Answer:
Moving west on the Oregon Trail
Explanation:
In the early 19th century the rough outlines of the Oregon Trail were set by Frontier explorers and fur trappers. But it wasn´t until 1843 that the first wagon train of about 1000 settlers (mostly families), known as the Great Migration left for pioneering the west. Word got around and from then on the Oregon Trail received up to 50.000 people every year. This explains the historical importance of the Trail for many migrants who carried their belongings in their wagons.
