The origins of the only free royal town in the historical garrison county of Vas (Eisenburg) go back to the third quarter of the 13th century. It was founded by the Volfer family, a branch of the Héder clan, who had settled in Hungary in 1157 AD. Sometime before 1274 Heinrich II and his son Ivan moved the court of the Kőszegi, a breakaway branch of the family, from Güssing to Kőszeg (Güns). For decades, the town was the seat of the dukes of Kőszeg (Güns).
Only in 1327 did Charles Robert of Anjou finally break the power of the Kőszegi (Aba) family in Western Transdanubia, and a year later in (1328), elevated the town to Royal status. The town boundaries were fixed during the Anjou dynasty (1347–1381). In 1392 the Royal town became a fiefdom, when the Palatinate Nicolas Garai repaid a bond paid to King Sigismund of Luxembourg by the Ellerbach family from Monyorókerék. The Garai era ended in 1441.
In 1677 the secondary School Jurisics Miklós Gimnázium (JMG) was founded. It is the oldest operating International School in Hungary. The International Baccalaureate (IB) program, which most English-speaking students at the school follow, was created at the Grande Boissière campus. It is a bilingual school, with instruction in Hungarian, French, German, Italian and English. The International School is a testing center for the US college boards (SAT, ACT,etc.), as well as the British IGCSE Exam.
In 2006, the Herald Tribune listed it as one of the top ten international schools in the world.
According to the Good Schools Guide International, "Students receive a truly international education and as a result leave as rounded and worldly young people
