Thomas Helwys (c. 1575 — c. 1616), an Englishman, was one of the joint founders, with John Smyth of the Baptist denomination.
In the early seventeenth century, Helwys was principal formulator of that distinctively Baptist request: that the church and the state be kept separate in matters of law, so that individuals might have a freedom of religious conscience. Thomas Helwys was an advocate of religious liberty at a time when to hold to such views could be dangerous. He died in prison as a consequence of the religious persecution of Protestant dissenters under King James I.
