[3] An active centre in salt commerce, Esqueira was the seat of its jurisdiction (over thirty 31 towns and 10 municipalities).

[3] During the reign of John III there was a reorganization of the territorial divisions of the kingdom, resulting in the establishment of new comarcas, including Esgueira on 20 December 1533.

[3] With the elevation of Aveiro to city, the lands were converted into crown lands, after the Dukes implicated in the attempted assassination of Joseph I of Portugal were executed: the privileges of the Dukes were removed, and transferred by 6 November 1836 decree, extinguishing the municipality and annexxing Esgueira (as a simple parish) to the municipality of Aveiro.

[3] The civil parish consists of various localities, including: Senhor do Álamo/Cruzeiro, Bairro do Vouga, Agras do Norte, Cabo Luís, Bela Vista, Taboeira, Quinta do Simão, Mataduços and Paço.

Esgueira has an annual population of approximately 3050 students, distributed among five kindergarten/primary schools (including EB1/JI Taboeira, EB1/JI Esgueira, EB1/JI Alumieira, EB1/JI Quinta do Simão and Cabo Luís/Bela Vista), one middle-school (Escola Básica 2º/3º Ciclos Aires Barbosa), and a secondary school (Escola Secundária Jaime Magalhães Lima).
