Hoping for 1916 myself. I don't think they'll make it as easy as causes and consequences, maybe more general such as ''Threat of violence from 1913 so on. Apprentice boys and Coleraine. WW2 North and South. Fianna Fail/ De Valera foreign policy.
Johnson and Vietname/ Foreigh Policy 1945-89 OR Foreign Policy 45-69 Or Foreign Policy 73-89.
Johnson and Truman
These are my preps anyway.
