P: Blanche of Navarre, however, proved to be an incredibly strong and efficient regent, and had devoted herself for the past 15 years to ensuring the legal status of her son Theobald IV as rightful heir.  Blanche was aided in securing her powerbase during the first few shakey years of her regency by the fact that so many lords and knights of the county, who might have posed a challenge to her, had left to fight on the Fourth Crusade from 1202 to 1204.  Queen Mother Adèle of Champagne  also took Blanche under her wing, giving Blanche vital counsel during the early years of her regency until Adèle's death in 1206 . By 1216, despite the fact that Erard rallied most of the local barons of the county against Blanche, she had built up such strong alliances with both King Philip II as well as Pope Innocent III that Erard never gained any official legal support for his claims.  From the start of the conflict, Pope Innocent III began excommunicating rebel barons, negatively affecting their efforts.  Further, while Theobald IV was still an underaged youth of 13 years, he had acquitted himself so valiantly in combat at the decisive Battle of Bouvines that King Philip II threw his full support behind him .

P: In 1505 the Mamluk Sultan Qansuh al-Ghuri ordered the first expedition against the Portuguese.The fleet was built with timber and weapons from the Ottoman Empire, and crews and shipwrights were recruited throughout the eastern Mediterranean. The expedition, under Amir Husain Al-Kurdi, left Suez in November and travelled by sea to Jidda, where they fortified the city. The fleet then prepared itself to go to Aden. This coincided with the dispatch of the 7th Portuguese India Armada into the Indian Ocean, under Francisco de Almeida. In 1506, another fleet under Afonso de Albuquerque started to raid the coasts of Arabia and the Horn of Africa, after defeating a Muslim fleet. In 1507, a fleet of about 20 Portuguese ships entered the Red Sea and raided Indian shipping there, bringing the Mamluk Indian trade to near collapse. The Portuguese attempted to establish a base at Socotra in 1507 in order to stop the Mamluk trade through the Red Sea, but the island proved too inhospitable and was ineffective in that role, so that the Portuguese left after a few months. In August-September 1507, the Mamluk fleet of about 50 vessels was stationed at Aden, preparing to go to India.
