After the February Revolution, Bosch and Pyatakov were among the first Bolshevik emigres to return to Petrograd. She moved soon afterwards to Kyiv, where she was elected chairman of the party committee for the Southwestern region.[3] She then returned to what was then the Russian Republic, originally aiming at organizing an opposition to Lenin. After the April conference of the RSDLP, Bosch came to change her position, adhering to Lenin's ideas. Her reconciliation with Lenin cost her her marriage. She was elected chairman of a district (okrug) Party Committee and then of a provincial (oblast) Party Committee in the Southwestern Krai.[citation needed]
