Concepción () is a department of Paraguay. The capital is the city of Concepción. History Throughout history, this department has suffered a great amount of population instability, especially in the times of the colony, due to the advance of the Brazilian "bandeirantes" through the east and the attacks of the Mbayá – Guaicurú natives of Chaco, which, by then, were the lords of that region. During the later years of the colony, it was organized a great campaign to re-conquest the invaded territories with the intention of defending by populating the region and also with the important task of the Jesuit that founded the city of Belén, of creating a Mission with the Mbayá natives, in the year 1760. During the governments of Francia and López, the populating process got stronger and the north area of Paraguay became a territory dedicated to cattle. Francia ordered the construction of the penal colony of Tevego in 1813 in the Concepción department. Once the Paraguayan War was over, Concepción united with Amambay, constituting a great territory for forestall and yerba plantations. In the Twentieth Century, Concepción was proclaimed to be the second most important city of the country and it became an active commercial center. Because of its bind with Mato Grosso it experienced important development during that time. In the year 1906, with the first plan to arrange the national territory, it was proclaimed the first department. Its limits were established with the decree 426 of 1973, as we know them nowadays.
