HistoryThe area was originally part of the Seigneurial system of New France, la Seignorie Rivière-du-Loup. This seignory was formed in 1665 by Intendant Jean Talon and granted in 1672 to Charles Dugey Rozoy-de-Mannereuil, officer in the Carignan-Salières Regiment, Carignan Regiment. The seignory was thereafter also known as Rivière-Mannereuil for some time. In 1714, a mission was formed by the Récollets who dedicated it to the patronage of Anthony of Padua. In 1722, the Ursulines owned the seignory and attempted to change the name to Saint-Antoine-de-la-Rivière-Saint-Jean but the settlement became known as Rivière-du-Loup or Rivière-du-Loup-en-Haut after the seignory or local river. In 1816, its post office opened. In 1845, the Parish Municipality of Rivière-du-Loup-en-Haut was formed, and abolished two years later in 1847. It was reestablished in 1855 as Saint-Antoine-de-la-Rivière-du-Loup, named after the parish patron and the seignory. In 1878, the main settlement separated from the parish municipality and formed the Village Municipality of Rivière-du-Loup. Just one year later it was renamed to Louiseville in order to avoid confusion with another town called Rivière-du-Loup in the Bas-Saint-Laurent region. The new name was a tribute to Princess Louise, Duchess of Argyll, Princess Louise, viceregal consort of Canada, the third daughter of Queen Victoria, who had planned to visit the Mauricie that same year. On January 1, 1989, the parish and village municipalities merged again and became the Town of Louiseville.
