The manorial system of New France, known as the seigneurial system (), was the semi-feudal system of land tenure used in the North American French colonial empire. Both in nominal and legal terms, all French territorial claims in North America belonged to the French king. French monarchs did not impose feudal land tenure on New France, and the king's actual attachment to these lands was virtually non-existent. Instead, landlords were allotted land holdings known as manors and presided over the French colonial agricultural system in North America. Manorial land tenure was introduced to New France in 1628 by Cardinal Richelieu. Richelieu granted the newly formed Company of One Hundred Associates all lands between the Arctic Circle to the north, Florida to the south, Lake Superior in the west, and the Atlantic Ocean in the east. In exchange for this vast land grant and the exclusive trading rights tied to it, the Company was expected to bring two to three hundred settlers to New France in 1628, and a subsequent four thousand during the next fifteen years. To achieve this, the Company subinfeudated almost all of the land awarded to it by Cardinal Richelieu — that is, parceled it out into smaller units that were then run on a feudal-like basis and worked by habitants. The lands were arranged in long narrow strips called seigneuries or fiefs along the banks of the St. Lawrence River, its estuaries, and other key transit features. This physical layout of manorial property developed as a means of maximizing ease of transit, commerce, and communication by using natural waterways (most notably, the St. Lawrence river) and the relatively few roads. A desirable plot had to be directly bordering or in very close proximity to a river system, which plot-expansion was limited to one of two directions—left or right. Despite the official arrangement reached between Cardinal Richelieu and the Company of One Hundred Associates, levels of immigration to French colonies in North America remained extremely low. The resulting scarcity of labour had a profound effect on the system of land distribution and the habitant-seigneurial relationship that emerged in New France. King Louis XIV instituted a condition on the land, stating that it could be forfeited unless it was cleared within a certain period of time. This condition kept the land from being sold by the seigneur, leading instead to its being sub-granted to peasant farmers, the habitants.
