Abstract
The article is dedicated to the study of the Gaius Julius Caesar’s contribution to the development of roman agricultural law. The statute of the founded iussu Cesarius colony Genetiva Iulia was used as a main source. The author considers the Caesar's legislative innovations, touching surveying net and usage of the common lands. The regulations protecting public roads (we find limites among them) are typical for the roman agricultural legislation. Nevertheless, lex coloniae Genetivae Iuliae contains a fundamental innovation, because it touches categories of colony's lands. We find in the statute not only different kinds of lands - agri and silvae , but also an attempt of regulation of their usage. However, the categories of the common lands of colonies were finally designed only in the Augustus’ legislation.
