Some context: Al-Husayn ibn Ali ibn Abi Talib (Arabic: lHsyn bn `ly bn 'by Tlb; 10 October 625 - 10 October 680) (3 Sha'aban AH 4 (in the ancient (intercalated) Arabic calendar) - 10 Muharram AH 61) (his name is also transliterated as Husayn ibn 'Ali, Husain, Hussain and Hussein), was a grandson of the Islamic Nabi (Arabic: nabiy, Prophet) Muhammad, and son of Ali ibn Abi Talib (the first Shia Imam and the fourth Rashid caliph of Sunni Islam), and Muhammad's daughter, Fatimah. He is an important figure in Islam as he was a member of the Bayt (Arabic: bayt, Household) of Muhammad, and Ahl al-Kisa' (Arabic: 'ahl lkisa, People of the Cloak), as well as being the third Shia Imam.
According to the Shi'ah, Husayn was the third Imam for a period of ten years after the death of his brother Hasan in CE 669, all of this time but the last six months coinciding with the caliphate of Mu'awiyah. After the peace treaty with Hasan, Mu'awiyah set out with his troops to Kufa, where at a public surrender ceremony Hasan rose and reminded the people that he and Husayn were the only grandsons of Muhammad, and that he had surrendered the reign to Mu'awiyah in the best interest of the community: "O people, surely it was God who led you by the first of us and Who has spared you bloodshed by the last of us. I have made peace with Mu'awiyah, and I know not whether haply this be not for your trial, and that ye may enjoy yourselves for a time." declared Hasan.  In the nine-year period between Hasan's abdication in 41/660 and his death in 49/669, Hasan and Husayn retired in Medina trying to keep aloof from political involvement for or against Muawiyah.  Shi'ite feelings, however, though not visible above the surface, occasionally emerged in the form of small groups, mostly from Kufa, visiting Hasan and Husayn asking them to be their leaders - a request to which they declined to respond. Even ten years later, after the death of Hasan, when Iraqis turned to his younger brother, Husayn, concerning an uprising, Husayn instructed them to wait as long as Muawiyah was alive due to Hasan's peace treaty with him. Later on, however, and before his death, Muawiyah named his son Yazid as his successor.

Some context: Afonso de Albuquerque was born in 1453 in Alhandra, near Lisbon. He was the second son of Goncalo de Albuquerque, Lord of Vila Verde dos Francos, and Dona Leonor de Menezes. His father held an important position at court and was connected by remote illegitimate descent with the Portuguese monarchy. He was educated in mathematics and Latin at the court of Afonso V of Portugal, where he befriended Prince John, the future King John II of Portugal.
The fleet left Lisbon on 6 April 1506. Afonso piloted his ship himself, having lost his appointed pilot on departure. In Mozambique Channel, they rescued Captain Joao da Nova, who had encountered difficulties on his return from India; da Nova and his ship, the Frol de la mar, joined da Cunha's fleet. From Malindi, da Cunha sent envoys to Ethiopia, which at the time was thought to be closer than it actually is. Those included the priest Joao Gomes, Joao Sanches and Tunisian Sid Mohammed who, having failed to cross the region, headed for Socotra; from there, Afonso managed to land them in Filuk. After successful attacks on Arab cities on the east Africa coast, they conquered Socotra and built a fortress at Suq, hoping to establish a base to stop the Red Sea commerce to the Indian Ocean. However, Socotra was abandoned four years later, as it was not advantageous as a base.  At Socotra, they parted ways: Tristao da Cunha sailed for India, where he would relieve the Portuguese besieged at Cannanore, while Afonso took seven ships and 500 men to Ormuz in the Persian Gulf, one of the chief eastern centers of commerce. On his way, he conquered the cities of Curiati (Kuryat), Muscat in July 1507, and Khor Fakkan, accepting the submission of the cities of Kalhat and Sohar. He arrived at Ormuz on 25 September and soon captured the city, which agreed to become a tributary state of the Portuguese king.  Hormuz was then a tributary state of Shah Ismail of Persia. In a famous episode, shortly after it's conquest Albuquerque was confronted by Persian envoys, who demanded the payment of the due tribute from him instead. He ordered them be given a stock of cannonballs, arrows and weapons, retorting that "such was the currency struck in Portugal to pay the tribute demanded from the dominions of King Manuel"  According to Bras de Albuquerque, it was Shah Ismael who coined the term "Lion of the seas", addressing Albuquerque as such. Afonso began building the Fort of Our Lady of Victory (later renamed Fort of Our Lady of the Conception), engaging his men of all ranks in the work.  However, some of his officers revolted against the heavy work and climate and, claiming that Afonso was exceeding his orders, departed for India. With the fleet reduced to two ships and left without supplies, he was unable to maintain this position for long. Forced to abandon Ormuz in January 1508, he raided coastal villages to resupply the settlement of Socotra, returned to Ormuz, and then headed to India.
