Trenck's Pandurs (, , Hungarian: Pandúr) were a light infantry unit of the Habsburg monarchy, raised by Baron Franz von der Trenck under a charter issued by Maria Theresa of Austria in 1741. The unit was largely composed of volunteers from the Kingdom of Slavonia and Slavonian Military Frontier, and named after security guards otherwise employed to maintain public order. The Pandurs were presented to the empress in May 1741—with the unit's military band—earning them a claim of pioneering martial music in Europe. The Pandurs did not use uniforms and had an overall oriental/Ottoman appearance. The original organization of the unit was retained until 1745, when it transformed into a regiment. Trenck was relieved of command in 1746 and imprisoned in Spielberg Castle, where he died in 1749. The unit ultimately transformed into the 53rd Infantry Regiment, headquartered in Zagreb, until it was disbanded in 1919. The regiment's commemorative medals bear Trenck's image wearing Pandur attire. The Pandurs took part in the War of the Austrian Succession, including the First and Second Silesian War. They contributed to the capture or destruction of Zobten am Berge, Strehlen, Klaus Castle, Linz, Deggendorf, Diessenstein Castle, Cham, Cosel fortress and Munich. During the Battle of Soor, the unit looted a Prussian war chest and the belongings of Frederick the Great. The Pandurs earned a reputation as brave, audacious, feared and ruthless soldiers, known for looting and pillaging. They were prone to disobedience, breaches of military discipline and stubbornness. The city of Waldmünchen, located near Cham, celebrates the Pandurs and Trenck as the city's saviors for sparing the city from destruction in 1742. The Pandurs' and Trenck's heritage is also preserved in the city of Požega, Croatia, where an eponymous living history troop and city music band exist. Etymology The term pandur made its way into military use via the Hungarian language—being used in Hungarian as a loanword, in turn originating from the Croatian term pudar, though the nasal in place of the "u" suggests a borrowing before Croatian innovated its own reflex for Proto-Slavic /ɔ̃/. "Pudar" is still applied to security guards protecting crops in vineyards and fields, and it was coined from the verb puditi (also spelled pudati) meaning to chase or scare away. The meaning of the Hungarian loanword was expanded to guards in general, including law enforcement officers. The word was likely ultimately derived from medieval Latin banderius or bannerius, meaning
