# First Congress founds the Communist International in Moscow

Date: 1919

## The fact

On 2–6 March 1919 the First Congress of the Communist International met in Moscow and founded Comintern. Lenin was the principal Russian author of its orientation against the Second International.

Later speeches, cult, and measured outcomes are not mixed into this Fact.

## Context

This is an international-organization Fact, not a Soviet statute. Later 21 Conditions (1920) are a related tightening Fact.

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.

## Evidence and sources

Congress documents and [Lenin](/people/vladimir-lenin)’s 1919 article are official. Britannica independently dates the founding. Delegate authenticity was thin and is so recorded.

Official or archival record: Lenin, The Third International and Its Place in History, 1919 (https://www.marxists.org/archive/lenin/works/1919/mar/x04.htm; Marxists Internet Archive). Later commission estimates are attributed to those commissions.

## Significance

Initiating proxy/international-split path, medium confidence. Direct contribution.

## What is established and what is not

Established: Comintern was founded in Moscow in March 1919. Not established: that Lenin commanded every later foreign party.

What would change the picture: a contradictory original protocol with a different date or signatory; a demonstrated forgery; or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of war, weather, or unauthorized local action.

The documentary limit is the same for every instrument in this dossier. 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. They do not convert this Fact into a personality score and do not cancel the original instrument. 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.
