There are special historical links between Chaidari and the 1821 Revolution, since critical battles (6 and 8 August 1826) took place in Chaidari, while a minor battle happened in Daphni (21 March 1827), a few weeks before the sore Greek defeat at Analatos. G. Karaiskakis and C. Faviere were the protagonists of the Chaidari and Daphni battles, as leaders of the Greek forces and a Philhellene battalion, which attempted to relieve the Akropolis from the siege of general Kutahiye. The Chaidari battles took place in Elaionas, in the area of the Palataki tower, then an estate known as Acherdari (hence Chaidari), after its owner Chaidar Pasha.
The Greeks fortified in the neighbouring hills, which were suitable for their guerilla tactics. A commemorative stela today reminds of the events. The early 19th century Chaidari had very few pastoralist residents. It was
marked by G. Flaubert’s passage, the sacking of Homer Vrioni in 1821 and the Greek guerilla camps during the Revolution.
