History for the Florida Keys

  • The first inhabitants of the Florida Keys were the Native American tribes Calusa and Tequesta. Juan Ponce de Leon discovered them.

  • When Spaniards found the archipelago they  thought these islands seemed twisted and tortured which explains why they named them Los Martires meaning “the martyrs.”

  • During the next years, a lot of ships from Spain used to pass close to their coasts loaded with gold from Central America. This made the islands the perfect home base for pirates that were preying on those galleons.

  • In their early days, Key West and the Florida Keys were a major part of the area’s wrecking industry – an industry associated with the frequent shipwrecks in the area.

  • In 1812, all of Florida including the Keys officially became the territory of the United States.

  • The first formal settlement appeared in the 1820s in Key West.

  • By the early 1900s its prosperity began to decline as better navigational techniques reduced area shipwrecks.

  • Settlers began to arrive and make their home at Cayo Hueso or what is now Key West in 1822.

  • In 1935 a hurricane hit the area and destroyed the railway, so an overseas highway was built to replace it.

  • Fort Zachary Taylor, initiating Key West’s long history with the US military. Fort Taylor was an army base until the 1940s when it was turned over to the Navy.

  • Beginning in the late 1970s construction began on a new bridge to connect the Florida Keys. This bridge is known today as the Seven Mile Bridge and it connects Knights Key in the Middle Keys to Little Duck Key in the Lower. In March 2008 however, this bridge was closed to traffic as it was deemed unsafe and construction later began on a new bridge.
