In February 1918, the First Congress of Soviets of the Kuban Region was held in Armavir.

[citation needed] That same day, many in attendance spoke in favor of uniting with the nearby Black Sea Soviet Republic.

[citation needed] Soon after the creation of the Kuban SR, the Council of People's Commissars was formed, which consisted of sixteen members.

The Kuban-Black Sea Military Revolutionary Committee, a joint command structure between the Kuban and Black Sea SRs, was formed soon after the creation of the Kuban SR.[citation needed] The Third Extraordinary United Congress of Soviets of the Kuban and Black Sea Soviet Republics was held in Yekaterinodar from May 28 to May 30, and was attended by 882 delegates.

On May 30, a proposal for a Central Executive Committee of the Soviets of the Kuban and Black Sea Republics was approved (despite protests from the Left SRs), and the Kuban-Black Sea Soviet Republic was proclaimed shortly after.
