The Easter customs of Agrinio come to life through the Chalkounopolemos, a tradition that is revived every year on Good Friday. The tradition began during the Ottoman occupation, when Christians made the chalkounia in order to drive away those of other faiths who were obstructing the procession of the Epitaphios. After liberation, the Chalkounopolemos evolved into a game between the parishes of Agrinio, with two opposing groups, the “Vrachoriotes” and the “Souliotes,” competing in Stratos Square for dominance.

The tradition went through various phases, including bans and revivals. In the 1990s, the Giotopoulos, Tsironas, and Koutsoukis families undertook the revival of the custom, ensuring the safety of the chalkounia, which are carefully made to avoid accidents. The Chalkounopolemos today remains an integral part of the Easter customs in Agrinio, continuing to excite locals and visitors with its spectacular performance and the intense emotional atmosphere it creates.
