Eugene tempered "Sicut dudum" with another bull (15 September 1436) due to the complaints made by King Duarte of Portugal, that allowed the Portuguese to conquer any unconverted parts of the Canary Islands. The king suggested that Portugal be authorized to evangelize and civilize the islands, as other less reputable persons were unlikely to heed the pontiff. Political weakness compelled the Renaissance Papacy to adopt an acquiescent and unchallenging position when approached for requests for privileges in favour of these ventures. Without a navy of his own to police the islands, the Pope opted in favor of the Portuguese as the lesser of two evils.
