In the 16th century, Protestantism began spreading rapidly in Lithuania. The first wave of Protestantism was Lutheranism that reached Lithuania throughPrussia; the second wave was Calvinism that mostly spread throughPoland. This was because many Lithuanians had a relatively poor understanding of Catholic beliefs as there were few Lithuanian-speaking priests at the time. In addition, many sons of influential Lithuanian nobles would study abroad in Germany where they would learn about the ideas ofReformation. When they returned home, they would oftentimes use theirright of patronageto confiscate Catholic churches and give them to pastors, convert their serfs either to Lutheranism or Calvinism. In 1536, the prevalence of Protestantism grew even more asRadziwiłł, Billewicz,Chodkiewiczfamilies left theRoman Catholic Church. However, Protestantism inLithuania Propereventually lost ground as it failed to secure the support from the local clergymen and were at odds with one another, which weakened their positions in the country. There were also religious persecutions, which caused many Lithuanian pastors to flee to Lithuania Minor. Despite this, Protestantism remained to have a strong presence in Lithuania Proper until the late 17th century.

According to Losch (1932), the Lutherans were 3.3% of the total population; they were mainlyGermansin theMemel territory(now Klaipėda). There was also a tiny Reformed community (0.5%)which still persists. Protestantism has declined with theremoval of the GermanandPrussian Lithuanianpopulations, and today it is mainly represented by ethnic Lithuanians throughout the northern and western parts of the country, as well as large urban areas. Believers and clergy suffered greatly during the Soviet occupation, with many killed, tortured or deported to Siberia. Newly arrivingevangelical churcheshave established missions in Lithuania since 1990.
Protestantsmake up 0.8% of the population,with 0.56% belonging to theEvangelical Lutheran Church of Lithuania.
Lutheranism in Lithuania dates back to the 16th century, when it came mainly from the neighbouring German-controlled areas ofLivoniaandEast Prussia. A Synod in Vilnius united the church in 1557. The parish network covered nearly all of the Grand Duchy, with district centers in Vilnius, Kedainai, Biržai, Slucke, Kojdanove and Zabludove later Izabeline. Small Protestant communities are dispersed throughout the northern and western parts of the country.
The majority ofPrussian Lithuaniansliving in East Prussia and in Memelland (since 1945 theKlaipėda Regionof Lithuania) belonged to theEvangelical Church of the old-Prussian Union. Most resettled in theWest GermanyafterWorld War IIalong with theethnic Germaninhabitants.
Since 1945, Lutheranism in Lithuania has declined largely due to the ongoing secularization that sweeps throughout Europe.
