What was the most significant result of Martin luthers attempt to reform the Catholic Church

The creation of protestantism and the split of the catholic church.

Explanation:

The Protestant Reformation was the 16th-century religious, political, intellectual and cultural upheaval that splintered Catholic Europe, setting in place the structures and beliefs that would define the continent in the modern era. Basically in europe pre- martin luther, politics had been dominated by the Catholic church, and Martin Luther wrote a docturne called the 95 thesis that challenged it's authority. All of this caused a schism in the Catholic Church, catalysed by the Edict of Worms which extradized Martin Luther.

Basically undermined the political dominance of papal authority, especially in the Holy Roman Empire, leading to many wars of religion and contributed heavily to the split of the Holy Roman Empire.
