Tapuri

Tapuri or Tapyri (Ancient Greek: Τάπουροι or Τάπυροι or Τάπυρροι)[1][2] were a tribe in the Medes south of the Caspian Sea mentioned by Ptolemy and Arrian.

[4] The name and probable habitations of the Tapuri appear, at different periods of history, to have been extended along a wide space of country from Armenia to the eastern side of the Oxus.

Then he forced them to leave southern fringes of Caspian Sea and replaced them with Tapur people.

[14] These Tapuri clan furnished 1,000 cavalry for the battle of Gaugamela as Achaemenid Empire Army.

[15] According to Arrian, a group of Tapurs lived among the Hyrcanians and Amards during the Achaemenid and Alexander periods.
