It is made up of 102 municipalities and its most populous cities are Maceió, Arapiraca, Palmeira dos Índios, Rio Largo, Penedo, União dos Palmares, São Miguel dos Campos, Santana do Ipanema, Delmiro Gouveia, Coruripe, Marechal Deodoro, and Campo Alegre.
Next to last Brazilian state in area (larger only than Sergipe) and 16th in population, it is one of the greatest producers of sugarcane and coconuts in the country and has an economy based on cattle raising.
Land of the sururu (or Charru Mussel), lagoon shellfish which serves as food for the coastal population, and of coconut water, Alagoas also possesses some of the country's richest folklore.
Initially, the Alagoano territory constituted the southern part of the Captaincy of Pernambuco and only gained its autonomy in 1817. It's occupation pushed the expansion of the captaincy's sugarcane farming, which required new areas of cultivation, southward. Thus arose Porto Calvo, Alagoas (now Marechal Deodoro) and Penedo, nuclei which guided the colonization, economic, and social life of the region for a long time.
The Dutch invasion in Pernambuco was extended to Alagoas in 1631. The invaders were expelled in 1645, after intense fighting in Porto Calvo, leaving the economy totally disorganized.
The escape of African slaves during the Dutch invasion created a serious labour shortage problem on the sugar plantations. Grouped in villages called quilombos, the Africans were only completely dominated at the end of the 17th century with the destruction of the most important quilombo, Palmares.
During the empire, the separatist and republican movement the Confederation of the Equator (1824) received the support of noteworthy Alagoano figures. Throughout the 1840s, political life was marked by the conflict between the lisos, conservatives, and the cabeludos, liberals.
At the beginning of the 20th century, the Alagoano hinterland lived through the pioneering experience of Delmiro Gouveia, a Pernambucano entrepeneur who installed the Estrela thread factory, which came to produce 200 spools daily. Delmiro Gouveia was killed in October of 1917 in circumstances still unclarified, after being pressured, according to rumor, to sell his factory to competing foreign firms. After his death, his machines would be destroyed and thrown into Paulo Afonso Falls.
Nicknamed the Land of the Marshals (Terra dos Marechais), for being the birthplace of Deodoro da Fonseca and Floriano Peixoto, Alagoas gave the country numerous illustrious Brazilians among whom are the anthropologist Arthur Ramos, the maestro Hekel Tavares, the philologist Aurélio Buarque de Holanda, the poet Jorge de Lima, the jurists Pontes de Miranda and Marcos Bernardes de Mello, besides the writers Lêdo Ivo and Graciliano Ramos.
