEC’s rise began to challenge American dominance , setting the stage for decades of geopolitical tension around oil supply.

1969: Santa Barbara oil spill

Image: matt brown

In early 1969, a blowout from an offshore drilling platform released tens of thousands of barrels of oil into the waters off California’s coast, devastating marine life and beaches.

The resulting public outrage helped trigger a surge in environmental awareness and regulation, marking a turning point in how the oil industry was perceived socially and politically.

1970–1973: Peak and decline

Image: Documerica

By 1970, U.S. conventional oil production reached its peak, but soon after began a decline as domestic fields matured and couldn’t keep up with the growing demand.

As American production fell, the country gradually became more reliant on foreign oil, a shift that would have major economic and political repercussions.

2000s–2010s: Top oil producer again

Image: engin akyurt

In the early 2000s, engineers refined techniques like hydraulic fracturing and horizontal drilling. This unlocked vast shale‑oil and shale‑gas reserves previously uneconomical to tap.

From about 2010 onward, U.S. crude oil production rose sharply, reversing decades of decline. By 2019, the country was producing at levels not seen since the early 1970s.

Martha Washington

Let’s begin with the inaugural first lady of our country. In May 1789, Martha Washington inaugurated the role of First Lady of the United States when she arrived in New York City to meet her husband, George Washington. Interestingly, the name "First Lady" wouldn’t be used until some time later. Instead, Martha was simply referred to as "Lady Washington".

As you would expect, Martha Washington installed practices that went on to become traditions held by many future First Ladies, including receptions to the general public on New Year’s Eve. Furthermore, President Washington asked Martha to hold special drawing room events at their residence. These social gatherings became instrumental in forming what was known as the "Republican Court" , an influential group of American intellectuals and politicians.

2

Rosalynn Carter

According to Rosalynn Carter , she first became attracted to her husband, future president Jimmy Carter, when she saw him in a photograph dressed in his U.S. Navy uniform. What followed is a long and prosperous love story, which only ended in 2023 after Rosalynn passed away at the age of 96 years old.

During her tenure as First Lady, Rosalynn became an advocate for mental health and women’s rights, and she continued to support these causes through her work in the Carter Center. Both Rosalyn and President Carter were awarded the Presidential Medal of Freedom in 1999.

3

Barbara Bush

Few First Ladies hold the honor of being both the wife and the mother of a U.S. President, and Barbara Bush is one of them. She served as the First Lady during the presidency of George H. W. Bush, who acted as the 41st U.S. President from 1989 to 1993.

Although she presented herself in an almost apolitical manner, Barbara often engaged in charity work, most notably in campaigns to fight illiteracy. After her husband’s presidency ended, she continued to work in campaigning for her sons, including our 43rd President, George W. Bush.

4

Eleanor Roosevelt

Eleanor Roosevelt is remembered as the longest-serving First Lady in U.S. history. However, the legacy of this amazing figure is not limited to this fact. Roosevelt is considered to be one of the most groundbreaking First Ladies in history, completely revolutionizing the function.

Roosevelt took an active role during her husband’s terms, actively engaging in public events, travels, and cultural activities. Not only that, she was instrumental in President Roosevelt’s involvement with the then-newly formed United Nations. Eleanor served as a delegate to the U.N. General Assembly, acting as the leading figure behind the drafting of the Universal Declaration of Human Rights.

5

Nancy Reagan

Just like her husband, Nancy Reagan’s career before the White House was filled with the glamour and excitement of Hollywood. Between the 1940s and 1950s, she starred in several blockbusters such as "The Next Voice You Hear...", "Night into Morning", and "Donovan ’ s Brain", acting under her maiden name, Nancy Davis.

In 1952, she married then-fellow actor Ronald Reagan, the president of the Screen Actors Guild at the time. Nancy first served as First Lady of California when her husband was governor of the state, and later on as First Lady of the country in 1981.

6

Lady Bird Johnson

Some First Ladies (although not many) are better known by their nicknames, and that’s certainly the case with " Lady Bird" Johnson . Born Claudia Alta Taylor in Karnack, Texas, this First Lady’s nickname comes from the fact that her nursemaid apparently stated that young Claudia was "as pretty as a ladybird".

When she was in her early 20s, Lady Bird met a young congressional aide named Lyndon B. Johnson after a mutual friend introduced them. The First Lady would later declare that she felt "like a moth drawn to a flame" on that first meeting. A few weeks after their first dates, the couple married and went on to have two daughters, Lynda Bird and Luci Baines.

7

Jackie Kennedy

For many Americans, First Ladies are the pinnacle of glamour. Their impeccable manners and warm personalities perfectly match their classy outfits. In that sense, Jacqueline "Jackie" Kennedy is considered to this day an international icon, known for her daring yet elegant attire and her devotion to their family and her country.

Jackie met President Kennedy, then U.S. Representative for Massachusetts, at a dinner party held by journalist Charles L. Bartlett. A year later, in 1953, the couple married in an event that was listed as the social event of the season. Jackie took a rather active role in her duties as First Lady. She conducted a massive restoration process of the White House and often joined her husband on many trips abroad, becoming a beloved cultural ambassador for America.

8

Hillary Clinton

Hillary Clinton is definitively the person on this list with the most political experience. She was Secretary of State, Senator for the State of New York, and presidential candidate. However, we shouldn’t overlook the fact that she dutifully served as First Lady of the United States while her husband was in the White House.

While the world knew her as Hillary Rodham, she entered Yale Law School in the early 70s, where she met a fellow law student by the name of William "Bill" Clinton. They married in 1975 and welcomed their only daughter, Chelsea, in 1980.

9

Michelle Obama

Following her graduation from Princeton University, a young lawyer by the name of Michelle LaVaughn Robinson started working in a Chicago law firm, focusing on marketing and intellectual property law. During her time in this office, she met another young lawyer named Barack Obama. Did any of them know that they were meeting their future spouse?

Let’s now jump to the year 2009: Barack Obama was the first African-American President of our country, and Michelle Obama became the First Lady of the United States. During her time in the White House, Michelle took a stand against many difficulties, like poverty, childhood obesity, and illiteracy.

10

Betty Ford

Elizabeth Anne "Betty" Ford assumed the role of Second Lady when her husband, Gerald Ford, served as Vice President to Richard Nixon (1973-1974), and she became the First Lady when Nixon resigned from the presidency in August 1974.

However unexpected her rise to the role was, Betty Ford is fondly remembered as one of the most courageous First Ladies of our country; she was not afraid to speak her mind and get involved in politics. During her time in the White House, she became known as a passionate defender of the Equal Rights Amendment, as well as a public spokesperson for breast cancer awareness.
