There were at least two well-known Americans who espoused voluntaryist causes during the mid-19th century. Henry David Thoreau's first brush with the law in his home state of Massachusetts came in 1838, when he turned twenty-one. The state demanded that he pay the one dollar ministerial tax in support of a clergyman, "whose preaching my father attended but never I myself". When Thoreau refused to pay the tax, it was probably paid by one of his aunts. In order to avoid the ministerial tax in the future, Thoreau had to sign an affidavit attesting he was not a member of the church.
