By virtue of this right the territories of Leontini, Carthage, and Corinth, the domanial property of the kings of Macedonia, Pergamus, and Cyrene, the mines in Spain and Macedonia were regarded as Roman domains; and, in like manner with the territory of Capua, were leased by the Roman censors to private contractors in return for the delivery of a proportion of the produce or a fixed sum of money. We have already explained that Gaius Gracchus went still farther, claimed the whole land of the provinces as domain, and in the case of the province of Asia practically carried out this principle; inasmuch as he legally justified the -decumae-, -scriptura-, and -vectigalia- levied there on the ground of the Roman state's right of property in the land, pasture, and coasts of the province, whether these had previously belonged to the king or private persons.(7)
There do not appear to have been at this period any royalties from which the state derived profit, as respected the provinces; the prohibition of the culture of the vine and olive in Transalpine Gaul did not benefit the state-chest as such. On the other hand direct and indirect taxes were levied to a great extent. The client states recognized as fully sovereign--such as the kingdoms of Numidia and Cappadocia, the allied states (-civitates foederatae-) of Rhodes, Messana, Tauromenium, Massilia, Gades--were legally exempt from taxation, and merely bound by their treaties to support the Roman republic in times of war by regularly furnishing a fixed number of ships or men at their own expense, and, as a matter of course in case of need, by rendering extraordinary aid of any kind.
Taxes
The rest of the provincial territory on the other hand, even including the free cities, was throughout liable to taxation; the only exceptions were the cities invested with the Roman franchise, such as Narbo, and the communities on which immunity from taxation was specially conferred (-civitates immunes-), such as Centuripa in Sicily. The direct taxes consisted partly--as in Sicily and Sardinia--of a title to the tenth(8) of the sheaves and other field produce as of grapes and olives, or, if the land lay in pasture, to a corresponding -scriptura-; partly--as in Macedonia, Achaia, Cyrene, the greater part of Africa, the two Spains, and by Sulla's arrangements also in Asia--of a fixed sum of money to be paid annually by each community to Rome (-stipendium-, -tributum-). This amounted, e. g. for all Macedonia, to 600,000 -denarii- (24,000 pounds), for the small island of Gyaros near Andros to 150 -denarii- (6 pounds, 10 shillings), and was apparently on the whole low and less than the tax paid before the Roman rule. Those ground-tenths and pasture-moneys the state farmed out to private contractors on condition of their paying fixed quantities of grain or fixed sums of money; with respect to the latter money-payments the state drew upon the respective communities, and left it to these to assess the amount, according to the general principles laid down by the Roman government, on the persons liable, and to collect it from them.(9)
Customs
The indirect taxes consisted--apart from the subordinate moneys levied from roads, bridges, and canals--mainly of customs-duties. The customs-duties of antiquity were, if not exclusively, at any rate principally port-dues, less frequently frontier-dues, on imports and exports destined for sale, and were levied by each community in its ports and its territory at discretion. The Romans recognized this principle generally, in so far as their original customs-domain did not extend farther than the range of the Roman franchise and the limit of the customs was by no means coincident with the limits of the empire, so that a general imperial tariff was unknown: it was only by means of state-treaty that a total exemption from customs-dues in the client communities was secured for the Roman state, and in various cases at least favourable term for the Roman burgess. But in those districts, which had not been admitted to alliance with Rome but were in the condition of subjects proper and had not acquired immunity, the customs fell as a matter of course to the proper sovereign, that is, to the Roman community; and in consequence of this several larger regions within the empire were constituted as separate Roman customs-districts, in which the several communities allied or privileged with immunity were marked off as exempt from Roman customs. Thus Sicily even from the Carthaginian period formed a closed customs-district, on the frontier of which a tax of 5 per cent on the value was levied from all imports or exports; thus on the frontiers of Asia there was levied in consequence of the Sempronian law(10) a similar tax of 21 per cent; in like manner the province of Narbo, exclusively the domain of the Roman colony, was organized as a Roman customs- district This arrangement, besides its fiscal objects, may have been partly due to the commendable purpose of checking the confusion inevitably arising out of a variety of communal tolls by a uniform regulation of frontier-dues. The levying of the customs, like that of the tenths, was without exception leased to middlemen.
Costs Of Collection
The ordinary burdens of Roman taxpayers were limited to these imposts; but we may not overlook the fact, that the expenses of collection were very considerable, and the contributors paid an amount disproportionately great as compared with what the Roman government received. For, while the system of collecting taxes by middlemen, and especially by general lessees, is in itself the most expensive of all, in Rome effective competition was rendered extremely difficult in consequence of the slight extent to which the lettings were subdivided and the immense association of capital.
Requisitions
To these ordinary burdens, however, fell to be added in the first place the requisitions which were made. The costs of military administration were in law defrayed by the Roman community. It provided the commandants of every province with the means of transport and all other requisites; it paid and provisioned the Roman soldiers in the province.
