A crucial factor - the Spanish presence in North Africa, in particular their successful control of Tunisia.

The origin of the Saad dynasty has a very strong religious color, relying on the charisma of the holy war and the leader of the order to serve the separation of the tribes, after the defeat of the Wattas dynasty in 1545, the ruler of Saad had to take in the tribal forces to find new war targets, and marching east became a natural choice.

But since Algeria fell to Khareddin, the Ottoman Empire's influence in the Maghreb has grown, and the expansion of the Saad dynasty to the east will inevitably confront the Ottomans.

The Osmans were not indifferent to the rise of Saad, and in 1550 Osman sent an envoy asking the first Sultan of the Saad dynasty, Mehmet. The Sheikh became a vassal of the Ottomans, but the Moroccan Sultan, who claimed to be of holy descent, mocked the Ottomans as mere fishermen.

Morocco was determined to make an alliance with the Spaniards, and Morocco and the Ottomans continued to intervene in the kingdom of Tremcen to prop up their puppets. In 1551, the Moroccan occupation of Tlemcen caused a response from the Ottomans, and Hassan Brown, the son of Hayreddin. Pasha led his troops to defeat the Moroccan army in 0.

在占领特莱姆森后奥斯曼继续向非斯挺近，并扶持了瓦塔斯王朝的末裔哈苏恩以试图控制摩洛哥，在奥斯曼的帮助下1554年瓦塔斯王朝成功在非斯复辟，但同年哈苏恩又在塔德拉战役中被穆罕默德.谢赫击败。

Later, Morocco marched again on Tlemcen and helped the Ottomans during the siege of Oran (1558), but in the year 0 Muhammad. The assassination of the Sheikh by Ottoman soldiers, forcing the Moroccans to withdraw from Tlemcen, also sparked internal unrest, with a number of potential heirs to the throne seeking refuge in Algiers. All this led to another Ottoman attack on Morocco in 0. Thanks to the Spanish attack on Mustaganem in 0, the Ottoman army withdrew from Morocco.

Up to this point, the main opponent of the Moroccan Sultan was the governor of Algeria, and Suleiman rarely focused on the border provinces of the western Mediterranean, 1551-0 to a little more. This was largely due to Spanish influence on Tunisia, which separated Algeria from the Ottoman proper, but the Ottomans continued to attack eastern Tunisia since 0.

虽然1558年遭遇惨败，但1559年与法国的议和使得西班牙有更多资源可以投入到北非战线上，这也导致了1560年在杰尔巴岛的失败想，这场惨败彻底动摇了摩洛哥人的信心。

However, the victory of the Spaniards under Oran and the victory in Malta in 1568 announced that this great confrontation in the Mediterranean has not yet come to an end. However, with the great revolt of the Moriscos in 0, Spain was forced to take its energy away from the Mediterranean theater, during which the Ottomans not only succeeded in capturing Tunisia (0) and connecting their North African possessions, but also ordered the governor of Algiers to find the exiled prince with the largest supporters in Morocco in 0, which prompted Malik, one of the protagonists of the later Battle of the Three Kings, to go to Istanbul.

However, with Selim II's invasion of Cyprus leading to the formation of the Holy Alliance, Selim gave his naval commander an order to overthrow the Moroccan Sultan in order to bolster the Ottoman proxies before the Battle of Lepanto.

But all this changed with the Battle of Lepanto, where the Ottomans' elite navy was battered by the Holy Alliance, and although the Ottomans quickly rebuilt the fleet, it was clear that the prestige of the empire was hit, and in 1573 the Moroccans killed Abdul Mumin, one of the Ottomans' supporters. By 0, there were even rumors that the Moroccan Sultan was planning to attack Tlemcen, which forced the Ottoman Sultan to write a letter to the Saad Sultan calling for peace among Muslims against the Christians.

Although the Ottomans recaptured Tunisia in 1574 with a very remarkable and risky military campaign, the Great Mediterranean confrontation came to an end as the two empires turned their energies to other fronts (Lowlands vs. Persia).

But Morocco is still experiencing the final fallout 12 of the Saad Civil War, Malik with 0 Ottoman infantry, 0 lancers, 0 horse musketeers, 0 artillery under the patronage of the Ottomans tried to seize the throne of Morocco, and he did achieve an incredible military victory in the civil war, forcing Muhammad to ask the Iberian monarch for help.

The Spaniards had no intention of starting another war in the Mediterranean, and Malik wanted to avoid being completely controlled by the Ottomans after ascending to the throne, hoping to find a balance between the Ottomans and the Iberians, but King Sebastian of Portugal could not tolerate the expansion of Ottoman power and started the War of the Three Kings.

I have described the battle in detail before, and I will not repeat it here, except for a very unintended effect, because the Ottoman and the Portuguese support were killed at the same time, Mansour succeeded in ascending to the throne, and he did not carry the strong Ottoman mark like Malik, so Morocco can be said to have once again balanced the scales.

During the Mansour period, Morocco still maintained its relatively high national power, but after the Ottoman-Spanish war in the Mediterranean, its North African territory became increasingly localized, and the Barbary pirates, who had been assisted by the Ottoman navy in the past, became a problem for the Empire, ignoring the agreements between the Ottoman and friendly countries, plundering and even forcing the Tunisian governor to patrol the coast to protect merchant ships.

The Gordons were well aware of the increasing feudalization of their North African territories, but were willing to turn a blind eye to them as long as they did not attempt to overthrow Ottoman rule. After the death of Mansour, Morocco's internal division could not be suppressed, and the Moroccan Sultanate also moved towards internal division.
