The confluence of the Hudson and Mohawk rivers offers a sweeping view of American history, from Mahican Indians and the Revolutionary era to industrialization, canals, education, labor, and baseball. The valley became a major center of the American Industrial Revolution because its waterways and falls powered machinery and moved raw materials and finished goods, while places such as South Troy, Watervliet, Cohoes, Lansingburgh, and downtown Troy developed industries including iron, steel, textiles, bells, brushes, shirts, collars, stoves, engineering instruments, and cannon manufacture. The Erie Canal and Champlain Canal transformed the region into a gateway linking Albany, Cohoes, Waterford, and the West, helping make New York City the major U.S. port by 1825. The area also figured prominently in the Revolution, with Van Schaick Mansion serving as headquarters where plans for the Battle of Saratoga were made, and breastworks on Peebles Island built to help protect Continental troops awaiting Burgoyne. The view encompasses institutions and people of lasting influence, including Rensselaer Polytechnic Institute, Emma Willard School, Russell Sage and Margaret Olivia Slocum Sage, Deborah Powers, Kate Mullaney, Harriet Tubman, Samuel Wilson, and the Troy Haymakers, whose legacy was linked to the later New York Giants.
