Finnish paganism in the context of "Water god"

Religion has been a major influence on the societies, cultures, traditions, philosophies, artistic expressions and laws within present-day Europe. The largest religion in Europe is Christianity. However, irreligion and practical secularisation are also prominent in some countries. In Southeastern Europe, three countries (Bosnia and Herzegovina, Kosovo and Albania) have Muslim majorities, with Christianity being the second-largest religion in those countries. Transcontinental nations between Europe and Asia also have muslim majorities, such as Turkiye and Azerbaijan, or large muslim minorities, such as Cyprus (including a de facto majority in the generally unrecognised Northern Cyprus) and Georgia.

Little is known about the prehistoric religion of Neolithic Europe. Bronze and Iron Age religion in Europe as elsewhere was predominantly polytheistic and included Ancient Greek religion, Ancient Roman religion, Slavic paganism, Finnish paganism, Celtic polytheism and Germanic paganism. Modern revival movements of these religions, and religions influenced by them, include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and Hetanism.

Modern Finnish paganism, also known as Finnish neopaganism or the Finnish native faith (Finnish: Suomenusko: "Finnish Belief / Belief of Finland"), is the contemporary revival of Finnish paganism, the pre-Christian polytheistic ethnic religion of the Finns. A precursor movement was the Ukonusko ("Ukko's Faith", revolving around the god Ukko) of the early 20th century. The main problem in the revival of Finnish paganism is the nature of pre-Christian Finnish culture, which relied on oral tradition which may be subject to change over time. The primary sources concerning Finnish native culture are written by latter-era Christians.

There are two main organisations of the religion, the "Association of Finnish Native Religion" (Suomalaisen kansanuskon yhdistys ry) based in Helsinki and officially registered since 2002, and the "Pole Star Association" (Taivaannaula ry) headquartered in Turku with branches in many cities, founded and officially registered in 2007. The Association of Finnish Native Religion also caters to Karelians and is a member of the Uralic Communion.

Tietäjä (Finnish pronunciation: [ˈtie̯tæjæ], pl. tietäjät, 'seer', 'wise man', literally 'knower') is a magically powerful figure in traditional Finnic culture, whose supernatural powers arise from his great knowledge.

Finnish mythology commonly refers to the folklore of Finnish paganism, of which a modern revival is practiced by a small percentage of the Finnish people. It has many shared features with Estonian and other Finnic mythologies, but also with neighbouring Baltic, Slavic and, to a lesser extent, Norse mythologies.

Finnish mythology survived within an oral tradition of mythical poem-singing and folklore well into the 19th century.
