Trade helped empires gain money, troops, slaves, food and relations with other empires
The Olmec, Mayan, Incan, and Aztec civilizations are some of the greatest ancient civilizations in history, and yet we know very little about them compared to other parts of the world. The Olmecs are frequently forgotten entirely, and the rest are often lumped together or confused, but they were all completely distinct. In short, the Maya came first, and settled in modern-day Mexico. Next came the Olmecs, who also settled Mexico. They didn’t build any major cities, but they were widespread and prosperous. They were followed by the Inca in modern-day Peru, and finally the Aztecs, also in modern-day Mexico.
Hopefully this answers your question if it doesn’t and I just overlooked it lmk.
Through the many wars and peace congresses of the 18th century, European diplomacy strove to maintain a balance between five great powers: Britain, France, Austria, Russia, and Prussia. At the century’s end, however, the French Revolution, France’s efforts to export it, and the attempts of Napoleon I to conquer Europe first unbalanced and then overthrew the continent’s state system. After Napoleon’s defeat, the Congress of Vienna was convened in 1814–15 to set new boundaries, re-create the balance of power, and guard against future French hegemony. It also dealt with international problems internationally, taking up issues such as rivers, the slave trade, and the rules of diplomacy. The Final Act of Vienna of 1815, as amended at the Congress of Aix-la-Chapelle (Aachen) in 1818, established four classes of heads of diplomatic missions—precedence within each class being determined by the date of presentation of credentials—and a system for signing treaties in French alphabetical order by country name. Thus ended the battles over precedence. Unwritten rules also were established. At Vienna, for example, a distinction was made between great powers and “powers with limited interests.” Only great powers exchanged ambassadors. Until 1893 the United States had no ambassadors; like those of other lesser states, its envoys were only ministers.
