The Greek army entered Servia on 10 October 1912, during the First Balkan War, after its victory against the Ottoman army in the Battle of Sarantaporo. On the same day, 117 prominent citizens of Servia were gathered and executed by the Ottomans who were leaving the city, 75 to 90 severed human heads were lined up on either side of one of its streets. From then on the main road of the town leading to the Town Hall is called "117 Εθνομαρτύρων" ("117 ethnomartyron"), i.e. "Of the 117 National martyrs", in remembrance of this dreadful event. Servia was granted to the Kingdom of Greece by the Treaty of Bucharest in 1913.
