On 16 March 1921 the Tenth Party Congress adopted a secret clause allowing expulsion for factionalism, in Lenin’s resolution on party unity. The Workers’ Opposition and Democratic Centralists were closed as organized platforms.

Context

Kronstadt was being stormed the same week. The ban is a party-statute Fact with later Stalin-era uses.

Shared responsibility with other offices is part of the record. Sharing is not a reason to drop this person's documented role, and it is not a reason to treat every later consequence as their handwriting.

Why it matters

What the sources establish

The resolution is in congress documents. Britannica records the 1921 ban. Schapiro independently reconstructs inner-party history.

Later commission estimates are attributed to those commissions.

Established: the 1921 faction ban. Not established: that Lenin intended the 1937 application.

Central files can show that an order was issued; they cannot reconstruct every locality's implementation. Memoir and literary evidence is independent texture, never the sole causal source. Official statistics of the period are treated as claims with known incentives. Later archival openings and museum publications are independent or successor-state records. The contribution is direct where this person signed, chaired, or issued the act, and remains bounded by other offices that had to act. Readers who want the welfare path should open the named driver rather than treating a portrait as the mechanism.
