Historical Key West Timeline – Pirates, Shipwrecks & more
Key West looks like nothing but sun, bars, and sunsets at first glance—but underneath the party vibe is one of the densest little history stories in the United States.
Indigenous burial island, Spanish outpost, wrecking capital, cigar boomtown, naval base, writer’s haven, and finally the tongue-in-cheek “Conch Republic”…this tiny 2-by-4-mile island has worn a lot of hats.
Our timeline of Key West history focuses on the major events that actually shaped the island’s growth, from the first European contact through hurricanes, boom years, bust years, and modern tourism.
Events in Key West History
Key West Before Europeans: Calusa, Tequesta & “Bone Island”
Long before anyone called it Key West, the island was part of the world of the Calusa and Tequesta peoples.
Archaeology and early Spanish accounts suggest that Indigenous groups used the island and surrounding Keys as seasonal fishing and shell-gathering grounds, and likely as a burial site—leaving the bones that later inspired the name Cayo Hueso (“Bone Island”).
By the time Europeans arrived, disease, slave raids, and warfare were already taking a terrible toll on Florida’s native nations.
Over the 1600s and 1700s, the remaining Calusa and related groups were gradually pushed out or evacuated to Cuba, leaving the Keys with no large permanent Indigenous settlements by the late 1700s.
Key West History Timeline
Below is the streamlined Historical Key West history timeline, formatted for easy reading by Florida Travel Blog visitors.
Indigenous & Colonial Era (Before 1821)
c. 800–1500 – Indigenous Calusa and related peoples inhabit and use the lower Florida Keys, including present-day Key West, as fishing grounds and burial areas. Their presence and burial sites later inspire the Spanish name Cayo Hueso (“Bone Island”).
1513 – Spanish explorer Juan Ponce de León sails through the Florida Keys on his voyage of discovery, likely sighting the island that will become Key West. He claims Florida and the Keys for Spain; sailors begin using the term los Martires for the archipelago and later Cayo Hueso for this island.
1521 – Ponce de León returns to colonize southwest Florida and clashes with the Calusa; he is mortally wounded, and Spain’s attempts at permanent colonization in South Florida largely stall. Indigenous control of the Keys continues, though Spanish ships, missionaries, and fishermen pass through the area.
1600s–1700s – Spain intermittently uses Cayo Hueso and nearby islands as fishing and salvage bases. A small garrison and fishing village exist at times, but disease and conflict drastically reduce local Indigenous populations.
1711 – Spanish authorities evacuate roughly 270 remaining Indigenous people (mainly Calusa and related groups) from the Keys to Cuba. Many die shortly afterward, marking the near-end of Native communities directly tied to Cayo Hueso.
1763 – The Treaty of Paris transfers Florida from Spain to Britain. The last documented Native residents of Key West are taken to Cuba, and the island essentially loses its permanent population. The surrounding Keys are used only seasonally by fishermen and wreckers.
Late 1700s – Bahamian “Conch” settlers and Cuban fishermen regularly camp on Cayo Hueso to fish, catch turtles, cut hardwood timber, and salvage ships wrecked on the coral reef. Smugglers and privateers also use the island for hiding and repairs—early hints of the wrecking economy that will later make Key West rich.
1783 – Britain returns Florida to Spain at the end of the American Revolutionary War. Cayo Hueso remains a remote frontier island, visited by mariners but with no fully organized town.
1815 – The Spanish governor in Havana grants Cayo Hueso (Key West) to Juan Pablo Salas, a Spanish artillery officer, as a reward for his service—creating the deed that will later be sold to American investors.
1818 – New England fishermen begin using parts of the Keys more frequently after the War of 1812. American commercial interest in the Straits of Florida and Key West grows as shipping increases through the area.
1819 – The Adams–Onís Treaty is signed. Spain agrees to cede Florida to the United States, setting the stage for formal American control of Key West and the rest of the Keys.
1821 – Spain formally transfers Florida to the United States. Juan Pablo Salas sells his rights to Key West to several parties, but John W. Simonton, a Mobile merchant, secures the controlling claim—paving the way for American settlement and development.
Wreckers, Wealth & War (1820s–1890s)
1822 – U.S. Navy Lieutenant Matthew C. Perry arrives, plants the American flag, and declares Key West a U.S. territory and Port of Entry. The Navy establishes an anti-piracy base, turning the island into a key outpost for suppressing piracy in the Straits of Florida.
1823 – Commodore David Porter brings the West Indies Squadron to Key West, aggressively pursuing pirates and privateers from the Keys. The Navy presence helps make sea lanes safer—and ensures more salvage business flows through Key West.
1828 – Key West is officially incorporated as a city. A federal court with admiralty jurisdiction is established, centralizing wrecking and salvage cases on the Florida Reef, and channeling huge wealth into the town.
1831 – The first cigar factory opens in Key West, launching what will become one of the island’s major industries and attracting skilled Cuban cigar makers.
1832 – A lighthouse is built on nearby Sand Key (about 7 miles south, and later another on Key West itself), to guide ships safely around the reef—a paradoxical move that both protects mariners and gradually reduces the easy profits of wrecking.
1836 – During the Second Seminole War, Key West serves as a military staging area and refuge. Troops move through the island, reinforcing its strategic importance to the U.S. in Florida.
1846 – The Great Havana Hurricane slams the Keys, destroying many structures and severely damaging the early lighthouse. The storm spurs new lighthouse construction and federal investment in coastal defenses.
1847 – Construction begins on Fort Zachary Taylor, a massive brick fort guarding the harbor entrance. It will later play a major role during the Civil War and is now a state park and popular beach.
1851 – The Key West Lighthouse keeper’s quarters and related structures are completed; lighthouse operations become central to both safety and salvage along the reef.
1861 – The Civil War begins. Though Florida joins the Confederacy, Key West remains under Union control throughout the war. Fort Taylor and other installations help enforce the Union blockade of Confederate shipping. Key West emerges with its Union loyalty intact and its economy poised to benefit from peacetime shipping, fishing, and cigar production.
1870s – Wrecking, sponging, and fishing fuel rapid growth. By the 1830s–1850s, Key West is often described as the wealthiest city per capita in the United States, thanks largely to salvage profits and cigar exports.
1886 – A devastating fire sweeps through much of Old Town, destroying homes and businesses. Rebuilding leads to many of the classic Conch houses visitors see today.
1889 – An overseas telegraph line connects Key West to the mainland, shrinking the island’s isolation and tightening its role in Caribbean and Gulf communications.
1890s – The cigar industry peaks—factories in Key West produce more than 100 million cigars annually, drawing thousands of Cuban workers and making the island a hotbed of Cuban revolutionary politics.
1898 – During the Spanish–American War, Key West becomes a major staging base for U.S. naval operations headed to Cuba, just 90 miles away. The sinking of the USS Maine and wartime troop movements bring intense activity to the harbor.
Railroads, Hurricanes & Reinvention (1900–1945)
1900s – As navigation improves and wrecking declines, sponge fishing and commercial fishing expand. Key West’s economy begins to diversify, though it remains vulnerable to storms and market swings.
1906–1912 – Industrialist Henry Flagler builds the Overseas Railroad, extending the Florida East Coast Railway all the way to Key West. Completed in 1912, it’s hailed as the “Eighth Wonder of the World” and turns Key West into a rail-connected deep-water port.
1919 – Prohibition begins. With Cuba only a short sail away, rum-running and smuggling flourish through the Keys, adding a new illicit layer to the island’s economy.
1928 – Writer Ernest Hemingway arrives in Key West for the first time to pick up a Ford car that’s late in delivery. Stranded for weeks, he falls in love with the island and completes work on A Farewell to Arms—beginning Key West’s literary legend.
1931–1939 – Hemingway and his wife Pauline live in the now-famous Hemingway House on Whitehead Street, giving Key West a permanent link to one of America’s most famous authors.
1935 – The catastrophic Labor Day Hurricane devastates the Middle Keys and destroys long stretches of the Overseas Railroad. More than 400 people die in the Keys; the railroad is never rebuilt.
1938 – The ruined railroad bridges are converted into the Overseas Highway (U.S. 1), giving Key West road access to the mainland for the first time and opening the door to modern auto tourism.
1942 – During World War II, Key West becomes a major naval and air base for anti-submarine patrols and coastal defense. Military investment reshapes the island and brings an influx of service members who later return as retirees.
1947 – President Harry S. Truman makes his first visit to the Little White House in Key West, beginning a long relationship between the island and the presidency. The house becomes a Cold War retreat and now a historic site.
Modern Key West: Tourism, Culture & the Conch Republic (1950s–Present)
1950s – Shrimping and commercial fishing grow, while the cigar industry shifts toward Tampa. Key West increasingly leans on tourism, military spending, and its quirky island culture.
1961–1962 – After the Cuban Revolution and during the Cuban Missile Crisis, Key West again becomes a strategic Cold War outpost, with heightened military alert and waves of Cuban refugees passing through the island.
1970s – Preservation efforts ramp up in Old Town, saving historic Conch houses and Victorian structures. Key West begins to consciously market its architecture, laid-back atmosphere, and LGBTQ+-friendly culture.
1978 – Fantasy Fest is launched as a fall festival, helping extend tourism beyond the winter high season and putting Key West on the map for over-the-top costumes and nightlife.
1982 – After the U.S. Border Patrol sets up a roadblock on the Overseas Highway near the Keys, locals protest by symbolically declaring independence as the Conch Republic. The stunt becomes a beloved annual celebration and a core part of Key West identity.
1986 – Treasure hunter Mel Fisher completes major recovery of gold and silver from the 1622 Spanish galleon Nuestra Señora de Atocha. Artifacts displayed in Key West’s Mel Fisher Maritime Museum add another layer of shipwreck lore to the town.
1998 – The waters around Key West become part of the Florida Keys National Marine Sanctuary, adding federal protections to surrounding reefs and marine life.
2005 – Hurricane Wilma sends a significant storm surge across Key West, flooding large parts of the island and underscoring its vulnerability to tropical storms and sea-level rise.
2017 – Hurricane Irma causes major damage throughout the Keys. Key West avoids the worst of the destruction seen in the Middle Keys but still faces serious cleanup and rebuilding.
2020 – The COVID-19 pandemic shuts down tourism temporarily. Cruise traffic stops, Duval Street quiets, and the island gets a rare pause from crowds.
2020–2021 – Key West voters approve cruise-ship limits aimed at reducing large-ship calls and protecting water quality; the Florida Legislature later passes laws limiting local control over seaport regulations, sparking an ongoing debate about tourism, environment, and home rule.
2024 – Florida designates State Road A1A as the Jimmy Buffett Memorial Highway from Key West to the Georgia line. Key West hosts a celebration and sign-unveiling, honoring Buffett’s deep ties to the island and the road that inspired his album A1A.

FAQs About Key West History
What is the history of Key West?
Key West began as an Indigenous fishing and burial island used by Calusa- and Tequesta-related peoples, then became a Spanish outpost known as Cayo Hueso (“Bone Island”). In 1821, after Spain ceded Florida to the United States, American merchants bought the island; the Navy established a base in 1822, and Key West grew into a wrecking, cigar, and military town before reinventing itself as a bohemian, tourist, and cruise-ship destination in the 20th century.
Who were the first people to live in Key West?
Long before Europeans arrived, the lower Florida Keys, including present-day Key West, were used by Indigenous peoples such as the Calusa and Tequesta for fishing, shell gathering, and likely burials. Their remains and burial sites are believed to be the reason early Spaniards called the island Cayo Hueso, or “Bone Island.”
When did Key West become part of the United States?
Key West became part of the United States when Spain ceded Florida under the Adams–Onís Treaty; the transfer took effect in 1821. That same year, Spanish grantee Juan Pablo Salas sold his claim to American merchant John W. Simonton, who helped bring in U.S. naval and commercial interests that launched the modern city.
When was the City of Key West officially incorporated?
Key West was officially incorporated as a city on January 8, 1828, just a few years after the U.S. Navy established its base there. Incorporation formalized local government and courts, which was crucial for managing the profitable wrecking and shipping business in the surrounding waters.
Why is Key West called Key West, and what does “Cayo Hueso” mean?
The original Spanish name Cayo Hueso means “Bone Island”, referring to human bones found on the island, probably from Indigenous burial grounds. English speakers misheard or reshaped the name over time—“Cayo” sounds like “Key,” and “Hueso” was mistaken for “West”—so the island became known in English as Key West, the westernmost of the main inhabited Keys.
Why is Key West called the Conch Republic?
In April 1982, after the U.S. Border Patrol set up a checkpoint on the Overseas Highway that hurt the Keys’ tourism, Key West staged a tongue-in-cheek “secession” and declared itself the Conch Republic. The symbolic protest drew media attention, the checkpoint was removed, and the Conch Republic has lived on as a humorous but proud symbol of the Keys’ independent streak and unique island identity.
Why was Key West once considered the richest city per capita in the United States?
In the mid-1800s, Key West became wealthy thanks to wrecking, the legal salvage of ships that wrecked on nearby reefs. Cargo and vessels brought into Key West were sold under admiralty law, and local wreckers and merchants took a share, making so much money that the island was widely described as the richest city per capita in the nation.
What role did Key West play in the Civil War?
Although Florida joined the Confederacy, Key West stayed under Union control throughout the Civil War. Fort Zachary Taylor and other installations served as key bases for the Union blockade in the Gulf of Mexico, helping intercept Confederate shipping and reinforcing the city’s long-term identity as a strategic U.S. naval outpost.
How is Key West connected to Cuban history and the cigar industry?
Key West became a major center for Cuban cigar making in the 19th century, with factories rolling “clear Havana” cigars from imported Cuban tobacco. Waves of Cuban exiles and workers settled on the island, and the San Carlos Institute, founded in 1871, became a key gathering place where Cuban patriot José Martí helped organize the movement for Cuban independence from Spain.
What was Henry Flagler’s Overseas Railroad, and how did it change Key West?
In the early 1900s, industrialist Henry Flagler extended his Florida East Coast Railway over 100 miles of bridges and causeways to create the Overseas Railroad, which reached Key West in 1912. The rail line connected the island directly to the U.S. mainland, boosted trade and tourism, and turned Key West into a deep-water rail–seaport hub until the 1935 Labor Day Hurricane destroyed much of the line; the route was later repurposed as today’s Overseas Highway (U.S. 1).
What is the Little White House in Key West, and which presidents used it?
The Harry S. Truman Little White House began as a naval officers’ residence in 1890 and later served as President Truman’s winter White House, where he spent 175 days over 11 working vacations between 1946 and 1953. Other presidents who have used or visited the house include William Howard Taft, Dwight Eisenhower, John F. Kennedy, Jimmy Carter, and Bill Clinton, making it one of the most historically significant buildings in Key West.
What major hurricanes have shaped the history of Key West?
Several powerful storms have marked Key West’s history, including the 1846 Havana Hurricane, which destroyed early lighthouses and many buildings; early-1900s storms that battered Flagler’s railroad; the 1935 Labor Day Hurricane that wrecked much of the Overseas Railroad; and later hurricanes like Wilma (2005) and Irma (2017), which caused widespread flooding and damage. Each storm prompted rebuilding, changes in infrastructure, and new chapters in the island’s resilience story.
What is Key West best known for today from a historical perspective?
Historically, Key West is best known for its role as a wrecking and naval town, its 19th-century cigar and Cuban-exile community, its ties to writers like Ernest Hemingway, its symbolic secession as the Conch Republic, and its preserved Old Town full of Conch houses, forts, and museums. Modern visitors can still see all those layers in places like Fort Zachary Taylor, the Shipwreck Museum, the San Carlos Institute, the Hemingway House, and Truman’s Little White House.
