Invasions of people--many of the groups came as military and fought the Romans as invading forces.
Counterclaim--they were migration patterns as they were attempting to gain access to an empire with advanced trade and education. Migrating to the Roman Empire gave a person or group with extra resources.
Well I’m not going to write an entire essay for you, but here are some points that might help. I would encourage you to write about how you would join the war.
Consider that those who don’t join the war will be looked upon unfavourably by most, especially allies they swore to help. Essentially, you would be treated poorly at post-war negotiations.
Also consider the nationalist fervour present among the populous in most European states. People were rather excited for war in many cases, with many believing the war would be over by the Christmas of 1914. Not many knew the true horror of what would transpire during the war, and those who did didn’t make it known to the civilian population whose support they relied upon. Finally, bring up how Belgium declared neutrality but was still invaded by the German army.
In the case of Mexican History, it was Lazaro Cárdenas.
Seems the answer would be D.
Shinto and Buddhism hope that helps
