John III Doukas Vatatzes, Latinized as Ducas Vatatzes (Greek: Ιωάννης Γ΄ Δούκας Βατάτζης, Iōannēs III Doukas Vatatzēs, c. 1192, Didymoteicho – 3 November 1254, Nymphaion) was emperor of Nicaea 1221–1254.

John Doukas Vatatzes was probably the son of the general Basileios Vatatzes, Duke of Thrace, who died in 1193, and his wife, an unnamed daughter of Isaakios Angelos and cousin of the Emperors Isaac II Angelos and Alexios III Angelos. The Vatatzes family had first become prominent in Byzantine society in the Komnenian period and had forged early imperial connections when Theodore Vatatzes married the porphyrogenete princess Eudokia Komnene, daughter of Emperor John II Komnenos. John Doukas Vatatzes had two older brothers. The eldest was Isaakios Doukas Vatatzes (died 1261), who married and had two children: Ioannes Vatatzes (born 1215), who married to Eudokia Angelina and had two daughters Theodora Doukaina Vatatzaina, wife of Michael VIII Palaiologos, and Maria Vatatzaina, married to Michael Doukas Glabas Tarchaneiotes, Military Goveror of Thrace; and a daughter, married to Konstantinos Strategopoulos. His other older brother was the father in law of Alexios Raul (died 1258).[1]
A successful soldier from a military family, in 1212, John was chosen by Emperor Theodore I Laskaris as husband for his daughter Irene 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,[2] 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.[3]
John III's possession of Adrianople was terminated by Theodore Komnenos Doukas of 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 Elena of Bulgaria and Theodore II, respectively 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.[4] 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.[5] 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 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 and annexed the important island of Rhodes.[6]
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. A half-century after his death, John III was canonized as a saint, under the name John the Merciful and was still commemorated annually until recent times.[7]
John III Doukas Vatatzes married first Irene Lascarina, the daughter of his predecessor Theodore I Laskaris in 1212. They had one son, the future Theodore II Doukas Laskaris, but Irene 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 II of Hohenstaufen, an illegitimate daughter of Emperor Frederick II by his mistress Bianca Lancia. They had no children.
