East Iranian in the context of "Sakzai"

The Yaz culture (named after the type site Yaz-Tappe, Yaz Tepe, or Yaz Depe, near Baýramaly, Turkmenistan) was an early Iron Age culture of Margiana, Bactria and Sogdia (c. 1500–500 BC, or c. 1500–330 BC). It emerges at the top of late Bronze Age sites (BMAC), sometimes as mud-brick platforms and sizeable houses associated with irrigation systems. Ceramics were mostly hand-made, but there was increasing use of wheel-thrown ware. Bronze and iron arrowheads, iron sickles and carpet knives are among other artifacts that have been found.

With the farming citadels and absence of burials it has been regarded as a likely archaeological reflection of early East Iranian culture as described in the Avesta. So far, no burials related to the culture have been found, and this is taken as possible evidence of the Zoroastrian practice of exposure or sky burial.

The Scythian campaign of Darius I was a military expedition into parts of European Scythia by Darius I, the king of the Achaemenid Empire, in 513 BC. The Scythians were an East Iranian-speaking people who had invaded Media, revolted against Darius and threatened to disrupt trade between Central Asia and the shores of the Black Sea as they lived between the Danube and Don Rivers and the Black Sea. The campaigns took place in parts of what is now the Balkans, Ukraine, and southern Russia.

The Scythians managed to avoid a direct confrontation with the Persian army due to their mobile lifestyle and lack of any settlement (except Gelonus), while the Persians suffered losses due to the Scythians' scorched earth tactic. However, the Persians conquered much of their cultivated lands and damaged their allies, forcing the Scythians to respect the Persian force. Darius halted the advance to consolidate his gains, and built a defence line.
