Slavs
Slavs can be further grouped by religion. Orthodox Christianity is practiced by the majority of Slavs. The Orthodox Slavs include the Belarusians, Bulgarians, Macedonians, Montenegrins, Russians, Serbs, and Ukrainians and are defined by Orthodox customs and Cyrillic script as well as their cultural connection to the Byzantine Empire (Serbs also use Latin script on equal terms). Their second most common religion is Roman Catholicism. The Catholic Slavs include Croats, Czechs, Kashubs, Moravians, Poles, Silesians, Slovaks, Slovenes, and Sorbs and are defined by their Latinate influence and heritage and connection to Western Europe. There are also substantial Protestant and Lutheran minorities especially amongst the West Slavs, such as the historical Bohemian (Czech) Hussites.
Modern history of Ukraine
Ukraine emerges as the concept of a nation, and the Ukrainians as a nationality, with the Ukrainian National Revival which is believed started sometime at the end of 18th and the beginning of 19th century. According to Ukrainian historian Yaroslav Hrytsak, the first wave of national revival is traditionally connected with publication of the first part of "Eneyida" by Ivan Kotlyarevsky (1798). In 1846 in Moscow was published "Istoriya Rusov ili Maloi Rossii" (History of Ruthenians or Little Russia). During the Spring of Nations, in 1848 in Lemberg (Lviv) was created Supreme Ruthenian Council which declared that Galician Ruthenians are part of bigger Ukrainian nation. The council adopted the yellow and blue flag (Flag of Ukraine).
