Atlantic Return Corridor

Cuba lies roughly 90 miles from the Florida Keys, astride the entrance to the Gulf of Mexico — the geographic fact underpinning every later connection.

Havana developed on a protected northern bay near the Florida Straits, where the Gulf Stream aided Atlantic navigation — an obligatory stop on the maritime route to the New World.

In the second half of the 16th century Havana became the largest port in the region, the assembly point where fleets from across the Americas gathered before crossing the Atlantic.

By the 1750s Havana was the third-largest Spanish city in the Americas — more populated than Boston or New York — and a major naval and trade center.

Britain captured and occupied Havana for eleven months; Spain recovered it only by ceding Florida in the peace settlement — proof of Havana's strategic value.

In the 18th century Havana developed the most complete dockyard in the New World, and Spain reinforced it with one of the largest defensive systems in the Americas.

Toward the end of the 18th century about a thousand ships entered Havana Bay annually to load sugar and deliver overseas goods. This prosperity was built heavily on enslavement and colonial extraction — a truth the atlas states plainly.

For the year ending June 1869, total U.S. commerce with Cuba was recorded at about $77.9 million — Cuba was economically integrated with North America while still politically Spanish.

Cuba and Puerto Rico shared Spanish colonial roots and remained Spain's final major Caribbean colonies until 1898.

At the start of the 20th century between 50,000 and 100,000 Cubans moved among Havana, Tampa and Key West every year — cigar businesses, families and political organizers across one straits economy.

The Panama Canal opened in 1914, creating a direct Atlantic–Pacific route. It shifted shipping geography but Cuba remained positioned near Gulf entrances, U.S. coasts and northern Caribbean routes.
