Answer:
Promise to write a new constitution.
Explanation:
Fredrick William Fourth who ruled Prussia in 1848 was a very strong ruler. Fearing the threat of revolution which has engulfed most of Europe in that time he prepared to suppress the rebellion but he also promised to write a new constitution. He took a liberal stand because he knew that a staunch stand could lead to revolution which he did not want to confront.
