United States of America

A Country That Is Also a Continent

The United States is so large and so varied that treating it as a single destination is like treating Europe as a single destination — technically accurate, practically misleading. It spans 9.83 million square kilometres, six time zones, every terrestrial climate zone except true polar, and more miles of interstate highway (77,600) than any country has railway lines. Its 50 states include a sub-Arctic territory (Alaska), a Pacific tropical archipelago (Hawaii), a Caribbean commonwealth (Puerto Rico), and a continental landmass that by itself would be the world’s fourth-largest country.

The country’s cultural dominance is more recent and more peculiar than its geographic scale suggests. For most of its 249-year history, the United States was a peripheral republic that European powers largely ignored; it reached its current status — largest economy, dominant military, primary cultural exporter — only in the second half of the 20th century. That ascent remains the defining international story of the past 80 years, and understanding the United States in 2026 requires understanding both its newness as a superpower and its older, more provincial self-image as a nation of migrants, small towns, and competing regional traditions.

A Brief History

Before the United States

The territory of what is now the United States was home to hundreds of distinct Indigenous nations before European contact — the Cahokia urban complex near modern St. Louis had 40,000 inhabitants in 1100 AD (more than London at the time), the Iroquois Confederacy in the northeast practised a sophisticated federal governance that some American founders explicitly studied, and the Puebloan civilisations of the Southwest built multi-storey cliff dwellings still standing at Mesa Verde. The arrival of European colonists from 1492 onwards triggered demographic collapse across these societies — disease, displacement, and warfare reduced Indigenous populations by an estimated 80-90% over 200 years.

Colonial Period and Independence

English colonisation began with Jamestown (1607) and Plymouth (1620), followed by the 11 other colonies that would declare independence in 1776. The Revolutionary War (1775-1783) produced the Declaration of Independence, the Constitution (ratified 1788), and the Bill of Rights (1791) — documents whose influence on global constitutional law has been unmatched. The early republic was agrarian, slave-holding in its southern states, and geographically limited to the Atlantic seaboard and its immediate hinterlands.

Expansion and Civil War

Between 1803 and 1898 the United States expanded from 13 states to a continental nation through treaty (Louisiana Purchase from France, 1803), war (Mexican-American War, 1846-1848), negotiation (Oregon Treaty with Britain, 1846), and purchase (Alaska from Russia, 1867). Expansion was accompanied by the forced removal of Indigenous peoples (the Trail of Tears of 1838 being the best-known episode) and the entrenchment of chattel slavery in the South.

The Civil War (1861-1865) — fought over slavery and its expansion into new territories — killed roughly 620,000 Americans, more than every other war the country has fought combined. Union victory produced the 13th Amendment (abolition of slavery), the 14th Amendment (birthright citizenship, equal protection), and the 15th Amendment (voting rights regardless of race), though the full implementation of these rights required another century of civil rights struggle.

The American Century

The 20th century transformed the United States from a regional power into the dominant global economy and eventually the primary superpower of the post-1945 world. Key moments include the Roaring Twenties (the 1920s boom), the Great Depression (1929-1939), World War II, the Cold War (1947-1991), the Civil Rights Movement (1954-1968), and the technology revolution centred in California that produced the personal computer, the internet, and the major platforms now used by most of the world’s population.

Geography and Climate

The United States spans 9.83 million km² across 50 states and several territories. The contiguous 48 states form a single continental landmass from the Atlantic to the Pacific; Alaska adds an area larger than Western Europe; Hawaii contributes 137 Pacific islands, of which eight are large.

Five Major Regions

• The Northeast — New England (Maine through Connecticut), the Mid-Atlantic (New York, New Jersey, Pennsylvania), Washington DC. Historical core of the republic, densest population concentration, dominant financial and political institutions.
• The South — from Virginia through Florida, west to Texas. Cultural distinctness rooted in plantation agriculture, evangelical Christianity, and a longer history of racial conflict. Home to the largest metropolitan areas outside the Northeast (Atlanta, Dallas, Houston, Miami).
• The Midwest — the Great Lakes states plus the Great Plains. Industrial heartland (the “Rust Belt”) and agricultural breadbasket (the Corn Belt). Chicago is the regional capital.
• The West — Rocky Mountain states, Southwest, Pacific Coast. Half the country’s total land area, a quarter of its population, and nearly all of its most dramatic landscapes (Grand Canyon, Yosemite, Yellowstone, Joshua Tree, Big Sur).
• Alaska and Hawaii — two states that are ecologically and culturally distinct enough to be treated separately.

Climate Zones

The United States contains every major Köppen climate class. The Pacific Northwest (Seattle, Portland) has an oceanic climate like western Europe; the Great Plains experience a continental climate with extreme seasonal swings; Florida and Louisiana have a subtropical climate with a distinct hurricane season (June-November); the Southwest (Arizona, Nevada) is true desert with summer highs regularly above 45°C; Alaska ranges from subarctic to arctic.

Natural Hazards

The country experiences a wider range of natural hazards than almost any other — hurricanes on the Gulf and Atlantic coasts, tornadoes in “Tornado Alley” (Texas through Nebraska), earthquakes along the West Coast and in Alaska, wildfires across the West, volcanoes in the Cascades and Alaska, and severe winter storms across the northern half. Climate change has measurably intensified several of these risks in the past 30 years.

Culture and Diversity

American culture is difficult to summarise because it is less a single culture than a loose framework within which extremely varied regional, ethnic, and religious cultures coexist. The pattern most outside observers recognise — individualism, optimism, commercial dynamism, religious pluralism — applies more or less depending on where in the country one is looking.

Regional Cultures

• New England — bookish, reserved, historically Puritan, politically liberal. Universities (Harvard, Yale, MIT, Brown) set the tone.
• The South — more religious, more conservative politically, with a cuisine (barbecue, soul food, Creole, Cajun) and a musical heritage (blues, country, jazz, gospel, bluegrass) that have exported worldwide.
• The Midwest — “nice” is the cultural stereotype, and it has a basis in reality. Agricultural and industrial traditions, a civic-minded politics that has historically split between the parties.
• The West — younger, more transient, more immigrant-shaped. California alone would be the world’s fifth-largest economy if independent.

Language

English is the effective official language nationally (no federal language is designated in the Constitution). Spanish is spoken at home by roughly 13% of the population and is dominant in large portions of California, Texas, Florida, and New Mexico. Chinese, Tagalog, Arabic, Vietnamese, French, Korean, and Russian each have more than a million speakers.

Religion

The United States is one of the most religious developed countries — roughly 65% self-identify as Christian (split between Protestant denominations and Catholicism), 2% Jewish, 1% Muslim, 1% Hindu, 1% Buddhist, and a growing 30% unaffiliated (“nones”). Evangelical Protestantism concentrated in the South and Midwest shapes conservative politics; the nonreligious concentration in the Northeast and Pacific Coast shapes liberal politics.

The Economy

The United States has the world’s largest economy by nominal GDP (~$28 trillion in 2024, roughly 25% of global output), the largest consumer market, the largest stock market (NYSE + Nasdaq), and the world’s dominant reserve currency (the dollar). It is also the world’s largest producer of oil and gas (since 2018, overtaking Saudi Arabia and Russia), the largest agricultural exporter, and the largest destination for foreign direct investment.

Dominant Industries

• Technology — Silicon Valley, Seattle, Austin, New York. The major global platforms (Google, Apple, Microsoft, Meta, Amazon, Nvidia, Tesla) are all American. Tech is the largest sector of the US stock market by capitalisation.
• Finance — New York remains the world’s leading financial centre, with London in second place. The Federal Reserve, the US central bank, has effective influence over global monetary conditions.
• Healthcare and pharmaceuticals — the US is the world’s largest pharmaceutical market; half of the world’s major drug discoveries since 1960 happened here.
• Entertainment and media — Hollywood, the streaming industry, the music industry, and the video game industry all have their global centres in the United States. American cultural output is the country’s largest single export after finance and tech.
• Defence — the US military is the largest by expenditure (~$900 billion in 2024), and defence contractors (Lockheed Martin, RTX, Boeing, Northrop Grumman) are major industrial employers.

The Inequality Question

American economic dynamism coexists with some of the developed world’s starkest income and wealth inequality. Median household income is high by international standards (~$75,000), but the cost of healthcare, higher education, and urban housing has risen faster than wages for four decades. Roughly 11% of the population lives below the federal poverty line; life expectancy has declined for several recent years, an anomaly among wealthy nations.

Cuisine

American cuisine has historically been underrated internationally — partly because chain restaurants and fast food are more visible to outside observers than the country’s actual food scene. In fact, the US has one of the world’s most diverse dining landscapes, with strong regional traditions and an exceptional immigrant contribution.

Regional Traditions

• Southern food — fried chicken, biscuits with gravy, collards, grits, sweet tea, barbecue (Memphis, Kansas City, Texas, Carolina styles all distinct), shrimp and grits. The South produced three of the most globally influential American cuisines: soul food, Creole, and Cajun.
• The Northeast — New York pizza, bagels, deli sandwiches, New England clam chowder, Maine lobster rolls, Philadelphia cheesesteaks.
• The Midwest — Chicago deep-dish pizza, Chicago-style hot dogs, Wisconsin cheese curds, Minnesota’s Scandinavian-influenced hotdish.
• The Southwest — Tex-Mex (nachos, fajitas, enchiladas), New Mexican cuisine (green chile everything), Arizona Sonoran hot dogs.
• The Pacific — California cuisine’s farm-to-table movement (Alice Waters, 1970s), Pacific Northwest salmon and oysters, Hawaiian plate lunches, poke.

Immigrant Contributions

The country’s restaurant scenes in major cities — New York, Los Angeles, San Francisco, Chicago, Houston, Atlanta, Miami, Washington — are increasingly shaped by immigrant cuisines: Mexican, Chinese (especially Cantonese, Sichuan, and Taiwanese), Vietnamese, Korean, Japanese, Indian, Ethiopian, Lebanese, and increasingly West African. American-Chinese cuisine (General Tso’s chicken, orange beef, crab rangoon) is itself a distinct 20th-century tradition.

Nature and UNESCO Sites

The United States has 25 UNESCO World Heritage Sites, about evenly split between cultural and natural. Highlights include:

• Yellowstone National Park — the world’s first national park (1872), a supervolcano caldera, and home to roughly half the world’s geysers
• Grand Canyon National Park — Arizona, the best-known of American natural wonders
• Statue of Liberty — New York harbour, a French gift to commemorate the US centennial
• Mesa Verde National Park — Colorado, cliff dwellings of the Ancestral Puebloans
• Everglades National Park — Florida, the largest tropical wilderness in the US
• Independence Hall — Philadelphia, where the Declaration of Independence and Constitution were signed
• Redwood National and State Parks — California, home to the world’s tallest trees
• Hawaii Volcanoes National Park — active Kilauea and Mauna Loa volcanoes

The National Park System

The United States has 63 national parks and 424 total National Park Service units (including national monuments, seashores, and historic sites) across 85 million acres. The system was founded in 1916 and remains one of the country’s most trusted public institutions. The busiest parks — Great Smoky Mountains, Grand Canyon, Zion, Yellowstone, Yosemite — each receive 3-12 million visitors per year.

Travel Guide: Practical Information

Entry

The US uses a visa waiver program (ESTA) for citizens of 41 partner countries including most of Europe, the UK, Australia, Japan, South Korea, Taiwan, and Chile — allowing up to 90 days visa-free for tourism. All other nationalities require a B1/B2 visa obtained in advance. Entry requirements change frequently; check the US State Department website before booking.

Best Seasons

• April-June and September-early November are the most comfortable windows for most of the country.
• July-August is peak season for national parks (book months in advance) and for coastal beach destinations; inland cities (Phoenix, Las Vegas, Dallas) become extremely hot.
• Winter is the best time to visit the Southwest (Joshua Tree, Death Valley, Big Bend) and Florida; ski season in the Rockies and Sierra runs December-April.
• Hurricane season (June 1 - November 30) affects the Gulf Coast, Atlantic coast, and the Caribbean territories; risk concentrates in August-October.

Transport

• Distances are enormous. New York to Los Angeles is 4,500 km — more than Madrid to Moscow. Even regional trips (LA to San Francisco, Miami to Orlando) are 600-700 km.
• Domestic flights are the default for long distances. Fares are competitive; book 2-4 weeks ahead for best prices.
• Interstate highways — the country’s defining transport infrastructure. Rental cars are essential outside the major coastal cities.
• Public transit is world-class in New York City and adequate in Washington DC, Boston, Chicago, and San Francisco; minimal or nonexistent in most other cities.
• Amtrak passenger rail is scenic but slow and limited in coverage. The Acela corridor (Boston-NY-DC) is the one competitive route.

Budget

The United States is expensive — one of the world’s most expensive major destinations when accounting for accommodation, healthcare, and taxi/rideshare costs. Budget minimums are $150-$250 per day in major cities; $100-$150 in mid-sized cities; national park trips can be done more cheaply with camping ($25-$40/night campsites). Tipping culture is essential: 18-22% at restaurants, $1-$2 per drink at bars, $3-$5 per night for hotel housekeeping.

Cultural Etiquette

• Tipping is expected in restaurants, bars, taxis/Uber, hotels, tour guides, and hairdressers. It is not optional and not included in posted prices.
• Personal space and small talk — Americans expect more personal space in queues and more casual friendliness with strangers than most European or East Asian visitors.
• Religion and politics are topics most locals navigate carefully outside their own social circles; tread lightly until you know your audience.

Surprising Facts

1. The United States has no official language at the federal level; efforts to designate English have repeatedly failed in Congress.³
2. Alaska was purchased from Russia in 1867 for $7.2 million — roughly $150 million in 2024 dollars — in what was mocked at the time as “Seward’s Folly” but turned out to contain 20% of the country’s oil reserves.⁷
3. The US national anthem (“The Star-Spangled Banner”) was officially adopted only in 1931; before then, “Hail, Columbia” and “My Country, ‘Tis of Thee” competed for unofficial status.⁷
4. The Declaration of Independence was signed on August 2, 1776 — not July 4 as widely believed. July 4 is the date Congress approved the final text.⁷
5. Hawaii is the only US state that was an independent internationally recognised kingdom, overthrown in 1893 and annexed in 1898 in a process that US President Bill Clinton formally apologised for in 1993.⁷
6. Mississippi was the last US state to formally ratify the 13th Amendment (abolition of slavery) — it did not do so until 1995, and the ratification was not officially registered with the federal archives until 2013.⁷
