What movement started the Protestant Reformation? How/Why?

In England, the Reformation began with Henry VIII's quest for a male heir. When Pope Clement VII refused to annul Henry's marriage to Catherine of Aragon so he could remarry, the English king declared in 1534 that he alone should be the final authority in matters relating to the English church.

Explanation:

Although the Reformation is usually considered to have started with the publication of the Ninety-five Theses by Martin Luther in 1517, there was no schism between the Catholic Church and the nascent Luther until the 1521 Edict of Worms.
