# Taxation districts of the Achaemenid Empire

Herodotus divided the Achaemenid Empire into 20 districts for the purpose of tribute payments. The following is a description of the ethnic makeup of the districts and the amount they paid in taxes, translated from Herodotus' Histories.

## Accounting units

The quantities of silver are given in Babylonian talent (1 Babylonian talent = about 30.3 kg), while the quantities of gold (India only) are given in Euboïc/Euboean talent (1 Euboïc talent = about 26 kg). Only the Hindush paid in gold, the exchange rate of gold to silver being 1 to 13 by weight at the time of Herodotus.

## Tax districts

The order of the districts given here follows Herodotus, Histories, III.90–94. In hellenocentric way it starts with Ionia and Mysia. The official Persian order of the provinces, as devised under Darius I in 518 BCE, was different and started from the Empire's capital: 1. Media, 2. Susa, etc. For comparison, it is given in the rightmost column.
