Resume: The article examines the issue of Uzbekistan's place in matters of foreign policy and diplomatic activity in the system of the totalitarian Soviet state. The fact is substantiated that, in spite of the constitutional foundations given to the sovereign republics the right to independently conduct foreign policy activities, in practice they were limited. The reason for this was that an ideologized, command-administrative system of government dominated in the Union State, concentrated in the hands of the central body of the Communist Party. The situation has changed somewhat since the second half of the 40s of the 20th century. After the end of World War II, in connection with the change in the international situation in the world, some softening was made in relation to the representation of foreign policy on the part of the Union republics. On this basis, the Ministry of Foreign Affairs was established in Uzbekistan. However, the activities of this ministry were limited in the rights to conduct an independent foreign policy and participate in international relations. This is what the article proves that Uzbekistan, like other republics of the Union State, was given only the role of unquestioning executors of foreign policy guidelines imposed "from above". And in front of the world community, Uzbekistan was presented by the Union Center as a "showcase of the Soviet East", allegedly involved in full participation in international activities. But, in spite of all the harshness of the totalitarian regime, the Uzbek people, proceeding from the intellectual, economic, spiritual and moral potential of the republic, made every effort to represent Uzbekistan on the world stage, even on behalf of the USSR. In this regard, the article highlights the role of representatives of the Uzbek people who showed their talent in the diplomatic field on behalf of the Soviet state. Based on the agrarian-industrial, scientific and cultural-spiritual potential, the contribution of Uzbekistan to the development of the export potential of the Union State is revealed
