Succession, continuity and legacy of the Soviet Union
The Union of Soviet Socialist Republics, commonly known as the Soviet Union was a transcontinental country that spanned much of Eurasia from 1922 to 1991. It was a founding member of the United Nations as well as one of the five permanent members of the United Nations Security Council (Soviet Union and the United Nations). Following the dissolution of the Soviet Union in 1991, its UN seat was transferred to the Russian Federation, the continuator state of the USSR.

 Background 
The Treaty on the Formation of the Union of Soviet Socialist Republics officially created the Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union. The Treaty was approved on 30 December 1922 by a conference of delegations from the Russian SFSR, the Transcaucasian SFSR, the Ukrainian SSR and the Byelorussian SSR. The Treaty and the Declaration were confirmed by the First All-Union Congress of Soviets and signed by heads of delegations Voted Unanimously for the Union  Mikhail Kalinin, Mikhail Tskhakaya, and Grigory Petrovsky, Alexander Chervyakov Creation of the USSR at Khronos.ru respectively on  December 30, 1922. The treaty provided flexibility to admit new members. Therefore, by 1940 the Soviet Union grew from the founding four (or six, depending on whether 1922 or 1940 definitions are applied) republics to 15 republics.

On 8 December 1991, Russian, Ukrainian and Belarusian leaders signed the Belovezha Accords. The agreement declared the dissolution of the USSR by its remaining founder states (denunciation of the Treaty on the Creation of the USSR) and established the Commonwealth of Independent States (CIS). On 10 December, the accord was ratified by the Ukrainian and Belarusian parliaments. On 12 December, the agreement was ratified by the Russian Parliament, therefore the Russian SFSR renounced the Treaty on the Creation of the USSR and de facto declared Russia's independence from the USSR.

On 26 December 1991, the USSR was self-dissolved by the Council of the Republics of the Supreme Soviet of the Soviet Union, the upper house of the Supreme Soviet of the Soviet Union (the lower house, the Soviet of the Union, was without a quorum).

 General agreements 

 UN membership 
On December 21, 1991, the Council of Heads of State decided that the member states of the Commonwealth, referring to Article 12 of the Agreement on the Establishment of the Commonwealth of Independent States, based on the intention of each state to fulfill obligations under the UN Charter and participate in the work of this organization as full members, taking into account that the original members of the UN were the Republic of Belarus, the USSR and Ukraine, expressing satisfaction that the Republic of Belarus and Ukraine continue to participate in the UN as sovereign independent states, decided that "the Commonwealth States support Russia in continuing the membership of the USSR in the UN, including permanent membership in the Security Council, and other international organizations."https://cis.minsk.by/reestrv2/doc/5#text The document entered into force for 11 countries on December 21.https://cis.minsk.by/reestrv2/doc/5#documentCard

On December 23, Russia officially received the USSR's seat on the UN Security Council. The international community recognized it as continuator state to the Soviet Union.

 International relations, treaties and organizations 
The "Guidelines on the Recognition of New States in Eastern Europe and the Soviet Union", adopted by Ministers of the EC on 16 December 1991.https://www.dipublico.org/100636/declaration-on-the-guidelines-on-the-recognition-of-new-states-in-eastern-europe-and-in-the-soviet-union-16-december-1991/

The Declaration of the Twelve on the future status of Russia and other former Soviet Republics was published on 23 December 1991, according to which "The European Community and its Member States have noted with satisfaction the decision of the participants at the Alma Ata meeting on 21 December 1991 to establish a Commonwealth of Independent States. They note that the international rights and obligations of the former USSR, including those arising from the Charter of the United Nations, will continue to be exercised by Russia. They note with satisfaction the acceptance by the Russian Government of these commitments and responsibilities and will continue to deal with Russia on this basis, taking into account the change in its constitutional status. They are prepared to recognise the other Republics constituting the Community as soon as they receive assurances from those Republics that they are prepared to fulfil the requirements set out in the "Guidelines on the Recognition of New States in Eastern Europe and the Soviet Union", adopted by Ministers on 16 December 1991. They expect, in particular, that those Republics will give them assurances that they will fulfil their international obligations arising from treaties and agreements concluded by the Soviet Union, including the ratification and implementation of the CFE Treaty by the Republics to which it applies, and that they will establish a single control over nuclear weapons and their non-proliferation."

Thus, the 12 countries (Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Luxembourg, Portugal, Spain, the Netherlands and the United Kingdom) do not need to recognize Russia's independence from the Soviet Union and establish new relations with Russia as a new state, because relations have already been established with the Soviet Union, of which Russia has become the continuator in international relations. Recognition of the independence of other 11 countries (Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Tajikistan, Turkmenistan, Ukraine, Uzbekistan) occurs on the condition that they assume the obligations under the treaties signed by the Soviet Union, including respect for the provisions of the Charter of the United Nations and the commitments subscribed to in the Final Act of Helsinki and in the Charter of Paris, guarantees for the rights of ethnic and national groups and minorities, respect for the inviolability of all frontiers and acceptance of all relevant commitments with regard to disarmament and nuclear non-proliferation as well as to security and regional stability.

 Debts and assets 
On December 4, 1991, 12 republics (except the Baltic states) signed an agreement on joint liability for repaying the USSR's debt to external creditors, according to which Russia's share was 61% of the Soviet debt. In order to leave the agreement on joint liability in the past, Russia proposed a "zero option". On April 2, 1992, it declared itself the sole legal successor to all debts of the former USSR and pledged to repay them in full, while receiving rights to all financial and material assets of the USSR. The remaining former Soviet republics could start with a "clean slate". In this case, they would have neither debts nor assets.
