Piauí has the shortest coastline of any of the non-landlocked Brazilian states at 66 km (41 mi), and the capital, Teresina, is the only state capital in the northeast to be located inland. The reason for this is, unlike the rest of the area, Piauí was first colonised inland and slowly expanded towards the ocean, rather than the other way around. In the southeast of the state, the National Park of Serra da Capivara is a UNESCO World Heritage Site. The park has more than 400 archaeological sites and the largest concentration of rock paintings in the world, in a landscape dominated by canyons and caatinga.
The state has many notable archaeological sites, including Serra de Capivara National Park and Sete Cidades National Park, which are rich in remains of prehistoric Paleo-Indian and sedentary-based Indigenous Brazilian complex cultures.
Early settlers in the region included Domingos Jorge Velho, from São Paulo state, who brought the first herds of cattle to the area; and Domingos Afonso Mafrense, from Portugal, who founded what is today Oeiras.
In the 17th century, many impoverished noblemen and Jesuit priests, as well as black and Amerindian slaves, settled there. The first large-scale cattle farming also arrived with these settlers. Large estate owners seeking new pastures for their livestock arrived from neighbouring states such as Bahia and Maranhão.
At the beginning of the 20th century, the principal industry of the state was stock raising, which dates from the first settlement in 1674 by Domingos Afonso Mafrense, who established a number of cattle ranges. A secondary industry was the raising of goats, which were able to stand neglect and a scanty food supply. Agricultural products were cotton, sugar and tobacco. Forest products included rubber, carnauba wax and dyewoods. Exports included hides, skins, rubber, wax, tobacco and cotton.
Teresina was the first Brazilian city to be planned. In 1852, an architect designed it, after being inspired by a chessboard. Situated at the mouth of the Parnaíba and Poti Rivers, Teresina was (and still is) known as the Green City because of the countless mango trees that line the city's streets.
The Parnaíba River forms the boundary with Maranhão throughout its entire length; the state lies almost entirely within the basin of the Parnaíba and its tributaries. Part of the state on the Atlantic coast and along the lower Parnaíba is low, swampy, and historically malarial. South of this the country rises gradually to a high plateau with open campos. This plateau region is watered by numerous tributaries of the Parnaíba, chief of which are, from south to north: the Poti, which has its source in the state of Ceará; the Longa; the Canindé and its tributary the Piauí, which is navigable for boats of one-meter draft up to Nova York, a few miles above the mouth of the Gurguéia. The river valleys are separated by flat-topped plateaus called chapadas, including the Serra Uruçui, which lies between the Uruçui-Preto and the Gurguéia, the Serra da Capivara National Park, which lies between the Gurguéia and the Piauí, and the Chapada das Mangabeiras, which forms the southwestern boundary of the state, separating the upper basin of the Parnaíba from that of the Tocantins.
The sandy soils along the Atlantic coast are home to the Northeastern Brazil restingas, low evergreen forests adapted to the nutrient-poor conditions. The lower basin of the Parnaíba is home to the Maranhão Babaçu forests, which extend westward into Maranhão. This ecoregion dominated by stands of the Babaçu palm.
The eastern portion of the state is dominated by the dry Caatingas shrublands, which extend across much of northeastern Brazil. The Cerrado savannas extend across the southwestern portion of the state, in the basins of the upper Parnaíba and Gurguéia rivers. Enclaves of Atlantic dry forests lie in basin of the Gurguéia, forming a transition between the Cerrado and Caatinga. Serra da Capivara National Park is located in the Caatinga of the south-central part of the state, and protects numerous caves with ancient cave paintings.
The climate is hot and humid in the lowlands and along the lower Parnaíba, but in the uplands it is dry with high day-time temperatures and cool nights.
According to the IBGE of 2008, there were 3,164,000 people residing in the state. The population density was 12.1 inh./km².
The last PNAD (National Research for Sample of Domiciles) census revealed the following numbers: 2,272,000 Brown (Multiracial) people (71.80%), 739,000 White people (23.36%), 145,000 Black people (4.60%), 41,000 Amerindian people (0.47%), 5,000 Asian people (0.17%), 2,000 Amerindian people (0.05%).
Piaui is one of the poorest states of Brazil. The service sector is the largest component of GDP at 60.1%, followed by the industrial sector at 27.3%. Agriculture represents 12.6% of GDP (2004). Piauí exports include essential oils 19.5%, soybeans 17.1%, woven cotton 15.1%, cashews 12.6%, crustaceans 12.4%, and leather 8.3% (2002).
Grupo Claudino is the largest industrial company with headquarters in the state. They have annual sales of around R$700 million.
Transfers from the Federal government are estimated to represent around a third of state GDP.
The state government has been involved in a number of initiatives to develop aspects of the state's economy. 10,000-18,000 hectares of land worth a reported R$50 million was given to Brasil Biodiesel, a green energy company. The company suffered a number of setbacks and in 2009 said it was selling the land. A second biodiesel company, Piauí Ecodiesel Ltda, is reported to be receiving up to R$81.1 million of investment.
The state has offered substantial tax benefits to agro-industrial companies. Bunge, Cargill and Algar now grow soy in the state. Suzano is to grow eucalyptus for pulp. These projects have been criticised by state environmental activists.  
According to research commissioned by SETUR, the state tourism authority, over one million tourists would visit Piaui in 2010. Estimates based on by CEPRO, the state statistics agency, suggest the actual figure is likely to fractional of this figure. The construction of an international airport at São Raimundo Nonato (Aeroporto Internacional Serra da Capivara) was criticised on the grounds that it could not function as an international airport because the runway was too short and because ANAC (the Federal aviation authority) was not involved in monitoring the project, so were unable to certify it as safe for international flights.
There is some mining in the state, including South America's only opal mines at Pedro Segundo. Diamonds are mined by Gema do Piauí Mineração Ltda (Gemapi) and processed in the neighbouring state of Pernambuco in a joint-venture with Gitanjali Group (India). The state has significant deposits of nickel and iron ore. João Carlos Cavalcanti, a mining entrepreneur, and GME4 own the rights to the 800 million tonne PI4 iron ore deposit. A new railway bisecting the state may make this deposit economically viable.
Share of the Brazilian economy: 0.5% (2004).
Portuguese is the official national language, and thus the primary language taught in schools, but English and Spanish are part of the official high school curriculum.

Festa Junina (Saint John Festival)
Festa Junina was introduced to Northeastern Brazil by the Portuguese, for whom St John's day, on the June 24, is one of the oldest and most popular celebrations of the year. Unlike the European Midsummer's Day, the festivities in Brazil do not take place at the summer solstice but during the tropical winter solstice. The festivities traditionally begin after the 12th of June, on the eve of St Anthony's day, and last until the 29th, which is Saint Peter's day. During these fifteen days, there are bonfires, fireworks, and folk dancing in the streets (step names are in French, which shows the mutual influences between court life and peasant culture in the 17th, 18th, and 19th-century Europe). Once exclusively a rural festivsl, today in Brazil it is largely a city festival during which people mimic peasant stereotypes and clichés and consume typical refreshments and dishes. As in Carnival, these festivities involve costume-wearing (in this case, peasant costumes), dancing, heavy drinking, and visual spectacles (fireworks display and folk dancing). As on Midsummer and St John's Day in Europe, bonfires are a central part of the festivities.
The four-day period before Lent leading up to Ash Wednesday is carnival time in Brazil.
Teresina/Senador Petrônio Portella Airport is located four kilometers (2.5 mi) from downtown Teresina. Opened in 1967, it has been administered by Infraero since 1975. There are no international flights to this airport.

The flag of Piaui was created on 24 July 1922. The blue canton and a star represents the state itself and the green and yellow bars represent Piauí's union with Brazil. In 2005 the words "13 DE MARÇO DE 1823" were added below the star to commemorate the date of the Battle of Jenipapo, an engagement in Brazil's war of independence.
