The Derby of the eternal rivals (Greek: Ντέρμπι των αιωνίων αντιπάλων), also called Mother of all battles (Greek: Μητέρα των μαχών), is the name of the basketball local derby in Attica (Piraeus and Athens) between Olympiacos and Panathinaikos. The Greek powerhouses have won a combined ten EuroLeague titles since 1996, thus being among the most successful clubs in European basketball history. Panathinaikos basketball club has won seven EuroLeague titles and Olympiacos has won three EuroLeague titles. Their rivalry inside and outside the Greek borders is considered one of the most thrilling in the basketball world.[1][2][3][4][5]
The rivalry between the two top Greek clubs can be traced back to some social, cultural and regional differences. Panathinaikos comes from the center of Athens and was considered the classic representative of the old Athenian society and culture. On the other hand, Olympiacos comes from Piraeus and used to represent the middle class of merchants in the port of Piraeus and the world of the working class. However, this kind of clash was much more pronounced in the past, as the class differences between the fanbases have faded out and the social gap that once separated the two sides has closed over the years. Nowadays, both clubs boast fanbases that represent all the social classes.
Panathinaikos and Olympiacos are the two most successful basketball teams in Greece. The eternal enemies are the most traditional basketball powers as they have been fighting in the top level of the Greek basketball scene longer than any other team.
Their rivalry is highly credited, especially in the 1990s-2000s, when they met each other in several regular season and playoff series, and in some EuroLeague matches which marked their history.
