Proschema (plural "proschemata") is the equivalent Greek term, first popularized by Thucydides in his "History of the Peloponnesian War". The proschemata are the stated reasons for waging war, which may or may not be the same as the real reasons, which Thucydides called prophasis (). Thucydides argued that the three primary real reasons for waging war are reasonable fear, honor, and interest, while the stated reasons involve appeals to nationalism or fearmongering (as opposed to descriptions of reasonable, empirical causes for fear).
