The scientist visited the Archive of the Federal Foreign Office of Germany in Berlin and expressed interest in the availability of sources related to the history of the Uzbek people, statehood, as well as Turan–Turkestan.

It is reported that the archive management expressed support for the Institute of History's research in this direction and stated that the necessary conditions would be created for researchers. Furthermore, the scientist was introduced to a number of valuable and rare documents preserved in the archive.

Among the identified sources, there are materials relating to young people sent from our country to German higher education institutions for studies in the 1920s. In addition, documents were found regarding the activities of the cultural commission established in Germany to support them, the history of the Bukharan People's Soviet Republic, and the Jadid enlightener Khairiniso Majidkhonova.

These sources will allow introducing new data into scientific circulation regarding the educational policy, international relations, and history of the national intelligentsia of Uzbekistan at the beginning of the 20th century.
