There are many small historic Slavic nations like Lusatia (and Lusatian Serbs, typically referred to as Sorbs, who still live in eastern Germany), Rusyn, Kashubia and others. Russia is now the most powerful and populated Slavic country, but in the 10th century Serbs and Czechs were powerful, in 13th and 14th century Serbs were powerful, and in the 16th century Poland was the strongest nation in the area.
