Vespers is a prayer ceremony in Catholic church and also associated penultimate ecclesiastical division of time, common in monasteries (prior to completa) and its name is derived from Greek ἑσπέρα and Latin vesper (both meaning 'evening'). The term was never associated with any form of revolt or ethnic cleansing in general, and is the name used in the common designation of the Sicilian uprising against the supporters of Charles I in Palermo, on the day of Easter in 1282 that quickly escalated in the general uprising in Sicily. This even became known as 'Sicilian Vespers' because the conspirators made the bells for Eastern Vespers their signal to begin action (it was much easier to use a city-wide signal rather to make their own). The name 'Asiatic Vespers', originally known as 'Ephesian Vespers' is an event related to the coordinated series of attacks against Romans in Asia Minor by supporters of Mithridates in 88 BCE, but the term itself has been first used only in 1890 by French archaeologist Theodore Reinach, by a direct association with aforementioned 'Sicilian Vespers'. It is possible that some others used the term to denote other bloody uprisings or massacres later, but this is definitely not an accepted usage of the term that is limited to the original event of 1282 (or 88 BCE).
