Religion in Ukraine
Religion in Ukraine is diverse, with a majority of the population adhering to Christianity. A 2018 survey conducted by the Razumkov Centre found that 71.7% of the population declared themselves believers. About 67.3% of the population declared adherence to one or another strand of Orthodox Christianity (28.7% of the Kiev Patriarchate, 23.4% state simply 'Orthodox' with no declaration as to which Patriarchate they belong to, 12.8% of the Moscow Patriarchate, 0.3% Ukrainian Autocephalous Orthodox Church, and 1.9% other types of Orthodoxy), 7.7% 'Christian' with no declared denominational affiliation, 9.4% Ukrainian Byzantine Rite Catholics, 2.2% Protestants and 0.8% Latin Rite Catholics. Judaism was the religion of the 0.4%; while Buddhism, Paganism (Rodnovery), and Hinduism were each the religions of 0.1% of the population. A further 11.0% declared themselves non-religious or unaffiliated. According to the surveys conducted by Razumkov in the 2000s and early 2010s, such proportions have remained relatively constant throughout the last decade, while the proportion of believers overall has decreased from 76% in 2014 to 70% in 2016 and 72% in 2018.

History of Christianity in Ukraine
In the Union of Brest of 1596 (colloquially known as "unia"), a part of the Ukrainian Church was accepted under the jurisdiction of the Roman Pope, becoming a Byzantine Rite Catholic Church, a Ukrainian Greek Catholic Church, colloquially known as the Uniate Church. While the new church gained many faithful among the Ukrainians in Galicia, the majority of Ukrainians in the rest of the lands remained within Eastern Orthodoxy with the church affairs ruled by then from Kiev under the metropolitan Peter Mogila "(Petro Mogyla)". The Orthodox Church was made illegal (its legality was partially restored in 1607), its property confiscated, and Orthodox believers faced persecution and discrimination which became an important reason for large numbers of Ukrainians to emigrate to Tsardom of Russia following the Union. The eastward spread of the Union of Brest led to violent clashes, for example, assassination of the Greek Catholic Archbishop Josaphat Kuntsevych by the Orthodox mob in Vitebsk in 1623.
