#imperial charter
- Ahdname — An archaic graphic and phonetic form (attested in old Romanian chronicles) for ahdiname; an official diplomatic treaty, solemn charter, or imperial decree through which the sultans of the Ottoman Empire granted specific legal privileges, structural autonomy, protection, or commercial freedoms to vassal states (such as the Romanian Principalities) or Christian subjects. These documents established the legal framework for bilateral relations and represented a sacred imperial guarantee.
