HistoryA character grade: shown, never part of North Port’s overall grade.
Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so North Port’s 0.4 sits above most of its state (69% of Florida towns have fewer) while its 3 listings outnumber those of 65% of U.S. towns.

Archaeological digs at the Little Salt Spring show that what is now North Port was inhabited by pre-Columbian Native Americans. Evidence of their existence includes projectile points, a carved oak mortar, and a piece of a nonreturnable wooden boomerang.
In 1954, the Mackle Brothers started the General Development Corporation (GDC) with the intention of selling property in Florida to northerners. Not only would they plat and sell a majority of what is now North Port, the company's employees served on the city's first council. The city itself was incorporated in 1959. The city was incorporated with 21 residents, most of whom were GDC employees, in order to bypass county regulations related to infrastructure.
