Diplomacy and International Relations
What to know
Diplomacy questions test treaties, doctrines, and the pressure of domestic politics. Know the colonial wars and the 1763 Treaty of Paris, the Proclamation of 1763, the Revolution's French alliance (1778), and the 1783 Treaty of Paris. In the early republic, know Washington's Neutrality Proclamation and Farewell Address, Jay Treaty, Pinckney Treaty, XYZ Affair, Louisiana Purchase, and the War of 1812. The Monroe Doctrine (1823) warned European powers against new colonization in the Americas. Understand Manifest Destiny, Texas annexation, the Oregon dispute, the Mexican-American War, and the Treaty of Guadalupe Hidalgo. Civil War diplomacy included the Trent Affair and Confederate "King Cotton" hopes.
Traps
The Monroe Doctrine was a presidential statement, not a treaty. Washington's Farewell Address advised neutrality and warned against permanent alliances; it did not forbid all trade. The 1783 treaty set boundaries and fishing rights but left tensions. The Mexican Cession came from Guadalupe Hidalgo; the Gadsden Purchase came later. Avoid confusing the 1763 and 1783 Treaties of Paris.
Worked example
A question asks which agreement secured the Louisiana Purchase. Answer: the 1803 treaty with France, authorized by Jefferson despite strict-constructionist doubts. Rule of thumb: for each diplomatic event, name the treaty or doctrine, the year, and the domestic interest it served.
