This animated presentation from The Map as History visualizes the growth of the U.S. as it acquired North American territory, from the Louisiana Purchase up to the Civil War.

University of Iowa history professor Marshall Poe interviews Leslie Schwalm on her book Emancipation's Diaspora: Race and Reconstruction in the Upper Midwest. The book traces the migration of African Americans to Iowa, Wisconsin, and Minnesota during and after the Civil War and the harsh reception they received.

From the Civil War Traveler website:

"Late in the evening on Oct. 16, 1859, John Brown and a small band of insurgents entered Harpers Ferry (then Virginia), planning to ignite and arm a slave insurrection. This tour covers raid-related sites in the national park at Harpers Ferry (now West Virginia)."

From the Library of Congress website:

"In this interview from 1940, Mr. George Johnson of Mound Bayou, Mississippi, shares memories of slavery times, including his relationship with Jefferson Davis, President of the Confederacy."

From the National Constitution Center website:

"With the assassination of Abraham Lincoln, an old-fashioned southern Jacksonian Democrat of pronounced states' rights views became the seventeenth president of the United States. In a surprising turn of events, Andrew Johnson was charged with the reconstruction of the defeated South, including the extension of civil rights and suffrage to African American Southerners. It quickly became clear that the president supported the enactment of 'black codes' and would block efforts to force Southern states to guarantee full equality for African Americans, igniting a fierce battle with congressional Republicans. Acclaimed author David O. Stewart returns to the Constitution Center to discuss the impeachment trial of President Johnson, which became the central battle of the struggle over how to reunite a nation after four years of war."

From the Library of Congress website:

"What effect did the Emancipation Proclamation have on the Civil War? Did it have a broader effect on the slave trade throughout the Americas? In celebration of Law Day, these questions and many more were discussed by Congressman G.K. Butterfield, Congressman Jesse Jackson Jr., Dean Kurt Schmoke and Professor Emeritus Roger Wilkins, with PBS Newshour's congressional correspondent Kwame Holman moderating."

From the Lincoln Online Conference website:

"For a nation at war over slavery, President Lincoln's Emancipation Proclamation was inevitable. Its timing and content, however, were not without great struggle. The 'how' of the proclamation was just as critical as the 'when,' but it began a chain of events that changed not just our Constitution but the face of the nation. Lonnie Bunch, Founding Director of the Smithsonian's National Museum of African American History and Culture, will examine Lincoln's challenges to introduce a document that became a cornerstone event for communities of all races for generations to come."
