Theodore II Doukas Laskaris or Ducas Lascaris was Emperor of Nicaea from 1254 to 1258.
Background
Theodore II Doukas Laskaris was the only son of Emperor John III Doukas Vatatzes and Eirene Laskarina, the daughter of Emperor Theodore I Laskaris and Anna Angelina, a daughter of Emperor Alexios III Angelos and Euphrosyne Doukaina Kamaterina. Theodore was born in late 1221 or early 1222, reportedly on the very day his father ascended the throne. In contrast with earlier practice, Theodore II was not crowned co-emperor with his father, though he assisted in the government since c.
Career
Theodore II received a scholarly education by Nicephorus Blemmydes who would become a tutor to him, and remained devoted to science and art throughout his life. On the death of John III on November 4, 1254, Theodore II was acclaimed emperor by the army and the court, but was crowned only after the appointment of a new patriarch, Arsenios Autoreianos, in 1255. The succession of Theodore was exploited by the Bulgarians, who invaded Thrace under the leadership of the young and inexperienced Michael Asen I of Bulgaria in 1255.
In spite of his own scholarly predisposition, Theodore immediately marched against the Bulgarians and inflicted a crushing defeat on them.
During his second expedition in 1256, he managed to conclude a favorable peace with Bulgaria, which may have plunged the latter into a crisis of leadership. Theodore followed up his victory against Bulgaria by expanding his control in the west, where he annexed Durazzo and Servia, effectively outflanking his rivals in Epirus.
Michael Angold explains this as in part, a matter of his temperament:
He was happier in the company of a cultivated circle of friends, some of whom had been his childhood companions (paidopoula). He clearly disliked what he considered the philistinism prevalent among a section of the young men at his father"s court.
Theodore"s favoring of commoners faced considerable opposition by the nobility to the Emperor and his chief minister, the megas domestikos George Mouzalon.
The conflict led to the exile of one of the leaders of the aristocratic faction, the future Emperor Michael VIII Palaeologus, who was accused of conspiring with the Seljuks of Rum. Theodore II Doukas Laskaris married Elena of Bulgaria, daughter of Ivan Asen II of Bulgaria in 1235, by whom he had several children including:
Irene Doukaina Laskarina, who married Constantine I of Bulgaria
Maria Doukaina Laskarina, who married Nikephoros I Komnenos Doukas of Epirus
These have been:
Theodora, who married Mathieu de Mons, baron of Veligosti
Eudoxia Laskarina who married Pietro I Count of Ventimiglia and Tende and Arnaud Roger Count of Pallars-Subirà
According to George Pachymeres Theodore had a fifth daughter, who might have been illegitimate, but who married Svetoslav, despot of Bulgaria. John IV Doukas Laskaris.
Membership
Internally, Theodore favored bureaucrats from the middle classes instead of members of the great aristocratic families.
