Donskoya (The Green North)

The Socialist Republic of Donskoya (Russian: --); also known as Donskoya, Socialist Republic, and abbreviated as the S.R.D, is a nation located on the border of Greenland and North America.

Etymology
The name Donskoya is derived from Dmitry Donskoy because he was the first to openly challenged Mongol authority in Russia. They first had to live with Russian, then Soviet authority but have always resisted the Soviets and the Romanovans trying to take control of all their lands. (and would follow a similar course that Dmitry faced, thus the reason for the name.)
