History of Saint Martin
Early history 
Ancient relics date the island's first settlers, probably Ciboney Indians (a subgroup of Arawaks), back to 3,500 years ago. Then another group of Arawaks migrated from South America's Orinoco basin around 800 A.D. Because of St. Martin's salt-pans they called it “Soualiga,” or “Land of Salt.” Mainly a farming and fishing society, the Arawaks lived in villages of straw-roofed buildings which were strong enough to resist hurricanes. Their tranquil civilization valued artistic and spiritual pursuits.
Their lives were turned upside-down, however, with the descent of the Carib Indians from the same region they had come from. A warrior nation, the Caribs killed the Arawak men and enslaved the women. When Europeans began to explore the Caribbean, Carib society had almost completely displaced the Arawaks.
Colonial Era 
In 1493, on Christopher Columbus second voyages to the West Indies, upon first sighting the island he named it Isla de San Martín after Saint Martin of Tours because it was November 11, St. Martin Day. However, though he claimed it as a Spanish territory, Columbus never landed there, and Spain made the settlement of the island a low priority.
The French and Dutch, on the other hand, both coveted the island. While the French wanted to colonize the islands between Trinidad and Bermuda, the Dutch found San Martín a convenient halfway point between their colonies in New Amsterdam (present day New York) and Brazil. With few people inhabiting the island, the Dutch easily founded a settlement there in 1631, erecting Fort Amsterdam as protection from invaders. Jan Claeszen Van Campen became its first governor, and soon thereafter the Dutch East India Company began their salt mining operations. French and British settlements sprang up on the island as well. Taking note of these successful colonies and wanting to maintain their control of the salt trade, the Spanish now found St. Martin much more appealing. The Eighty Years' War which had been raging between Spain and the Netherlands provided further incentive to attack.
Spanish forces captured Saint Martin from the Dutch in 1633, seizing control and driving most or all of the colonists off the island. At Point Blanche, they built Old Spanish Fort to secure the territory. Although the Dutch retaliated in several attempts to win back St. Martin, they failed. Fifteen years after the Spanish conquered the island, the Eighty Years' War ended. Since they no longer needed a base in the Caribbean and St. Martin barely turned a profit, the Spanish lost their inclination to continue defending it. In 1648, they deserted the island.
With St. Martin free again, both the Dutch and the French jumped at the chance to re-establish their settlements. Dutch colonists came from St. Eustatius, while the French came from St. Kitts. After some initial conflict, both sides realized that neither would yield easily. Preferring to avoid an all-out war, they signed the Treaty of Concordia in 1648, which divided the island in two.
A legend grew up around the division of the island. According to legend, in order to decide on their territorial boundaries, the two sides held a contest. It began with a Frenchman drinking wine and a Dutchman drinking jenever (Dutch gin). When both had sufficiently imbibed, they embarked from Oysterpond on the island's east coast. The Frenchman headed off along the coast to the north, while the Dutchman followed the coast south; wherever the two groups met was where they would draw the dividing line from Oysterpond. But as the Dutchman met a woman and stopped to sleep off the effects of the gin, the Frenchman was able to cover more distance, but apparently also cheated as he cut through the northeastern part of the island, and therefore ended up with more land.
Though oft-repeated, the story is not historically accurate. During the treaty's negotiation, the French had a fleet of naval ships off shore, which they used as a threat to bargain more land for themselves. In spite of the treaty, relations between the two sides were not always cordial. Between 1648 and 1816, conflicts changed the border sixteen times. In the end, the French came out ahead with 21 square miles (54 km2) to the 16 square miles (41 km2) of the Dutch side.
Although the Spanish had been the first to import slaves to the island, their numbers had been few. But with the new cultivation of cotton, tobacco, and sugar, mass numbers of slaves were imported to work on the plantations. The slave population quickly grew larger than that of the land owners. Subjected to cruel treatment, slaves staged rebellions, and their overwhelming numbers made them impossible to ignore. On July 12, 1848, the French abolished slavery on their side of St. Martin. The Dutch followed suit fifteen years later.
Into the 20th century 
After abolition of slavery, plantation culture declined and the island's economy suffered. In 1939, St. Martin received a major boost when it was declared a duty-free port. The Dutch began focusing on tourism in the 1950s. It took the French another twenty years to start developing their tourism industry. Currently, tourism provides the backbone of the economy for both sides of the island.
In 1994, the Kingdom of the Netherlands and France signed the Franco-Dutch treaty on Saint Martin border controls, which allows for joint Franco-Dutch border controls on so-called "risk flights". After some delay, the treaty was ratified in November 2006 in the Netherlands, and subsequently entered into force on 1 August 2007. Though the treaty is now in force, its provisions are not yet implemented as the working group specified in the treaty is not yet installed.
