What do you mean by "Puritans"?
Various forms of conservative Protestantism took root in some major European Countries. Switzerland and the teachings of John Calvin (1509-1564) comes to mind. Germany less conservative via Martin Luther,(1483-1546) perhaps the father of the Protestant reformation.
People here have mentioned the Mennonites. Some groups of people with the same theological base are called "Amish". They are all a versions of Anabaptists, (1527) as far as I can tell.
In "The Protestant Ethic And The Spirit of Capitalism" Max Weber argues that Calvinist predeterminism is the theological/moral base of capitalist

"Anabaptism (from
Neo-Latin anabaptista,
[1] from the
Greek ἀναβαπτισμός: ἀνά- 're-' and βαπτισμός '
baptism',
[1] German:
Täufer, earlier also
Wiedertäufer)
[a] is a
Protestant Christian movement which traces its origins to the
Radical Reformation.
The early Anabaptists formulated their beliefs in a
confession of faith called the
Schleitheim Confession. In 1527,
Michael Sattler presided over a meeting at
Schleitheim (in the
Canton of Schaffhausen, on the Swiss-German border), where Anabaptist leaders drew up the Schleitheim Confession of Faith (doc. 29). Sattler was arrested and executed soon afterwards. Anabaptist groups varied widely in their specific beliefs, but the Schleitheim Confession represents foundational Anabaptist beliefs as well as any single document can.

Calvinism (also called the
Reformed Tradition,
Reformed Protestantism,
Reformed Christianity or simply
Reformed[1]) is a major branch of
Protestantism that follows the
theological tradition and forms of
Christian practice set down by
John Calvin and other
Reformation-era theologians. It emphasises the
sovereignty of God and the
authority of the
Bible.
Calvinists broke from the
Roman Catholic Church in the 16th century. Calvinists differ from
Lutherans (another major branch of the Reformation) on the
spiritual real presence of Christ in the Lord's Supper,
theories of worship, the purpose and meaning of baptism, and the
use of God's law for believers, among other points.
[2][3] The label
Calvinism can be misleading, because the religious tradition it denotes has always been diverse, with a wide range of influences rather than a single founder; however, almost all of them drew heavily from the writings of
Augustine of Hippo twelve hundred years prior to the Reformation.
