Hermann von Natzmer was the former Prussian officer who had been in charge of the arsenal of Berlin. Refusing to shoot insurgent forces who stormed the arsenal on June 14, 1848, Natzmer became a hero to insurgents across Germany.
The Wallachian Revolution of 1848 was a Romanian liberal and nationalist uprising in the Principality of Wallachia. Part of the Revolutions of 1848, and closely connected with the unsuccessful revolt in the Principality of Moldavia, it sought to overturn the administration imposed by Imperial Russian authorities under the Regulamentul Organic regime, and, through many of its leaders, demanded the abolition of boyar privilege.
