The coat of arms of the Russian Federation derives from the earlier coat of arms of the Russian Empire, as restored in 1993 after the constitutional crisis. Though modified more than once since the reign of Ivan III (1462–1505), the current coat of arms is directly derived from its mediaeval original. The general chromatic layout corresponds to the early fifteenth century standard[citation needed]. The shape of the eagle can be traced back to the reign of Peter the Great (1682–1725), although the eagle charge on the present coat of arms is golden rather than the traditional, imperial black.(wikipedia)
