I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Without Luther's backing for the uprising, many rebels laid down their weapons; others felt betrayed. Their defeat by the Swabian League at the Battle of Frankenhausen on 15 May 1525, followed by Müntzer's execution, brought the revolutionary stage of the Reformation to a close. Thereafter, radicalism found a refuge in the anabaptist movement and other religious movements, while Luther's Reformation flourished under the wing of the secular powers."? 

Why did the revolution end?
