'Nicholas I Mystikos' or 'Nicholas I Mysticus' (
Greek: Νικόλαος Α΄ Μυστικός, ''Nikolaos I Mystikos'') (
852 –
May 15,
925) was the
Patriarch of Constantinople from March 901 to February 906 and from May 912 to his death in 925.
Nicholas was born in the
Italian Peninsula and had become a friend of the Patriarch
Photios. He fell into disfavor after Photios' dismissal in 886 and retired to a monastery. Emperor
Leo VI the Wise retrieved him from the monastery and made him ''mystikos'', a dignity designating either the imperial secretary or judicial official.
On
March 1,
901, Nicholas was appointed patriarch. However, he fell out with Leo VI over the latter's fourth marriage to his mistress
Zoe Karbonopsina. Although he reluctantly baptized the fruit of this relationship, the future
Constantine VII, Nicholas forbid the emperor from entering the church and may have become involved in the revolt of Andronikos Doukas. He was deposed as patriarch on
February 1,
907 and replaced by Euthymios. Exiled to his own monastery, Nicholas regarded his peposition as unjustified and involved the
Papacy in the dispute.
About the time of the accession of Leo VI's brother
Alexander to the throne in May 912, Nicholas was restored to the patriarchate. A protracted struggle with the supporters of Euthymios followed, which did not end until the new Emperor
Romanos I Lekapenos promulgated the ''Tomos of Union'' in 920. In the meantime Alexander had died in 913 after provoking a war with
Bulgaria, and the underage Constantine VII succeeded to the throne. Nicholas Mystikos became the leading member of the regency for the young emperor, and as such had to face the advance of
Simeon I of Bulgaria on
Constantinople. Nicholas negotiated a peaceful settlement, crowned Simeon emperor of the Bulgarians in a makeshift ceremony outside Constantinople, and arranged for the marriage of Simeon's daughter to Constantine VII.
This unpopular concession undermined his position, and by March 914 Zoe Karbonopsina overthrew Nicholas and replaced him as foremost regent. She revoked the agreement with Simeon, prompting the renewal of hostilities with Bulgaria. With her main supporter Leo Phokas crushingly defeated by the Bulgarians at the
Battle of Anchialus in 917, Zoe started to lose ground. Embarrassed by further failures, she and her supporters were supplanted in 919 by the admiral
Romanos Lekapenos, who married his daughter to Constantine VII and finally advanced to the imperial throne in 920. The Patriarch Nicholas came to be one of the strongest supporters of the new emperor, and took the brunt of renewed negotiations with the Bulgarians until his death in 925.
In addition to his numerous letters to various notables and foreign rulers (including Simeon of Bulgaria), Nicholas Mystikos wrote a homily on the sack of
Thessalonica by the
Arabs in 904. He was a critical thinker who went as far as to question the authority of
Old Testament quotations and the notion that the emperor's command was unwritten law.
