The 9x19mm Parabellum, also known as the 9 mm Luger by the C.I.P. or 9 mm NATO by NATO, is a pistol cartridge introduced in 1902 by the German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) for their Luger pistol.[4] Its parent cartridge was the 7.65x22mm Parabellum, itself a descendant of the earlier 7.65x25mm Borchardt cartridge. The 9x19mm Parabellum is commonly used in pistols, submachine guns and carbines.
The name Parabellum is derived from the Latin: Si vis pacem, para bellum ("If you seek peace, prepare for war"), which was the motto and telegraphic address of DWM.
