Negotiating international peace treaties
The correct answer is either manifest destiny or the civil war
Because of the civil war and the expenses of maintaining a navy that could blockade Confederate ports, the Navy was constantly losing power and ships and after the war ended most of the 700 initial ships were completely out of service. As manifest destiny and reconstruction began spreading, the government did not focus on rebuilding its navy and a large part of the navy that remained had to focus on things like helping merchants or doing civilian runs in order to be sustained.
European nations give away land to people willing to settle and work in their colonies, because they have to pay the people to live there, as many of their civilians didn't want to go, for there were no profit in going "Why would we go to an unkonwn place for no profit". The land allowed companies to send settlers there, as people went there to farm or get rich quickly
hope this helps
