The aim of this study is to explore the foundations of the nation's rights (with an emphasis on freedom) within the intellectual system of Imam Khamenei. The research employs a rational method and a descriptive-analytical approach, and the data have been collected through a systematic study of his speeches and directives. The findings indicate that the foundations of the nation's rights in his thought can be explained at two levels: conceptual foundations, which address the definition and nature of the nation's rights and the theoretical framework necessary for their interpretation and implementation within the Constitution of the Islamic Republic of Iran. The affirmational foundations (taṣdīqī) are also examined in two categories—"remote" (dor) and "proximate" (nazdik): the remote foundations rest on components such as an ontology based on the continuity of divine guardianship (wilāyah), an epistemology that integrates religious rationality with social experience, a methodology including dynamic ijtihad, the Constitution as an executive framework, an anthropology based on free will, responsibility, and spirituality, and a sociology based on religious democracy. The proximate foundations are dedicated to the principles and practical factors that realize the nation's rights within the Islamic system.
