Lutheranism is one of the largest branches of Protestantism, identifying with the theology of Martin Luther, a 16th-century German monk and reformer whose efforts to reform the theology and practice of the Roman Catholic Church launched the Protestant Reformation. The reaction of the government and church authorities to the international spread of his writings, beginning with the Ninety-five Theses, divided Western Christianity.[1] During the Reformation, Lutheranism became the state religion of numerous states of northern Europe, especially in northern Germany, Scandinavia and the then Livonian Order. Lutheran clergy became civil servants and the Lutheran churches became part of the state.
