Lithuania

The oldest of the Baltic Brothers, Lithuania is a rather gentle-hearted person, but worries constantly. His best friend is Poland, who affectionately calls him “Liet” (derived from "Lietuva," the Lithuanian word for "Lithuania"). During medieval times, they combined and created the Polish-Lithuanian Commonwealth. They conquered more than half of Europe and had complete control over middle Europe. Eventually, Russia split them up when he created the Soviet Union, but they’re still good friends nowadays, and were said to have attended rehab together (because of the trauma they endured due to Russia).
