Manuel II of Portugal
"Dom" Manuel II (15 November 1889 – 2 July 1932), "the Patriot" () or "the Unfortunate" (), was the last King of Portugal, ascending the throne after the assassination of his father, King Carlos I, and his elder brother, Luís Filipe, the Prince Royal. Before ascending the throne he held the title of Duke of Beja. His reign ended with the dissolution of the monarchy in the 5 October 1910 revolution, and Manuel lived the rest of his life in exile in Twickenham, South London.
Stephen III of Hungary
In short, Stephen III invaded Dalmatia, although he had pledged to Vitale II Michiel, Doge of Venice, that he would withdraw from the Dalmatian towns. Upon Stephen's arrival the citizens of Zadar expelled the Venetian governor and accepted his suzerainty. He again stormed into Sirmium and laid siege to his uncle in Zimony in spring 1165. Emperor Manuel decided to make a counterattack, but a rebellion by his cousin Andronikos Komnenos prevented him from marching to the Danube. Nevertheless, Manuel I sent envoys to the monarchs who had earlier supported Stephen III, persuading them to remain neutral in the conflict. Stephen III's uncle died of poisoning during the siege of Zimony, on 11 April. The fortress soon fell to Stephen III. The Byzantine counter-offensive started at the end of June. An army under the command of Emperor Manuel I laid siege to Zimony and recaptured it; an other Byzantine force invaded and occupied Bosnia and Dalmatia. The Venetian fleet intervened on the Byzantines' side in Dalmatia, forcing Zadar to again accept the rule of the Doge. Stephen III could only conclude a new peace treaty with Emperor Manuel after he renounced Sirmium and Dalmatia.
