Desiring ownership of good agricultural land above all else, and finding after 1835 that the best and cheapest was to be found along the advancing frontier west of a north-and-south line drawn through Chicago, the men from Norway, Sweden, and Denmark followed their distant cousins of New England and the Middle States in the great trek into the Any-Man’s-Land of the fertile upper Mississippi Valley.[158] For more than two decades after the Civil War, tho slavery no longer existed in the South, that region was still in the depression and uncertainty of the post-bellum industrial disorganization, and hence unattractive to immigrants of any class. So the tide continued to run high in the Northwest and spread wider and wider because of the traditions of two generations, and because of the attracting power of the Scandinavian mass already comfortably and solidly settled there.

The first States of the Northwest into which the Norwegians and Swedes penetrated, as has been described above, were Illinois and Wisconsin; and in the censuses of 1850 and 1860 Wisconsin held first place in the number of these aliens, showing an increase from 8,885 to 23,265.[159] In 1850, Iowa, in the “far west,” ranked fourth, with 611. Minnesota, which then stretched away to the Rocky Mountains, had 4 Swedes, 7 Norwegians, and 1 Dane.[160] By 1860 Iowa was passed by Minnesota which then had 11,773, and thenceforward the Scandinavians were to keep close step with the westward march of the frontier. In 1870 Minnesota took first place, with 58,837, a position which the State has continued to hold. In 1890 she had within her borders 236,670 foreign-born Northmen, and enough of the second generation to make her Scandinavian population 466,365, or about one-fifth that of Denmark or Norway. The order of Minnesota, Wisconsin, Illinois, and Iowa held good for 1870 and 1880, but Wisconsin and Illinois changed places in the reports of 1890 and 1900. The Dakotas, as one Territory, received their first Norse settler in 1858, but when the census of 1880 was taken there were 17,869, and in 1890, when the Territory was divided into two States, the Scandinavian contingent was more than 65,000 strong.[161] Nebraska illustrated in a similar manner the widening overflow of the steady stream out of the European North; her population of Scandinavian birth which numbered only 3,987 in 1870, grew by direct entry of immigrants, and by the secondary movement of early immigrants out of the middle Northwest, to 16,685 in 1880, and to 40,107 of foreign-born in 1900. According to this last census, Nebraska counted 38,914 native persons of foreign-born Scandinavian parents, showing that the second generation did not fall much behind the first in the habit of frontier-seeking.[162]

In the rush of gold-seekers into California after 1848 were many Danes and Swedes, who gave that State in 1860 fifth rank as to the number of Scandinavians; by 1890 these numbered about 42,000, of whom the greater part were of the two nationalities just named. Another frontier region which gained from the Danish immigration between 1850 and 1860 was the Territory of Utah, for the Mormon missionaries seem to have been particularly successful in Denmark, and nearly every convert became an immigrant. Quite in advance of their invasion of Dakota, more than 2,000 Danes had settled in the Mormon Territory, and ten years later Utah counted nearly twice as many Scandinavians as Nebraska, seven-tenths being Danes.

The increasing density of this Scandinavian population in certain localities,—what might be called its vertical distribution—is strikingly illustrated in both urban and rural communities. Chicago had barely emerged from the Fort Dearborn stage when the first Scandinavians walked its streets. Yet within two generations there were found inside of her wide-stretching borders more than 100,000 Swedes, Norwegians, and Danes of foreign birth, and enough of the second generation to give her more than 190,000, so that the city at the head of Lake Michigan was next after Copenhagen, Stockholm, and Christiania,—the largest Scandinavian city in the world.[163] By a similar calculation, Minneapolis would rank sixth or seventh.

Rockford, Illinois, received the first of its signally prosperous Swedish colony about 1853; by 1865 the city had 2,000 Swedes.[164] The census of 1910 credits Rockford with 10,000 foreign born Swedes, and a total of Swedish parentage reaching close to 19,000. One of the west-central counties of Minnesota, Otter Tail, counted (1900) more than half of its 45,000 population of pure Scandinavian blood of the first and second generation of immigrants. Polk county, newer and farther north in the same State, reveals almost sixty per-cent of the same sort of population in a total of 35,000. For some of the still newer and more sparsely settled counties even larger percentages might be obtained.

A closer analysis of the tables of population reveals some further facts as to the distribution of the different nationalities. The Swedes are the most numerous in Minnesota, Illinois, Iowa, Michigan, Nebraska, and Kansas; the Norwegians predominate in Wisconsin, North Dakota, and South Dakota, and nearly equal the Swedes in Minnesota where each passes 200,000. The Danes are strongest—they can hardly be called a very important factor in any State—in Iowa, Minnesota, Wisconsin, Illinois, and Nebraska; in each State they have more than 25,000. Another feature of this varying density of the three groups has to do with the cities. Chicago, Rockford, Minneapolis, St. Paul, and Duluth account for a large proportion of the Swedes of Illinois and Minnesota, and represent the later rather than the earlier stages of distribution. Outside of the cities mentioned, the Norwegians in Minnesota outnumber the Swedes by some 52,000. In North Dakota, the Norwegians are 72% of the foreign-born Scandinavian population, in South Dakota, 56%, and in Wisconsin, 60%, while in Illinois the Swedes are about 70%, and in Michigan and Nebraska, 63% and 59% respectively. The Danes reach their highest percentages of the Scandinavian foreign-born in Utah, 50%, in Nebraska, 34%, and in Iowa, 23%. Large numbers of the later immigrants, especially of the skilled Swedish laborers, have found occupation in New York and Brooklyn, Boston and Worcester, Hartford and Providence. These have raised the proportion of the Swedes in the United States living in cities of more than 25,000, to 36%, while only 28% of the Danes, and 19% of the Norwegians were similarly located in 1900.[165]

Climate, particularly the mean temperature, has also played considerable part in the choice by the immigrants from Northern Europe of the sites for their new homes, though it is an open question whether they would not have been established where they were and when they were even if the climate were different. Certain it is that the few Icelandic settlements are situated in the extreme northern part of Minnesota and North Dakota, and in Southern Manitoba.[166] South of them come, in order, the zones of densest Norwegian population, 49° to 42°, of the Swedish, 48° to 40°, and of Danish, 44° to 38°. The three nationalities thus occupy relatively the same latitudinal position in America as in their homes in the Old North.[167]

Summarizing the matter of location, the great bulk of the Scandinavian immigrants went into the Northwest, 78% of them during the first fifty years of the movement, and about 70% of the total. Out of the immigration of the different nationalities, 81% of the Norwegians are in the Northwest, 60% of the Danes, and 59% of the Swedes, the percentage of the last being brought down, in comparison with the Norwegians, by the fact that nearly 100,000 Swedes are found in Massachusetts, New York, and Pennsylvania.[168]

The Civil War occurred before the numbers and expansion of the Norse element of the country’s population had much passed a promising beginning; the 75,000 present in 1860 could not be expected to play any large and leading rôle. Yet the one dramatic and heroic chapter in the whole story of the progress of the Scandinavians in America is that dealing with their part in that great struggle, in which many hundreds of them gave their strength and their lives for the unity and safety of their adopted country no less bravely and no less cheerfully than did the native-born American. The men from Thelemark and Smaaland and the sons of Massachusetts and Michigan were inspired by the same fine and pure motives; they hated slavery and loved the flag under whose folds they realized their hopes and dreams.[169] By temperament, by religion, by education, by tradition, men of Norse parentage were fitted to participate in upholding a cause so essentially right and high.
