The Second International (1889–1916) was an organisation of socialist and labour parties, formed on 14 July 1889 at two simultaneous Paris meetings in which delegations from twenty countries participated. The Second International continued the work of the dissolved First International, though excluding the powerful anarcho-syndicalist movement. While the international had initially declared its opposition to all warfare between European powers, most of the major European parties ultimately chose to support their respective states in World War I. After splitting into pro-Allied, pro-Central Powers, and antimilitarist factions, the international ceased to function. After the war, the remaining factions of the international went on to found the Labour and Socialist International, the International Working Union of Socialist Parties, and the Communist International.
The Spartacus League was a Marxist revolutionary movement organized in Germany during World War I. It was founded in August 1914 as the International Group by Rosa Luxemburg, Karl Liebknecht, Clara Zetkin, and other members of the Social Democratic Party of Germany (SPD) who were dissatisfied with the party's official policies in support of the war. In 1916 it renamed itself the Spartacus Group and in 1917 joined the Independent Social Democratic Party of Germany (USPD), which had split off from the SPD as its left wing faction. During the November Revolution of 1918 that broke out across Germany at the end of the war, the Spartacus Group re-established itself as a nationwide, non-party organization called the "Spartacus League" with the goal of instituting a soviet republic that would include all of Germany. It became part of the Communist Party of Germany (KPD) when it was formed on 1 January 1919 and at that point ceased to exist as a separate entity.
