Аламут
In 1090 AD, the Alamut Castle, a mountain fortress in present-day Iran, came into the possession of Hassan-i Sabbah, a champion of the Nizari Ismaili cause. Until 1256, Alamut functioned as the headquarters of the Nizari Ismaili state, which included a series of strategic strongholds scattered throughout Persia and Syria, with each stronghold being surrounded by swathes of hostile territory.
