Alexander ordering the dismissal of PatriarchEuthymius.
Upon the death of his brother Leo on 11 May 912, Alexander succeeded as senior emperor alongside Leo's young sonConstantine VII. He was the first Byzantine emperor to use the term "autocrator" (αὐτοκράτωρ πιστὸς εὑσεβὴς βασιλεὺς) on coinage to celebrate the ending of his thirty-three years as co-emperor.[14] Alexander promptly dismissed most of Leo's advisers and appointees, including the admiralHimerios, the patriarchEuthymios, and the empressZoe Karbonopsina, the mother of Constantine VII, whom he locked up in a nunnery.[14] The patriarchate was again conferred onNicholas Mystikos, who had been removed from this position due to his opposition to Leo's fourth marriage.
Emperor Alexander rebuffs theBulgarian envoys, refusing to pay tribute.
During his short reign, Alexander found himself attacked by the forces ofAl-Muqtadir of theAbbasidCaliphate in the east, and provoked a war withSimeon I of Bulgaria by refusing to send the traditional tribute on his accession. Alexander died soon after, allegedly from astomach disease caused by excessive eating and alcohol.[15]
On his deathbed, Alexander finally concedes power to his nephewConstantine VII.
The sources are uniformly hostile towards Alexander, who is depicted as lazy, lecherous, drunk, and malignant; they also accuse him of idolatry, including makingpagan sacrifices to thegolden statue of aboar in theHippodrome, and providing it with new teeth and genitals, in hope of curing hisimpotence.[16] It was his rumored intention to castrate the young Constantine VII in order to exclude him from the succession. This did not happen, but Alexander did leave Constantine a hostileregent (Nicholas Mystikos) and the beginning of along war againstBulgaria.
^There is some evidence that Alexander was already crowned by August 879, but most sources agree that he was appointed co-emperor following the death of his brotherConstantine.[1][2] He was certainly made co-emperor before November 879.[3]
^Alexander is most commonly not assigned a regnal number.[6][7][8] If assigned one, he is rarely regarded asAlexander II, afterSeverus Alexander (r. 222–235)[9] or even more rarely asAlexander III[10] after both Severus Alexander andDomitius Alexander (r. 308–310). He has also been calledAlexander I.[11]
^Skylitzes, Ioannes (2010) [1100].Synopsis of History. Translated by John Wortley. p. 190.[Alexander] came down to play ball (tzykanion). A pain arose in his entrails which had been overloaded with an excess of food and excessive drinking. He went back up into the palace haemorrhaging from his nose and his genitals; after one day he was dead.
