A survey of Greek high school students has shown that very few have a good general knowledge of history and often confuse events and historical periods. The survey, carried out by a researcher at the Ionian University’s history faculty among 150 high school students, showed that many were not able to link developments in different historical periods. One-fifth of respondents did not even try to answer a question on what weapons they thought may have been used in various wars throughout history. Others replied that Molotov cocktails and nuclear weapons were used in World War I, or that rifles were used in the Peloponnesian War between Athens and Sparta in the 5th century BC. Only 27.8 percent were able to put a series of events in Greek history in the right order.
