The aim of this paper is to provide insight into the day to day activities of the inhabitants of the medieval communes of Kastav, Veprinac and Mošćenice. By using the only remaining sources, the communal statutes, the paper will try to recreate the government organization of the communes, as well as how the statutory regulations shaped everyday life. With analysing these neighbouring medieval communes the paper will try to point out the similarities and differences of the three communal statutes, from the composition of the texts, to the subject of their articles. By researching these statutes the main focus of the paper will be to show their impact on the population.
