Origins of the village
Local folklore suggests that the village was first settled in the year 1330 by Christian settlers from the Mat River region of Albania. The village was originally named Rakovo in Slavic. This word comes from Rakoits and means fresh water crayfish, which were plentiful in the nearby streams. The village was named Krateron in 1928 after the Second Balkan War of 1913 when the region became part of Greece according to the Treaty of Bucharest (1913). Many residents migrated from Kratero in the 1950s to start new lives in the United States, Canada and Australia.
Kratero at the time of the Ilinden Uprising (1903)
The village has experienced a turbulent history as a result of its location and the strong patriarchist and Greek national identity of the population  The village was burnt down three times, once in 1903 by the Ottoman Turkish Army, in 1907 by Bulgarian Bands, and in 1947 during the Greek Civil War.
The village of Kratero was heavily affected by the events of the Ilinden Uprising of 1903 due to the villages remote location in the Monastir Vilayet of the Ottoman Empire. The villages of the Monastir Vilayet were subject to intimidation by Bulgarian Bands who attempted by violent means to bring the Greek Patriarchist villages to the Bulgarian Exarchate. When the Greeks of Kratero cataegorically refused to support the Bulgarians, they were threatened with the burning of the village. The Greek priest, Papa Dimitrios and two notables, K. Traianou and Y. Konstantinou were murdered, and five more members of the community were beaten. Later, a Bulgarian armed band again raided Kratero murdering the Greek Priest Mitanidis, the village President Stavros Maligeorgos, and Vice President Yiorgos Boikovitis. In August 1903 Ottoman troops attacked the village in their attempts to deal with the Ilinden insurrection, burning and destroying 100 out of 120 houses.
