Latvian mythology is the collection of myths that have emerged throughout the history of Latvia, sometimes being elaborated upon by successive generations, and at other times being rejected and replaced by other explanatory narratives. These myths stem from folk traditions of the Latvian people and pre-Christian Baltic mythology.
Latvian mythology is used particularly as a tool for reconstructing and analysing the historical pagan beliefs and national identity of Latvia.
It is important to note that the minute details of most, if not all of these myths vary per region and sometimes even family.
There are few reports of Baltic tribes, the ancestors of modern Latvians, and their mythology until Christianization in the 13th century. Since Christianization, there have been several reports related to local mythology including chronicles, travel reports, visitation records, Jesuit reports and other accounts of pagan practices. These reports are considered secondary sources by researchers because since the authors were not Latvian, they did not speak the local languages and often were biased. These materials are sometimes imprecise and contain errors, fabrications, and distortions stemming from a Christian world view. Despite this, they can often be verified using information from folklore.
Most folklore materials have been collected since the mid-19th century. In the 18th and 19th centuries, it was assumed that Baltic tribes were originally one nation and thus had the same deities. Early authors tried to reconstruct a Latvian pantheon using data from neighboring regions. This trend was later also adopted by Latvian national romanticists. After the abolition of serfdom, a new national identity was forming and authors sought to prove that Baltic cultural traditions were as deep as those of other nations. It was hoped that a grand epic could be constructed using pieces preserved in folklore. It was also thought that the ancient religion, forgotten during 700 years of oppression, could be reconstructed.
