彼得格勒苏维埃
The Executive Committee of the Petrograd Soviet, commonly known as the Ispolkom (, literally "executive committee") was a self-appointed executive committee of the Petrograd Soviet. As an antagonist of the Russian Provisional Government, after the 1917 February Revolution in Russia, Ispolkom became a second center of power. It was dissolved during the Bolshevik October Revolution later that year. Ispolkom is known for the controversial "Order No 1" (and 3) which stipulated that all military units should form committees like the Petrograd Soviet and that the military from every "political perspective" should not contradict to Ispolkom. The socialists at the Petrograd Soviet feared that officers were the most likely counter revolutionary elements and the intention of the Order was to limit their power, but these orders rendered the officers powerless at the Russian front lines of World War I, which had led to confusion, disastrous military discipline, and desertions.
