9. The Coinage
1. Origins
Aksum was the only African state in ancient times, outside the Roman dependencies, to
issue its own national coinage (for references on coinage questions see Anzani: 1926,
1928, 1941; Munro-Hay, loc. var: Hahn 1983; much of the following chapter is based on
Munro-Hay 1984iv). The Aksumite coinage lasted from about 270AD, or a little later,
into the early seventh century, and seems to have been used in both external trade and
internal market transactions. How far the whole kingdom was able to employ a
monetarised economy is still a matter for conjecture, but so far coin- finds have been
reported from all excavated Aksumite sites.
By the time of Aksum's first recorded
military ventures to the Yemen, the coinage of the
South Arabian kingdoms would seem to have been nearing the end of its use, if it was not
already discontinued. This coinage, chiefly of silver in Saba and Himyar, and bronze in
Hadhramawt, only very rarely seems to have included electrum or gold pieces. It is much
more likely that the immediate origins of the coinage of Aksum were influenced by
Roman trading in the Red Sea, though perhaps the awareness of Kushana and Persian
coinages also inspired the Aksumites to emulation. The Aksumite coinage followed the
Roman/Byzantine
weight system, and this and certain other factors add probability to the
suggestion that Rome was the primary region to which Aksum looked when the issue of a
coinage was planned. At any rate, adoption of a coinage would have immensely
facilitated exchange of products and all other public and private business in which it was
employed, and must have given considerable impetus to the economy.
Whilst the re is no actual proof, except for the tentative identification of a pottery object
from the excavations as a coin- mould (Wilding in Munro-Hay 1989), it would seem very
likely that it was at Aksum itself that the coins were minted. No other African state south
of the Sahara issued coins until the sultanate of Kilwa began coinage-production possibly
in the mid-tenth century.
2. Introduction and Spread of the Coinage
Few African societies possessed a market or exchange system so evolved as to require a
universally accepted form of currency; the need for such a currency stands in a direct
ratio to the complexity of the society which has developed, and the ultimate expression of
the requirement for currency in the ancient world was a coinage system. Use of a general
purpose money evidently simplifies the system in representing the medium of exchange,
the standard of value- measurement, a means of holding wealth at discretion, and a means
of
payment for services, all in one form. As Plato commented, `
money reduces the
inequalities and immeasurabilities of goods to equality and measure'. A coinage,
fashioned from a precious metal, and of convenient size for representing large sums with
little weight and bulk, was also much more broadly recognised than other types of
currency in the international framework in which Aksum's trade became involved.
Coinage gave the economy a central emphasis from which every aspect of the state's
functions could spring. Wealth could pass easily in both local and external transactions,
so long as the standard conformed, and Aksum accordingly
linked its coinage with the
Romano-Byzantine monetary system.
Within the area of Aksum's control, circulation of the coinage could have been
encouraged by the demanding of coinage payments for certain taxes, by state payments
for military and other services in coinage, and by the gradual increase in the number of
merchants in the markets using it as the standardised medium of exchange. Commodities
formerly expressed in different values could be exchanged with this single easily-
controlled factor, and the rate of trade speeded up considerably. The traditional value of
each object in relation to a complex variety of others was thus centralised, and inevitably
the
simpler system would gain, as long as the ultimate guarantor, the Aksumite ruler, was
visibly apparent to support it. Gold and silver in the pure state are intrinsically valuable,
but in a debased currency, or a currency where the value in spending power is above the
real value of the metal it is of course only viable while the issuer represents the ultimate
redeemer. With token currencies, like the bronze, (though in Aksum the gilding might
have adjusted this to some extent) the real value of the coins was representative and not
actual.
Aksum's coinage was a successful experiment to judge from
its continuance reign after
reign for at least three hundred years. The combined factors of the power of the kings in a
military context, improving and increasing the possible routings for goods and providing
for their greater security, and the centralising of the spheres of commerce in a monetised
economy, must have supplied to trade a steady climate of increase. It has been observed
that the issue of a coinage generally stimulates an economy, and Aksum was no
exception. The increasingly complex trade would have been much more easily dealt with
after Aksum had entered the world of its trading neighbours with a monetary system on a
par with theirs.
At the time of the
Periplus,
the Aksumite state imported orokhalkos or brass "
which they
use for ornaments and for cutting as money", and "
a little money (denarion) for
foreigners who live there" (Huntingford 1980: 21-2). The use of metal as money before
the issue of a minted coinage certainly hints that the Aksumites were aware even at that
time of the advantages of a currency which did not require special care or maintenance
and was divisible at need. Neither Zoskales, the ruler of the region at the time, nor his
successors for well over a century, issued their own coins and it would seem as if the
kingdom was only beginning to orient itself towards the use of coinage. The use of
Roman money among foreign residents and
merchants is not surprising, but the
Aksumites' or Adulites' use of cut brass is; possibly brass was a relatively costly item in
Ethiopia at the time. This comment in the
Periplus, seeming to imply that Aksum was
