In the far north of Sistān and Balūchestān, the people are mostly Persians and speak a dialect of the Persian language known as sistani/seestani, similar to the Dari Persian language in Afghanistan. The name Balūchestān means "Land of the Balōch" and is used to represent the majority Baloch peoples inhabiting the province, Sistan was added to the name to represent the minority Persian peoples who speak the sistani dialect of Persian.
Many scholars, orators, and literary personalities have sprung up from this part of Iran, amongst which are Farrukhi Sistani, Ya'qub bin Laith as-Saffar and Rostam. Ayatollah Sistani is also from Sistān; though he currently resides in Najaf, Iraq .
In the epigraphs of Bistoon and Persepolis, Sistan is mentioned as one of the eastern territories of Darius the Great. The name Sistan, as mentioned above, is derived from Saka (also sometimes Saga, or Sagastan), one of the Aryan tribes that had taken control over this area in the year 128 BCE. During the Arsacid Dynasty (248 BC to 224 CE), the province became the seat of Suren-Pahlav Clan. From the Sassanid period till the early Islamic period, Sistan flourished considerably.
During the reign of Ardashir I of Persia, Sistan came under the jurisdiction of the Sassanids, and in 644CE, the Arab Muslims gained control as the Persian empire was in its final moments of collapsing.
During the reign of the second caliph of Islam,Omar ibn Al-Khattab, this territory was conquered by the Arabs and an Arab commander was assigned as governor. The famous Persian ruler Ya'qub-i Laith Saffari, whose descendants dominated this area for many centuries, later became governor of this province. In 916 CE, Baluchestan was ruled by the Daylamids and thereafter the Seljuqids, when it became a part of Kerman. Dynasties such as the Saffarids, Samanids, Qaznavids, and Seljuqids, also ruled over this territory.
In 1508 CE, Shah Ismail I of the Safavid dynasty conquered Sistan, and during the reign of Nader Shah there was further turmoil.
