югосла́вия

Even if your native language doesn't have a plural for proper nouns like Yugoslavia, Russian often uses the plural here too, e.g. in enumerations. Example sentence: За перестройками, Чечнями, кризисами, Югославиями образ Шукшина теряется. After perestroika, Chechnya, crises, Yugoslavia, Shukshin's view of the world is lost. Sandy
