The Mussulman States of North Africa, at the commencement of Solyman’s reign, were in the hands of degenerate and incompetent Mahommedan rulers, who exercised little control over the Arabs of the hinterland. The cities on the coast were the haunts of pirates, who sometimes sailed under the flags of these States, but more often under no flag but their own. They preyed on the commerce of the Mediterranean, bringing their prizes into their ports and selling the captives as slaves, with the result that in Tunis alone there were twenty thousand Christian captives. These corsairs formed squadrons of ten or twenty galleys, under the command of admirals, chosen from the most daring and adventurous of them. They were called corsairs, but, in fact, they were mere pirates, knowing no law but their own, and that founded on robbery and murder. The sea-dogs in command of these pirates gained great experience in handling their ships and squadrons. They ravaged the coasts of Spain, Italy, and France, and even occasionally of England and Ireland, devastating the cities and villages and carrying away booty and captives. It has been shown that Selim paid great attention to his navy, and increased his ships in number and size. Solyman followed the same course. But his admirals and captains did not compare in skill and daring with those of the pirate squadrons. When Solyman became aware of this, he most astutely invited the ablest and most experienced of these pirates to take service under the Ottoman flag, and to bring with them their ships and men. He gave high appointments to them, raised them to the rank of admirals and commanders-in-chief of his navy, over the heads of the officers of his regular service.
