Left Communists opposed which elements of Bolshevik policy in 1918-1919?

• A. They criticized the Treaty of Brest-Litovsk and some NEP measures
• B. They supported the Treaty of Brest-Litovsk without reservations
• C. They advocated immediate capitalist reforms
• D. They favored dissolution of the party

Answer: (D)

The main idea here is understanding where the Left Communists stood on Bolshevik control and policy in 1918–1919. They believed the party had become too insulated from the working class and from the actual power of the soviets. They argued for a move toward broader democracy within the workers’ movement, and in some formulations they even pressed for dissolving the party’s monopoly on power so that decision-making could be exercised more directly through the soviets and mass organizations rather than through a centralized party leadership.

This attitude helps explain why the option describing dissolution of the party is the best fit for what they opposed. It captures their push against a tightly centralized party structure and their desire to re-align power with the broader worker and socialist-democratic forces. They also criticized specific Bolshevik measures like the Brest-Litovsk treaty and certain NEP steps, but their distinctive stance was that the party should not hold exclusive authority and should be dissolved into or replaced by mass democratic structures.

In short, their call to dissolve the party signals their broader critique of Bolshevik centralization and their belief in restoring genuine worker democracy, which is why that option is identified as the best answer.
