Colonial history of the United States Lower Louisiana. This vast tract was first settled at Mobile and Biloxi around 1700, and continued to grow when 7,000 French immigrants founded New Orleans in 1718. Settlement proceeded very slowly; New Orleans became an important port as the gateway to the Mississippi River, but there was little other economic development because the city lacked a prosperous hinterland. In 1763, Louisiana was ceded to Spain around New Orleans and west of the Mississippi River. In the 1780s, the western border of the newly independent United States stretched to the Mississippi River. The United States reached an agreement with Spain for
Livonia, Louisiana reportedly south of these on the water's edge. France ruled the Livonia area as part of Louisiana from 1699 to 1763, when the area was ceded to Spain. Spain controlled the area until 1800 when Napoleon took control of Louisiana for France. Some French Canadians migrated to Louisiana earlier, but the majority came between 1755 and 1764 after being expelled from Acadia. Some of the French culture remains in Livonia, as shown by the 2000 census that revealed 5.6% of the parish spoke French, Cajun French, or Louisiana Creole French. The land was sold to the United States in 1803
