The brigade traces its history to the 50th Infantry Regiment (Greek: 50ό Σύνταγμα Πεζικού, 50 ΣΠ), which was founded in 1919 in Adrianople (now Edirne in Turkey).

[1] The regiment fought in the Greco-Italian War in the Albanian front until the capitulation of the Greek Army following the German invasion of Greece in April 1941.

[1] After liberation, the regiment was reformed, initially for a short period as the 32nd Brigade (32η Ταξιαρχία), and stationed at Eleftheroupoli.

[1] The brigade's emblem features a purple triangular shield upon which is depicted a golden sphinx wielding a poleaxe.

The whole is edged in white, with an inscription above with the unit's motto, Αρχή του νικάν το θαρρείν ("Courage is the foundation of victory"), a quote from Plutarch (Life of Themistocles, 8.2) referring to the Battle of Artemisium in 480 BC.
