Açina, also ššina, was one of the last kings of the kingdom of Elam, and ruled briefly in 522 BCE.
He was toppled by Darius I and later depicted in chains in the Behistun Inscription.
[2] According to Darius in his inscription: King Darius says: After I had slain Gaumâta, the Magian, a certain man named ššina, the son of Upadarma, raised a rebellion in Elam, and he spoke thus unto the people of Elam: 'I am king in Elam.'
And a certain Babylonian named Nidintu-Bêl, the son of Kîn-Zêr, raised a rebellion in Babylon: he lied to the people, saying: 'I am Nebuchadnezzar, the son of Nabonidus.'
That ššina was brought unto me in fetters, and I killed him.
