The Daylamites or Dailamites were an Iranian people inhabiting the mountainous regions of northern Iran on the southern shore of the Caspian Sea. They were employed as soldiers from the time of the Sasanian Empire, and long resisted the Arab conquest of Iran and subsequent Islamization. In the 930s, the Dailami Buyid dynasty emerged and managed to gain control over much of modern-day Iran, which it held until the coming of the Seljuk Turks in the mid-11th century.
