The arrival in 1620 of the Mayflower and Puritan migration occupy the first pages of the history of colonial America. Less known is the exodus from New England, a century and a half later, of their Yankee descendants. Yankees engaged in whaling and the China Trade, and settled in Canada, the American South, and Hawaii. Between 1786 and 1850, some 800,000 Yankees left their exhausted New England farms and villages for New York State, the Northwest Territory and all the way to the West Coast. With missionary zeal the Yankees planted their institutions, culture and values deep into the rich soil of the Western frontier. They built orderly farming communities and towns, complete with church, library, school and university. Yankee values of self-labor, temperance, moral rectitude, respect for the law, democratic town government, and enterprise helped form the American character. New England was the hotbed of reform movements. Yankee-inspired religious movements spread across the nation and beyond. The Anti-Slavery and the Anti-Imperialism movements started in New England. Susan B. Anthony campaigned for women’s suffrage, Clara Barton founded the American Red Cross, Dorothea Dix established asylums for the mentally ill, and May Lyon was a pioneer in women’s education. Yankees spread the Industrial Revolution across America, using waterpower and then stream power. Opposing slavery and advocating education for all children, the Yankee pioneers clashed with Southerners moving north. In Kansas the dispute between Yankee and Southerner erupted into armed conflict. In time the Yankee enclaves in Detroit, Chicago, Cleveland, Minneapolis, and San Francisco fused with others to form the White Anglo-Saxon Protestant elite (WASPs), to dominate American commerce, industry, academia and politics. By the close of the nineteenth century, industry began to leave New England. Yankees felt threatened by the rising political power of immigrants. In an effort to keep the nation predominantly white and Protestant, prominent Yankees sought to restrict immigration from Asia, and from eastern and southern Europe, and impose quotas on American-Catholics and Jews seeking admission to elite universities and clubs. Despite barriers, the American-born children of the immigrants benefited from their education in public schools and colleges, entered the American mainstream, and steadily eroded the authority of the Protestant elite. The Immigration and Nationality Act of 1965 opened the United States to immigrants from Asia, Africa and South America. The great mix of races, religions, ethnicity and individual styles is forming a pluralistic America with equally shared rights and opportunities.

Northeast Pennsylvania's Wyoming Valley was truly a dark and bloody ground, the site of murders, massacres, and pitched battles. The valley's turbulent history was the product of a bitter contest over property and power known as the Wyoming controversy. This dispute, which raged between the mid-eighteenth and early-nineteenth centuries, intersected with conflicts between whites and native peoples over land, a jurisdictional contest between Pennsylvania and Connecticut, violent contention over property among settlers and land speculators, and the social tumult of the American Revolution. In its later stages, the controversy pitted Pennsylvania and its settlers and speculators against "Wild Yankees"—frontier insurgents from New England who contested the state's authority and soil rights.In Wild Yankees, Paul B. Moyer argues that a struggle for personal independence waged by thousands of ordinary settlers lay at the root of conflict in northeast Pennsylvania and across the revolutionary-era frontier. The concept and pursuit of independence was not limited to actual war or high politics; it also resonated with ordinary people, such as the Wild Yankees, who pursued their own struggles for autonomy. This battle for independence drew settlers into contention with native peoples, wealthy speculators, governments, and each other over land, the shape of America's postindependence social order, and the meaning of the Revolution. With vivid descriptions of the various levels of this conflict, Moyer shows that the Wyoming controversy illuminates settlement, the daily lives of settlers, and agrarian unrest along the early American frontier.
