Henry Breaks with Pope; Persecutions Continue
On March 26, 1534, the English Parliament renounced all dependence upon the “Court of Rome.” The long expected break with the pope was finally made, though King Henry VIII never turned from Catholic doctrine. After this, the persecutions continued and even increased, but they changed character somewhat. Before the watchword was heresy. Now it was treason. Before the trouble was mainly poured out upon Bible believing Christians and possessors of the English Scriptures. Now it was poured out upon anyone, whether Protestant or Catholic or whatever, who opposed Henry’s actions.

The English sovereigns always fought to maintain the rights of Kings vs. the claims of the Popes to have the power to appoint leaders and investiture in the church. The church of Rome was after all more of a political organ than religious during the dark ages. The power it wielded was the fear of excommunication and it's spurious claims to control and individual's salvation. I'm sure this is a major factor in not wanting Bibles produced in the vernacular.
