By the end of 1499 the city of
Segovia founded the location of Navalcarnero, to put an end to the conflicts around the area. Since 1480 (when the
Catholic Monarchs disposed of the
sexmos of Valdemoro and Casarrubios), the territory had been progressively occupied by the
vassals of the Marquis of Moya and those of Comendador don Gonzalo Chacón. On 10 October 1499 the first Mayor of Navalcarnero was elected from the six residents of
Perales that founded the village. Shortly after its foundation, in 1521, Alonso de Arreo,
alderman and
barrister of Navalcarnero helped Segovia in the
Castilian War of the Communities. Navalcarnero was under Segovian jurisdiction until 1627 (128 years), during which it was attacked several times and burned four times by the nearby domains. The city held a lawsuit against the Marquisate of Moya that lasted 93 years for the property of the Marimartín meadows. It also protected the rest of the municipality from don Gonzalo Chacón and his descendants for 118 years (until 1617). In 1627 the municipality bought its own jurisdiction to the Crown, becoming an independent city; it kept, however, the Segovian
coat of arms in its own.

John Whitaker, reporter for the
New York Herald Tribune interviewed
Mohamed Mizzian, a
Moorish general of the
Nationalists, and reported on Mizzian giving two captured teenage girls, one found with a trade-union card, to some forty of his troops for
mass rape near Navalcarnero. Whitaker described how Mizzian "smirked when I remonstrated with him. 'Oh, they'll not live more than four hours,' he said". In 1937, during and after the
Battle of Jarama, captured
Republican troops were held in Navalcarnero jail. Sixteen British
International Brigade soldiers were interrogated, fingerprinted and had their heads shaved there before being paraded standing on the back of a truck guarded by members of the
Civil Guard and filmed by
Movietone News. They were held, nine to a cell, for four days before transfer to a prison in
Talavera de la Reina. ==Transportation==
