Gāhānbar

Gāhānbar was an important financial and administrative institution in medieval Persia, particularly during the Sasanian Empire. It served as a central record-keeping office responsible for managing taxation, land assessments, and resource distribution. Essentially, the Gāhānbar collected and maintained detailed data about land quality, production, and revenue, ensuring efficient governance and fiscal stability. Its records helped the government allocate resources, enforce taxation, and oversee economic activities across the empire. The system was a precursor to modern administrative and statistical methods, playing a crucial role in maintaining the empire's infrastructure and financial health.
