Then the small fishermen dwelling grew up and became a village, which was called “Vila do Poty”, but, due to the inundation of the Parnaíba River riverbanks, the city had to be built in a higher position. In the 19th century, it was initially called "Vila Nova do Poty", but later the city was renamed Teresina, in honor of the Empress Teresa Cristina, the wife of the Emperor of Brazil, Pedro II.
