What role did the Diet of Speyer in 1526 play in the Reformation in Hesse?

The Diet of Speyer in 1526 played a pivotal role in the Reformation in Hesse by providing the necessary legal framework for Philip, Landgrave of Hesse, to formally implement religious reforms in his territory.

During the 1526 diet, the imperial authorities, needing military support against external threats, postponed the implementation of the 1521 Edict of Worms. The diet issued a decree stating that each estate could act, live, and govern in religious matters in a way that they could justify before God and the Emperor. Philip interpreted this as a legal basis to proceed with the Reformation in Hesse. Following this decree, and after discussions at a synod in Homberg, Philip moved forward with establishing a state church, eventually adopting a model similar to that of the electorate of Saxony.
