Which dissenter of the government was publicly executed?

One of the most notable dissenters publicly executed was Thomas More, an English lawyer and statesman. He was executed in 1535 for refusing to accept King Henry VIII's authority as the head of the Church of England and for opposing the king's divorce from Catherine of Aragon. More's steadfast adherence to his Catholic faith and refusal to compromise his principles ultimately led to his martyrdom. His execution is often seen as a significant moment in the struggle between individual conscience and state power.
