THE ARMENIAN QUESTION AT THE LAUSAN CONFERENCE – 2023-2 To the 100th anniversary of the signing of the Treaty of Lausanne on July 24, 1923 Armen Ts. Marukyan In the process of signing the Lausanne Treaty, the mandatory conditions and procedures for amending international treaties were not observed. Since neither the subjects nor the parties of the two treaties are identical, there is no reason to argue that the Treaty of Sèvres has been legally superseded by the Treaty of Lausanne. Based on this, it can be stated that the rights of the state parties to the Treaty of Sevres that are not parties to the Treaty of Lausanne, from a legal point of view, could not undergo any changes, in particular, the Treaty of Lausanne did not introduce any changes into the provisions of the Treaty of Sèvres regarding the rights and interests of Armenia.
