Joachim from the kindred Türje (Hungarian:Türje nembeli Joachim, alsoIvachin orIwachin) was a Hungarian nobleman and soldier in the first half of the 13th century. He served as the first knownCount of Hermannstadt around 1210. Joachim was the forefather of the Szentgróti noble family.

Joachim was born into the illustriousgens Türje, which originated fromZala County. His father Gecse I, was the first known member of the kindred. He had at least three siblings: Denis I, the father of the powerful baronDenis II,Gecse II, who served asispán ofZala (1225) andBars counties (1236–1240).^[1] An unidentified sister was also mentioned in 1251, when she was widow of a deceased male member of thegens Ákos.^[2] Joachim had two sons from his unidentified wife:Thomas participated in theBattle of Mohi, and later functioned as theispán ofKarakó ispánate. The Szentgróti family descended from him. Joachim's younger son wasPhilip, an influential prelate in the second half of the 13th century, who served asBishop of Zagreb from 1247 or 1248 to 1262, and asArchbishop of Esztergom from 1262 until his death, and was a strong confidant of the Hungarian royal family.^[3] Joachim also had a daughter, who married Demetrius Zselizi.^[4]

Joachim was a faithful soldier ofAndrew II of Hungary. Around 1210, he served as the first known Count of Hermannstadt (or Szeben;Hungarian:szebeni ispán), and in this capacity, he was the head of theTransylvanian Saxons living in the wider region ofHermannstadt (now Sibiu in Romania).^[5] When an uprising broke out inVidin againstBoril of Bulgaria in that year, the Bulgarian ruler was unable to suppress the rebellion without external assistance and turned to Andrew II, reminding him "their reliable friendship". In response, the Hungarian king sent Joachim to lead an army of Saxons,Vlachs,Székelys andPechenegs across theCarpathian Mountains to fight forBoril of Bulgaria against three rebelliousCuman chieftains, according to a royal charter issued in 1250. The record suggests that the four ethnic groups were subjected to the Counts of Hermannstadt in the early 13th century. Joachim first routed the three Cuman chieftains who tried to halt his invasion, killing two of them in the battlefield, while the third one Karas was captured and sent to the Hungarian royal court as a prisoner. Following that Joachim's army marched along theDanube to Vidin, and besieged the castle. According to the 1250 charter, the Hungarian troops set fire to two gates of the fort and "fought valiantly". Joachim himself was gravely wounded in the skirmish, but Vidin was successfully captured and was given back to Boril, suppressing the rebellion against him.^[6] Joachim's four relatives were killed during the campaign. There is no consensus in historiography regarding the date of the uprising against Boril and Joachim's campaign, took place sometime between 1210 and 1214.^[7]

For his military service and merits, Joachim was granted lands inSlanje (today inCroatia) andVaraždin County. Four decades later,Béla IV of Hungary issued a royal charter inGyőr on 23 June 1250, which became the only source of information on Joachim's military campaign. In the document, the king confirmed Thomas and Philip, the sons of the late Joachim, in their inherited paternal land possessions, describing the merits of the three members of the Türje kindred.^[8] Joachim also participated in Andrew's military campaign against thePrincipality of Galicia in 1211.^[9] He acted as apristaldus (royal commissioner or "bailiff") in 1214, whencomes Nicholas was inducted into the ownership of the land ofLendva (present-day Lendava,Slovenia).^[10]
