A model of an ionic crystal is constructed ab initio in terms of moving charged particles interacting mutually with an electromagnetic field. On the basis of the model the equations of motion of the crystal are derived by means of the Lagrangian formalism. Special attention is given to a precise description of interactions between polarizable ions and the electromagnetic field. Retardation of electromagnetic interactions as well as the existence of an external electromagnetic field are taken into account. The system of equations obtained seems to be convenient for an analysis of electromagneto‐optical processes in ionic crystals.
