The document discusses the internationalization of the Spanish Civil War (1936-1939) through three main points:
1) It defines internationalization as the explicit decision to involve international actors in a domestic conflict.
2) It explains various factors that can lead to internationalization, including domestic interests of local parties seeking military/political support, and international factors like opportunism and interventionism.
3) It discusses the international context of the 1930s in Europe, with the rising threats posed by fascist regimes in Germany and Italy seeking territorial expansion, countered by France and Britain's support for the post-WW1 status quo.
