Sir Thomas More (7 February 1478 - 6 July 1535), also known by Catholics as Saint Thomas More, was an English lawyer, social philosopher, author, statesman and noted Renaissance humanist. He was an important councillor to Henry VIII of England and, for three years toward the end of his life, Lord Chancellor. He is recognised as a saint within the Catholic Church and is commemorated by the Church of England as a "Reformation martyr".[2] He was an opponent of the Protestant Reformation and in particular of Martin Luther and William Tyndale.

More coined the word "utopia" -- a name he gave to the ideal, imaginary island nation whose political system he described in Utopia, published in 1516. He opposed the king's separation from the Catholic Church and refused to accept the king as Supreme Head of the Church of England, a status the king had been given by a compliant parliament through the Act of Supremacy of 1534. He was imprisoned in 1534 for his refusal to take the oath required by the First Succession Act, because the act disparaged the power of the Pope and Henry’s marriage to Catherine of Aragon. In 1535, he was tried for treason, convicted on perjured testimony, and beheaded.

Intellectuals and statesmen across Europe were stunned by More's execution. Erasmus saluted him as one "whose soul was more pure than any snow." Two centuries later Jonathan Swift said he was "the person of the greatest virtue this kingdom ever produced", a sentiment with which Samuel Johnson agreed. Historian Hugh Trevor-Roper said in 1977 that More was "the first great Englishman whom we feel that we know, the most saintly of humanists, the most human of saints, the universal man of our cool northern renaissance."[3] The Catholic Church proclaimed him a saint in 1935.
