 # Hamiltonian formalism of mechanics
 
-The Hamiltonian formalism of mechanics is based on the definitions posed by [Lagrangian mechanics](/en/physics/mechanics/lagrangian-mechanics/lagrangian-formalism) and the axioms, postulates and principles posed in the [Newtonian formalism](/en/physics/mechanics/newtonian-mechanics/newtonian-formalism/).

 In Hamilton's formulation the stationary action principle is referred to as Hamilton's principle.
