TheCatholic Church in Europe is part of the worldwideCatholic Church infull communion with theHoly See inRome, including representedEastern Catholicmissions. Demographically, Catholics are the largest religious group inEurope.

About 35%[1] of the population ofEurope today is Catholic, but only about a quarter of all Catholics worldwide reside in Europe. This is due in part to the movement and immigration at various times of largely Catholic European ethnic groups (such as theIrish,Italians,Poles,Portuguese, andSpaniards) to continents such as theAmericas andAustralia. Furthermore, Catholicism has been spread outside Europe through both historical Catholic missionary activity, especially inLatin America, and the past colonization and conversion of native people by Catholic European countries, specifically theSpanish,Portuguese,French andBelgian colonial empire, in regions such as South America,the Caribbean,Central Africa andWest Africa, andSoutheast Asia.[2]
As the Vatican State is atheocracy, it cannot become a member of the European Union. However, traditionally there are very strong ties of the Holy See with the only neighboring country of theVatican City,Italy and also with the European Union. Since 1970 the European Union accredits an official representative from the Holy See (an ApostolicNuncio) to the EU. Even though the Vatican City is not an official member of the European Union, it has adopted theEuro as its currency and has open borders with theSchengen Area.
