The 马穆鲁克 are perhaps the easiest country to form Arabia with, as they have many of the required provinces and 汉志 as a vassal, also getting an event to annex 麦地那 once it has been vassalised, adding more of the required land to the Mamluks after diplomatic annexation. Since the Mamlukian government (Sultanate) gets increased vassal income and the Arabian minors are generally easy to force into vassalization, it is recommended to do just that. Don't waste admin points in Arabian peninsula. Instead, vassalize the Arabian minors peacefully or forcefully and diploannex them as soon as possible. The player's next step will be taking Baghdad from 黑羊 since it is necessary to form Arabia. It is also recommended to take the other culturally Mashriqi lands since the player will have a permanent claim on them as Arabia and will want to take it before the Ottomans do. The last part, but not the least, is the 奥斯曼. With this foe the player will need luck and diplomacy. It is advisable to ally 突尼斯 and a powerful European nation that has rivaled the Ottomans in the early game, like 波兰 or 奥地利, and fortify the border with the Ottomans to prevent any unwanted Ottoman aggression.
有安达卢西亚主流文化意味着 格拉纳达 需要转换文化，一旦它们已经在北非取得进展并且获得要求的领土。This is necessary as Bedouin should become majority culture once all of Arabia is conquered. If this isn't the case then Granada expanded the Andalusian culture too much, or using Common Sense expansion developed the Iberian territories too well. This can be fixed by either also developing the Arabian desert provinces, creating vassals and giving them Granada's Iberian lands until it is possible to change primary culture and reannexing them, and unstating Iberian provinces.
For players aiming to get the Sworn Fealty achievement, 内志 is the stronger contender of the weak landlocked tribal federations.
Early game is a land race with the 马穆鲁克 who will passively absorb the Hejazi minors within the first 100 years. However the player can generally ally the Mamluks at the start to ward away hungry neighbors. Priority nations to conquer would be 萨玛尔 to the north and 代瓦西尔 and 米克利夫 to the south to contain Mamlukean expansion on the peninsula. From there follow the winds of fortune to pick off weak neighbors to consolidate the peninsula under your banner. The player should aim to border the Syrian provinces of the Mamluks before breaking the alliance to trade up to the 奥斯曼. Blitz Aleppo in the first war and strive to be the war leader at all times in the Mamluk/Ottoman wars to control the peace deal.
