The history of Europe was deeply influenced by the spread of Christianity during the Middle Ages.
Scholars often examine how Christianity adapted to local customs as it spread across different continents, resulting in a diverse array of liturgical practices and cultural expressions.
From Middle English Cristiente, Cristente, borrowed from Old French crestienté, from Medieval Latin stem of Chrīstiānitās, from Latin christianus, Christianus, from Ancient Greek Χριστιανός (Khristianós), from Χριστός (Khristós, “Christ, anointed one”) + Latin -anus (“suffix for of, related to”) + one more suffix borrowed from Latin "ity" makes the final Christian + -ity. The term was respelled in the early modern English period to more closely reflect its Latin etymon.
Usually uncountable when referring to the faith; can be used with an article when referring to a specific historical or regional form.
