Avestan geographyAvestan geography refers to the investigation of place names in the Avesta and the attempt to connect them to real-world geographical sites. It is therefore different from the cosmogony expressed in the Avesta, where place names refer to mythical events or a cosmological order. Identifying such connections is important for localizing the people of the Avesta and is therefore crucial for understanding the early history of Zoroastrianism and the Iranian peoples.
Sufi dynastyThe Sufid dynasty was a Turkic dynasty of Mongolic origin that ruled in Khwarazm within the realm of the Golden Horde in the Amu Darya river delta. Although the dynasty's independence was short-lived (c. 1361 – 1379), its later members continued to rule Khwarezm intermittently as governors of the Timurid Empire until the takeover of Khwarezm by the Shaybanid Uzbeks in 1505. Unlike earlier dynasties that ruled from Khwarezm, the Sufids never used the title Khwarazmshah.
EdiguEdigu (or Edigey) (also İdegäy or Edege Mangit) (1352–1419) was a Mongol Muslim emir of the White Horde who founded a new political entity, which came to be known as the Nogai Horde. Edigu was from the Crimean Manghud tribe, the son of Baltychak, a Mongol noble who was defeated and killed by Khan Tokhtamysh of the Golden Horde in 1378. He gained fame as a highly successful general of Tokhtamysh before turning the arms against his master.
Sasanian dynastyThe Sasanian dynasty (also known as the Sassanids or the House of Sasan) was the house that founded the Sasanian Empire of Iran, ruling this empire from 224 to 651 AD. It began with Ardashir I, who named the dynasty in honour of his predecessor, Sasan. The Shahanshah was the sole regent, head of state and head of government of the empire. At times, power shifted de facto to other officials, namely the spahbed.
