The Norwegian Lutheran Church in the United States is a general term to describe the Lutheran church tradition developed within the United States by immigrants from Norway.
Most Norwegian immigrants to the United States, particularly in the migration wave between the 1860s and early 20th century, were members of the Church of Norway, an evangelical Lutheran church established by the Constitution of Norway. As they settled in their new homeland and forged their own communities, however, Norwegian-American Lutherans diverged from the state church in many ways, forming synods and conferences that ultimately contributed to the present Lutheran establishment in the United States.
The first organized emigrants from Norway to the United States were religious dissenters on the Restauration during 1825. It is widely considered that many of them had Quaker sympathies, but it is also clear that many were Haugeans, adherents of the lay preacher Hans Nielsen Hauge, who was a devout Lutheran but at odds with the established Norwegian State Church. Many of these emigrants subsequently relocated to the Fox River Settlement in LaSalle County, Illinois. By most accounts, the first minister at Fox River was a layman by the name of Ole Olsen Hetletvedt (1797– 1854), a Haugean in leaning. He was one of the early Norwegian settlers who had crossed the Atlantic Ocean in 1825 on board the Restauration.
In 1839, Elling Eielsen, a lay preacher, was a leader in the Haugean pietistic state church reform movement which encouraged evangelism and vigorous lay leadership. He made it his mission to return the growing Fox River Norwegian colony to the Lutheran fold. He organized a house of assembly and was ordained a Lutheran pastor in 1843 in the German-Lutheran tradition. Evangelical Lutheran Church in America, known as the Eielsen Synod, founded in 1846 at the Jefferson Prairie Settlement, was named in his honor. Eislsen was resident pastor at Jefferson Prairie from 1846 to 1872.
