The All-Russian nation or triune Russian nation, also called the pan-Russian nation, is the term for the Imperial Russian and later irredentist ideology that sees the Russian nation as comprising a "trinity" of sub-nations: Great Russia, Little Russia, and White Russia. Respectively, these sub-nations are contextually identified with Russians, Ukrainians, and Belarusians. Above all, the basis of the ideology's upholding of an inclusive Russian identity is centered around bringing all East Slavs under its fold.
