'''John III Doukas Vatatzes''' or '''Ducas Vatatzes''' ([[Greek Language|Greek]]: Ιωάννης Γ΄ Δούκας Βατάτζης, ''Ioannes III Doukas Batatzes'') (c. [[1192]] – [[November 3]], [[1254]]) was [[Byzantine Emperor|emperor]] of [[Empire of Nicaea|Nicaea]] [[1221]]–[[1254]].

==Life==

John Doukas Vatatzes was probably the son of the general Basil Vatatzes by an unnamed cousin of the Emperors [[Isaac II Angelos]] and [[Alexios III Angelos]].

A successful soldier from a military family, in [[1212]] John was chosed by Emperor [[Theodore Laskaris]] as husband of his daughter [[Irene Lascaris|Eirene Laskarina]] and as heir to the throne. This arrangement excluded members of the Laskarid family from the succession, and when John III Doukas Vatatzes became emperor in mid-December [[1221]], he had to suppress opposition to his rule. The struggle ended with a battle in [[1224]], in which his opponents were defeated in spite of the support they had acquired from the [[Latin Empire]] of [[Constantinople]]. John III's victory led to territorial concessions by the Latin Empire in [[1225]], but was followed by John's incursion into Europe, where he seized [[Adrianople]].

John III's possession of Adrianople was terminated by [[Theodore I Ducas|Theodore Komnenos Doukas]] of [[Despotate of Epirus|Epirus]] and [[Thessalonica]], who drove the Nicaean garrison out of Adrianople and annexed much of [[Thrace]] in [[1227]]. The elimination of Theodore by Ivan Asen II of Bulgaria in [[1230]] put an end to the danger posed by Thessalonica, and John III made an alliance with Bulgaria against the Latin Empire. In [[1235]] this alliance resulted in the restoration of the Bulgarian patriarchate and the marriage between Ivan Asen II's daughter and John III's son. In the same year the Bulgarians and Nicaeans campaigned against the Latin Empire, and in [[1236]] they attempted a siege of Constantinople. Subsequently Ivan Asen II adopted an ambivalent policy, effectively becoming neutral, and leaving John III to his own devices.

In spite of some reverses against the Latin Empire in [[1240]], John III was able to take advantage of Ivan Asen II's death in [[1241]] to impose his own suzerainty over Thessalonica (in [[1242]]), and later to annex this city, as well as much of Bulgarian Thrace in [[1246]]. Immediately afterwards, John III was able to establish an effective stranglehold on Constantinople in [[1247]]. The last years of his reign saw the extension of Nicaean authority far to the west, where John III attempted to contain the expansion of [[Despotate of Epirus|Epirus]].

John III Doukas Vatatzes was a successful ruler who laid the groundwork for Nicaea's recovery of Constantinople. He was successful in maintaining generally peaceful relations with his most powerful neighbors, Bulgaria and the Sultanate of Rüm, and his network of diplomatic relations extended to the Holy Roman Empire and the Papacy, while his armed forces included Frankish mercenaries.

John III effected Nicaean expansion into Europe, where by the end of his reign he had annexed his former rival Thessalonica and had expanded at the expense of Bulgaria and Epirus. He also expanded Nicaean control over much of the [[Aegean Sea|Aegean]] and annexed the important island of [[Rhodes]].

Moreover, John III is credited with carefully developing the internal prosperity and economy of his realm, encouraging justice and charity. In spite of his [[epilepsy]], John III had provided active leadership in both peace and war. At some point after his death, John III was canonized as a saint, under the name John the Merciful.

==Family==

John III Doukas Vatatzes married first Eirene Laskarina, the daughter of his predecessor Theodore I Laskaris in [[1212]]. They had one son, the future [[Theodore II Doukas Laskaris]], but Eirene fell from a horse and was so badly injured that she was unable to have any more children. She retired to a convent, taking the monastic name Eugenia, and died there in [[1239]]. John III married as his second wife Constance (Anna) of Sicily, an illegitimate daughter of Emperor Frederick II by his mistress Bianca Lancia. They had no children.
