Nizam al-Mulk, the vizier and the de facto ruler of the Seljuk Empire, was assassinated in 1092 by the Nizaris. It was the most prominent and the first of the fifty assassinations performed during Hassan-i Sabbah's leadership.
The Nizari commander Buzurg-Ummid captured Lamasar (now in ruins) and rebuilt it into the biggest Nizari fortress. The Nizari strongholds were built to withstand long sieges (for example, Gerdkuh, a similar fortress resisted a Mongol siege of 17 years).
