The religion/pantheon of the Baltic people stems from Baltic paganism and continues after Christianization and into Baltic folklore. The Baltic region was one of the last regions of Europe to be Christianized, a process that began in the 15th century and continued for at least a century afterward. While no native texts survive detailing the mythology of the Baltic peoples during the pagan period, knowledge of such beliefs may be gained from Russian and German chronicles, later folklore, etymology, and the reconstructions of comparative mythology.
Hailing from Lithuania, Latvia, and Estonia and historically dominated by Germanic tribes, the Baltic people's early folklore was inspired by their own cultures and that of their neighbors. However, it was not until the 17th century that Baltic mythology began to form something recognizable as distinct from its sources. While no contemporary texts detail the folklore of the Baltic peoples during the pagan period, knowledge of such belief can be gleaned from Russian and German chronicles, more recent mythology, and even from etymology
