Saitopolemos is a customary celebration that take place in the Greek city of Messini during Easter.
 According to legend, its roots can be traced back to the Greek War of Independence in the 1820s, and especially to a battle the Greeks fought against the army of the Egyptian Sultan Ibrahim Pasha.
 However, this explanation is disputed.
 The 19th century Greek Romantic tradition used to place the nativity of the majority of Greek customs in the period of Turkish occupation (1453-1821).
 The biggest argument against the traditional view is the fact that the celebration takes place during Easter week, whereas most historians agree that the events the traditional songs refer to did not occur during that time of year.
