He is a poor village farmhand, but possesses remarkable slyness, wit and wile. He is often presented as the "typical Bulgarian" in Bulgaria and the "typical Macedonian" in North Macedonia. He is the perpetual antagonist of either the rich nobles, clerics and money lenders or the "typical Ottoman" — Nasreddin, whom he always manages to outwit. He is therefore regarded as a strictly positive figure and a hero of the common folk. According to a different folklore narratives he is either from Rousse area, according to another from Haskovo area, according to a third from Gabrovo area, according to a fourth from Prilep area, and so on, but in general, he is simply an imagined folk hero.
As a character, Hitar Petar first appeared in the 16th–17th century, when most of the Balkans were still under Ottoman rule. Tales on his deeds are present in the folklore of many regions. His name appeared for the first time in written records in the late 1850s. Petko Slaveikov wrote in 1858 about Hitar Petar. In 1862 Kuzman Shapkarev recorded from Metodi Kusev a long tale about Itar Petar. In 1869 Dobri Voynikov used his name as own nickname, and between 1870 and 1874 Dimitar Panichkov published the newspaper "Hitar Petar". Marko Cepenkov sent in 1870 to Petko Slaveykov a lot of proverbs about Itar Pejo. In 1873 Iliya Blaskov published in Rousse a small booklet with the anecdotes about Hitar Petar. Slaveykov, Vasil Cholakov and Dimitar Manchov also recorded folk tales about Hitar Peter at that time. His feats were adapted to an opera in 1967 and two comedy films, Nastradin Hodzha i Hitar Petar of 1939 and Hitar Petar of 1960.
There are many prose and poetry in which Itar Pejo appears as the main hero, and it was a common theme for Macedonian humor and cartoonists. In 1977, MRT recorded a TV series, according to the script by Mile Nedelkovski. There are over thirty stories about Itar Pejo, which firstly collected the writer Stale Popov in the collection "Itar Pejo". In 1966, Slavko Janevski published the poetry collection "The Gospel of Itar Pejo", which contains the songs "Itar Pejo for One Another" and "Svetovrazha".
Hitar Petar is similar to other characters of European and Oriental folklore, most notably Nasreddin of Islamic folklore, the German Till Eulenspiegel, the Flemish Thyl Ulenspiegel, the Hungarian Csalóka Péter and the Jewish Hershele Ostropoler.
