The majority of Italian immigrants in New Orleans were from Sicily and started to arrive in large numbers in the 1880s to escape a homeland that had fallen into a corrupt, dangerous, and unlawful state.
They arrived in a city where previous Italian immigrants had established a decent-sized community, dating back to the French era. In fact, the Italian-born Henri de Tonti, as part of a French expedition, explored Louisiana even before New Orleans existed and later became a leader in the fledgling colony. A street named after Tonti is still here.
