I want to know the answer to the following question:
What is the Abyssinian crisis?
All the background I'm provided with is that "A series of international crises strained the League to its limits, the earliest being the invasion of Manchuria by Japan and the Abyssinian crisis of 1935/36 in which Italy invaded Abyssinia, one of the only free African nations at that time.". Is that enough to answer the question?
