Final answer:
Inter regional contact and conflict historically led to trade agreements, resolution of disputes, and cultural exchanges, as seen through peaceful acquisitions like tribute systems and intermarriage, as well as expansionist goals exemplified by US foreign policy and historical figures like Zheng He.
Step-by-step explanation:
Inter regional contact and conflict between states and empires historically resulted in establishment of trade agreements, resolution of territorial disputes, and the promotion of cultural exchanges. For example, the methods used to acquire territory peacefully included intermarriage and becoming tribute bearers to more powerful empires.
Meanwhile, figures like Zheng He aimed to explore and map regions like the Indian Ocean, establish trade, and incorporate areas into China's tribute system. As empires expanded, rail and telegraph played crucial roles in spreading influence, enhancing internal development, and facilitating trade. The spread of American influence, internal development promotion, and trade facilitation were all consequential outcomes of technological advancements.
Furthermore, in the context of Africa, the Arab invasion and the Bantu migration united the continent through culture, language, and religion. Trade played a pivotal role in uniting different regions, but territorial conflicts were handled differently compared to other parts of the world, being more centered on subjugation and forming alliances rather than land conquests.
