A law of the republic required every merchant trading to the East to bring back some material for the adornment of the fane.
The hindrance, however, to the general development of trade which the act involved aroused at once loud complaints, tO which Cromwell turned a deaf ear, continuing to seize Dutch ships trading in forbidden goods.
Longinus admitted that the Venetians were indeed "a great people with a strong habitation"; but by dint of promising large concessions and trading privileges, he induced the Venetians to make an act of submission - though not upon oath.
But it was inevitable that, when the barbarians, Lombard or Frank, were once established on the mainland of Italy, Venice should be brought first into trading and then into political relations with their near neighbours, who as masters of Italy also put forward a claim to sovereignty in the lagoons.
Rivalry in fishing and in trading, coupled with ancient antipathies inherited from the various mainland cities of origin, were no doubt the cause of these internecine feuds.
