What were the tours that traveled to different regions to encourage settlement in North Dakota called?

The term "Immigrant Excursions Trains" is correct because these tours were specifically designed to attract new settlers to North Dakota by showcasing the land and opportunities available for farming and living in the region. During the late 19th and early 20th centuries, railroads played a crucial role in promoting settlement in the Midwest, particularly in North Dakota. These excursion trains often featured reduced fares and included stops at strategic locations to highlight the potential of the area, thus encouraging migration and settlement.

The name reflects both the nature of the trips—train journeys for potential immigrants—and their purpose, as they targeted individuals and families looking for new opportunities in the frontier. The promotional efforts were essential in supporting North Dakota's growth during a time when the state was still being developed after its admission to the Union. The other terms might not capture the essence and specific context of these organized tours aimed at attracting immigrants.
