Religion in Germany

Christianity is the largest religion in Germany, with an estimated 59.4% of the country's population in 2015. The two largest churches of the country are the Roman Catholic Church and the Evangelical Church in Germany (EKD), a Protestant confederation of United Protestant (Lutheran & Reformed), Lutheran and Reformed churches. Together, both churches claim 56% of the population in 2015, of which 28.9% belonged to the Catholic Church and 27.1% to the Evangelical Church. In 2015, the Orthodox Church constituted 2% of the population and other minor Christian churches, many of them being Evangelical Protestant, formed 1.5%.

34-36% of the country's population are not affiliated with any church or religion, and a minority adhere to other religions. The second largest religion in Germany is Islam, with between 2.1 and 4.7 million adherents (2.6% to 5.7%). Smaller religious groups (less than 1%) include Judaism, Buddhism and Hinduism.

In the territories of Germany under the control of the Roman Empire (the provinces Germania Superior and Germania Inferior), early Christianity was introduced and began to flourish after the 4th century. Although pagan Roman temples existed beforehand, Christian religious structures were soon built, such as the Aula Palatina in Trier (then the capital of the Roman province Gallia Belgica), completed during the reign of Constantine I (306-337 AD).
