The functions of the state in historical development are investigated. It is proved that the main functions fall into the changes that take place in the state; the derivative functions fall under the more powerful influence of the established ethnocultural strata of societ’ys life, national, territorial peculiarities, traditions, etc, and therefore the state of the modern type, which appears in the results of the development of a specific state-organized society, can, in explicit or hidden forms, be preserved andsometimes to develop some traditional functions of the state. In the context of the theory of state and law, the functions of the state are analyzed and shown that they are not a stable and unalterable phenomenon, fundamental and frozen in its development, and depending on the specific historical conditions, the elements of these general functions may acquire independent significance and signs of independence.
The state-legal phenomena and processes in conceptual positions of the theory of state and law with the use of methods of classification of state functions for their further ordering and comparison are investigated. It is shown that their classification is important for understanding the functions of the state, which allows not only to reveal common features but also to formulate a scientifically
grounded opinion about the variety of functions of the state.
It is proved that due to the classification of state functions, it is possible to work out practical recommendations regarding the main directions of state activity not generalized and declaratively, but differentiated with respect to each separate function.
It is highlighted that the classification criteria of state functions allow enumeration of different functions of the state to a particular class and group. The most common groups of state functions are classified: 1) their division into external functions and internal functions;
2) according to the criterion of importance for the state, the main and derivative (additional, or non-principal) functions of the state are distinguished; 3) in the time duration of the existence of the functions of the state distinguish between mandatory (permanent, continuous) and temporary (non-permanent, transitory); 4) depending on the social interests of which the functions of the state are performed,
they are divided into general social groups and groups (for the protection of the interests of a certain stratum of society); 5) sectoral division of functions of the state, that is, the division of the social sphere (economic, social, law enforcement, environmental, etc.).
