Massilia flourished in spite of its isolation, and soon monopolized the trade of the region from Nice to the Pyrenees.
At the Pyrenees themselves Rhoda (now Rosas) was established as an offset from Lipara, and it is affirmed that Zacynthians settled in Saguntum, and even that Greek dynasts ruled at Tingis (Tangiers) in Mauretania.

But the Hellenes no longer gained ground; after the foundation of Agrigentum they did not succeed in acquiring any important additions of territory on the Adriatic or on the western sea, and they remained excluded from the Spanish waters as well as from the Atlantic Ocean.

Every year the Liparaeans had their conflicts with the Tuscan "sea-robbers," and the Carthaginians with the Massiliots, the Cyrenaeans, and above all with the Sicilian Greeks; but no results of permanent moment were on either side achieved, and the issue of struggles which lasted for centuries was, on the whole, the simple maintenance of the -status quo-.
Thus Italy was--if but indirectly--indebted to the Phoenicians for the exemption of at least her central and northern provinces from colonization, and for the counter-development of a national maritime power there, especially in Etruria.

But there are not wanting indications that the Phoenicians already found it worth while to manifest that jealousy which is usually associated with naval domination, if not in reference to their Latin allies, at any rate in reference to their Etruscan confederates, whose naval power was greater.

The statement as to the Carthaginians having prohibited the sending forth of an Etruscan colony to the Canary islands, whether true or false, reveals the existence of a rivalry of interests in the matter.
