Đakovo has existed as a city since the period of the Roman Empire called Certissia. Archaeological finds of graves dating from the 11th century onwards indicate the existence of life in these areas. The first written mention of Đakovo is the confirmation of Koloman's deed of donation from 1239. In 1252, a bishop's document was issued in Đakovo, written in a place called Đakovo. It is the first document written in Đakovo. The place was further developed and a castrum was built in it, inside which the cathedral and the court are located. There are few written historical sources about events in the Middle Ages, but one of the recorded is the Battle near Gorjani in which Queen Mary and her mother Elizabeth were abducted and their entourage was killed. The period that significantly marked the Middle Ages was the rule of the Turks. Christian buildings were replaced by mosques, bishops had no right to act. After the departure of the Turks, everything was returned to as it was before, and a new cathedral was built. Since the construction of that cathedral was weak, several bishops intended to build a new one. This idea was realized by Bishop Josip Juraj Strossmayer. The construction lasted from 1866 to 1882. St. Peter's Cathedral is one of the most important sacral buildings in Central Europe in the 19th century. Đakovo has nurtured the tradition of horse breeding since 1506, and the Đakovo stud farm has been visited by many celebrities, one of them being the Queen Elizabeth II. There are two museums in the city that keep exhibits in the ethnological, archaeological and historical collection. The most famous event that takes place in Đakovo is Đakovački vezovi, which has thousands of participants and visitors every year.
