The north had already begun industrializing for a while, but in the 1870's and beyond, things ramped up quite a bit. Factories for clothes, shoes, farming equipment, packaged foods, and etc. became more popular. You also had coal mines, railroads, and steel mills. This showed the country was moving in the direction of mass production, and moving away from agricultural ways of living. This also meant child labor, which led to many child labor laws in the later years. This also meant many moved out of farming communities, and into larger, noisy, and crowded cities. Many immigrated to the US to take advantage of that, which led to some tension between communities.
