<span>The Berlin Conference set down rules for dividing up Africa. This meant that the European colonizers established national borders that grouped certain African ethnic groups together. This meant that despite ethnic groups being historical enemies, they were now being forced to live within the same boundaries.
Ex: German & Belgian colonial governments aggravated the historically tense relations between the Hutu and Tutsi ethnic groups in present-day Rwanda and Burundi. The ethnic violence between these two groups resulted in a war that led to the deaths of hundreds of thousands of people (as we saw in the movie Hotel Rwanda).</span>
Well an obvious answer would be slavery, depending on how late you're talking. After slavery ended, the country began what is known as the "industrial revolution". 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.
Hope that helps!
