Who was the Protestant leader who came to be very important and influential after 1550.

Protestantism originated from the Protestation at Speyer in 1529, where the nobility protested against enforcement of the Edict of Worms which subjected advocates of Lutheranism to forfeiture of all of their property.[1] However, the theological underpinnings go back much further, as Protestant theologians of the time cited both Church Fathers and the Apostles to justify their choices and formulations. The earliest origin of Protestantism is controversial; with some Protestants today claiming origin back to groups in the early church deemed heretical such as the Montanists.

Since the 16th century, major factors affecting Protestantism have been the Catholic Counter-Reformation which opposed it successfully especially in France, Spain and Italy. Then came an era of confessionalization followed by Rationalism, Pietism, and the Great Awakenings. Major movements today include Evangelicalism, mainline denominations, and Pentecostalism.
