One of the things done was the eradication of Roman Catholic practices, including stained glass and statues (royal.gov.uk). There came about the Act of Uniformity, which required the use of the first Book of Common Prayer. .
This whole movement and especially the Act increased contention between Roman Catholics and those who followed that of the Protestant movement (infoplease.com). From this an unsuccessful rebellion occurred in the west. The first actual conflict that turned into battle was when the Scots who promised to betroth Mary, Queen of Scots, to Edward broke the promise they made for Mary to marry Edward. To think after all that Henry VIII went through and his son and heir (being so sickly) may now not be able to reproduce (since he has no wife) and carry on the Tudor name. This caused Seymour, Edward's uncle and Protector, to lead a punitive expedition against the Scots. Seymour being a very able soldier led England to their victory at the Battle of Pinkie Cleugh in 1547. The battle was never followed up with satisfactory peace terms though (royal.gov.uk). .
After this battle and how it was resolved the Scots strengthened their alliance with France. At the time France was one of the biggest threats to England. Then, in 1549 war broke out between England and France over the procession of Boulogne. While all this was going on there arose a pressing agrarian problem of enclosure of common lands (infoplease.com). During this Edward Seymour stood up for the peasants to try to prevent enclosure. This is where the Protectorship switched over to John Dudley, duke of Northumberland, he saw that the wealthy landowners were more influential in the situation and went with them. Then, down the road Seymour was executed in the Tower of London in 1552. .
John Dudley becoming Protector seemed to be a fairly good turn for England. There was the prorogation of Parliament in 1550 and the expulsion of Catholics from the council.
