Ruzbahan

Ruzbahan ibn Vindadh-Khurshid , better known as Ruzbahan (also spelled as Rezbahan), was a Daylamite military officer who served the Buyid dynasty. A native of Daylam, Ruzbahan began serving the Buyids at an unknown date and quickly rose into high ranks. After constant pressure from king Mu'izz al-Dawla to conquer Batihah, he, along with his two brothers, started a rebellion lasting from 955 to 957. After the end of the rebellion, Ruzbahan was imprisoned and shortly executed.
