Kuskatan
Kuskatan was a confederation of Nahua-speaking Pipil city-states between the Paz and Lempa rivers in present-day western El Salvador. The cities had united by the thirteenth century.
Around 1400 a hereditary monarchy ruled from Kuskatan. Pedro de Alvarado invaded in 1524, fought at Acajutla and Tacuzcalco, then withdrew. San Salvador, founded in 1525, fell in a 1526 rising. In 1528 the Spanish stormed the Peñol de Cinacantan, breaking organized resistance; the province was considered pacified in 1539.
