Both Andrew Carnegie Mellon and Henry Clay Frick were industrialists and business partners. Carnegie produced steel and Frick manufactured coke (necessary to produce steel). Frick eventually became chairman of Carnegie's company, but Carnegie made several attempts to force him to renounce to his position and disregarded him, and his opinions, on numerous occasions. This is, therefore, an example of the tensions that the industrialization of the U.S. entailed (there were companies that merged with, or sometimes bought, other companies; companies that used black workers and convicts as labor; companies whose workers went on strike; and hostility towards the wealthy industrialists as well as between them).
Jerusalem was chosen by King David as their capital city, it is the most religious place in the world. Jerusalem was also the place were the crucifixion was at (If you didn't know).
