the "Three Gauls" as well as those of Provincia, whatever their form of government, conducted their affairs with senate, magistrates and police of their choosing, had their municipal property, and controlled their internal finances. A diet was established for the "Three Gauls" at Lyons, to which the cities sent delegates. Whatever were its powers, its existence tended to foster a sense of common Gallic nationality. The Roman franchise, however, was but sparingly bestowed on individuals, and was not granted to any Gallic city (except Lyons) until the time of Claudius, himself born at Lyons. He refounded Cologne as a colony, granted the franchise to Trèves, and abolished the provisions forbidding Gauls to hold the imperial magistracies. With the reorganization of the Empire under Diocletian, Trèves became the capital not only of Gaul, but of Spain and Britain also.
Although there was thus no violent Romanization of Gaul, Roman civilization rapidly progressed under imperial fostering, and by virtue of its own energy. Roman roads traversed the country; bridges spanned the rivers; aqueducts were constructed; cities grew, trade increased, agriculture improved, and the vine was introduced. At the time of Caesar's conquest, the quick-minded Gauls were prepared to profit from a superior civilization; and under the mighty peace of Rome, men settled down to the blessings of safe living and law regularly enforced.
The spread of the Latin tongue and the finer elements of Latin culture followed the establishment of the Roman order. One Gallic city and then another adopted the new language according to its circumstances and situation. Of course the cities of Provincia took the lead, largely Italian as they were in population. On the other hand, Latin made slow progress among the hills of Auvergne. But farther north, the Roman city of Lyons was Latin-tongued from its foundation. Thence to the remoter north and west and east, Latin spread by cities, the foci of affairs and provincial administration. The imperial government did not demand of its subjects that they should abandon their native speech, but required in Gaul, as elsewhere, the use of Latin in the transaction of official business. This compelled all to study Latin who had affairs in law courts or with officials, or hoped to become magistrates.
