Baltic religion

Baltic religion is the pre-Christian religion of the Baltic-speaking peoples of what are now Latvia and Lithuania, and of the Old Prussians, absorbed into German-speaking lands as their language died out. Direct evidence is scarce and late, drawn mainly from foreign chroniclers, archaeology, and a large body of folk songs, or dainas, recorded mainly in the nineteenth and twentieth centuries; even so, Baltic religious vocabulary preserves features shared with ancient Indian Vedic religion, including a sky god, Dievs, related to Dyaus and to the Greek Zeus. Germany's Teutonic Order conquered Baltic lands in the thirteenth and fourteenth centuries, but Lithuania's grand dukes kept their native religion until Jogaila, baptized in 1386, formally introduced Christianity to his subjects the following year.^{[1–3, 5–6]}

A late-documented religion to 13th century CE

The Balts' religion is known mainly through archaeology, a handful of medieval foreign chronicles, and folklore recorded centuries later, since no native Baltic religious texts survive; Germany's Teutonic Order and allied crusading orders conquered the Baltic lands in the thirteenth and fourteenth centuries but made little further effort at religious conversion once in control, which, paradoxically, helped preserve older beliefs and customs for longer.^{[2, 6]}

The sky gods and the farmer's year reconstructed, pre-13th century

At the center of Baltic religion stood Dievs (Lithuanian Dievas, Old Prussian Deivas), a sky god etymologically related to the ancient Indian Dyaus and the Greek Zeus, beside Pērkons (Lithuanian Perkūnas), the Thunderer, a warrior and fertility god who controlled rain and received sacrifices in drought, sickness or plague, and Saule, the sun, uniquely female in Baltic tradition and honored above all at the summer solstice with song, dance and a ritual meal.^[3–4]

Christianization and survival in folklore 13th–20th century CE

The Old Prussians were conquered and gradually assimilated by German settlers, their language and religion dying out, while Lithuania's rulers kept their native religion into the late fourteenth century: Grand Duke Jogaila was baptized in 1386 and, the following year, formally introduced Roman Christianity among his Lithuanian-speaking subjects, after which Baltic folk songs, or dainas, continued to carry older religious imagery for generations.^{[2, 5]}

How we know

Reconstructing a religion from song and silence

Baltic religion left no native texts of its own; what is known comes from three kinds of evidence: archaeology, which has revealed burial and sacrificial remains but no clear sign of named gods or organized cult; a small number of foreign, mostly German-authored chronicles, written by conquerors who neither spoke the Baltic languages nor had much interest in the religion's own terms; and dainas, short folk songs, recorded in large numbers only from the nineteenth century, which are unusually rich in preserved pre-Christian imagery because the region's conquerors made little attempt at religious conversion after their military victory.^{[2, 6]}

Common misconceptions

Myth Baltic religion is a living, continuously practiced faith today in the same form as before Christianization.

Fact The pre-Christian religion described here is reconstructed mainly from archaeology, foreign chronicles and later folklore; the modern Romuva movement in Lithuania and related groups in Latvia are twentieth-century revivals that draw on this older material but are a separate, modern phenomenon rather than an unbroken continuation of it.^[2]
