The Région Nouvelle Montréal is a major urban area that has been continously settled since the 1600s, however it has only been known as Nouvelle Montréal since the french community took the area from Rupertland in 1814. It is commonly defined as the area inside of the Autoroute de Notre Baie 1 (AB1). The area is anchored by the cosmolpolitan city of Nouvelle Montréal Sud. It has been the anchor of the Vue Baie province and Delongo's french community since the 1800s. Other major cities within its limits include Nouvelle Montréal Nord, Nouvelle Quebéc, Nouvelle Paris, Reigneville, St. Pierre, Veil, Mouston, Napeon, Bludonc, and others. Over 8.5 million people live in the area, accounting for almost two thirds of Vue Baie's population.
The region has grown into a pillar of French culture, almost 85% of the region's population speak French, which only 25% speak English, and only 18% speak a language other than English or French.
Entirely situated on the Baie Pétrolier (Oilman Bay) and centred on the Nouvelle Seine river, water has become intertwined with the region's culture and taste. It has been illegal to pollute in the sacred waters of the bay and the Nouvelle Seine since the 1840s, making the water some of the cleanest for any city in the world.
The majority of the region's population comes from the communes that surrond Nouvelle Montréal Sud. These are small to medium sized french towns, with few exceptions. Some have developed into larger villes, such as in the cases of Nouvelle Paris and Nouvelle Québec. All of the region's development has been limited due to laws inacted before the Great Blix Depression that wanted to keep the region's european flair.
In the 2000s, the region began opening up to carefully and smartly integrated new infrastructure and buildings. Controversially, the green belt surronding the wall of Nouvelle Montréal Sud has remained in place.
