I apologize, but I couldn't find specific details about the Tajikistan Grade 10 (Sinfi 10) History curriculum. The available information online only provides general information about education in Tajikistan, mentioning a competency-based curriculum introduced in 2015 and the use of Tajik, Russian, and English languages in instruction. The Aga Khan Lycée follows the Tajik National State Curriculum, but details about the specific content for Grade 10 History are not publicly available. Several searches related to the Ministry of Education and Science of the Republic of Tajikistan, Tajik history textbooks, and news about the national curriculum did not yield specific information about the Grade 10 History curriculum.
