Unit 7 Overview: Global Conflict

The one thing you need to know about this unit:
Global conflict changed the status quo through shifts in power. 
Industrialization = Nationalism = More challenges to dominant nations = Imperialism = Interregional conflicts 🔫

Contextualizing the Unit 💥

The 1900s featured a heavily industrialized world where even nations like Japan and Russia have begun to catch up to dominant economies like western Europe and the U.S. The Second Industrial Revolution also gave birth to new technological, transportation and communication advances such as railroad systems, telegraphs, and machines - all of which made life more convenient for everyone!
However, imperialism in Asia (e.g. French in Indochina, British in India) and Africa (the infamous Scramble for Africa) gave rise to intensified conflicts as they became more lethal and prevalent as new weapons emerged: flamethrowers, machine guns, artillery, tanks, fighter planes, the list goes on. These deadly contraptions allowed powerful nations to wage wars against each other to gain more land and influence over local regions. These wars were fought by different people - Indians, Africans, Europeans, Asians, and even Americans - in different theaters across the globe.
As more people became aware of the world beyond them, they started to challenge the social order as new forms of government often came hand in hand with the emergence of political and economic ideologies (e.g. communist regimes, fascist dictatorships, parliamentary republics, etc.).
What exactly happened BEFORE and AFTER each global conflict in terms of politics, society, and economy? Time to find out. 🕘
