What probably contributed most to the spread of Martin Luther's ideas?

Answer 1

Luther wrote many essays and books which were published and subsequently distributed throughout Europe. The printing press allowed for the massive replication of his writings (his most renowned being the Ninety-Five Theses). Many Europeans wanted to break away from the established forms of religion due to corruption and, therefore, were intrigued by Luther's new ideas and philosophies. People throughout Europe read his works and converted to Protestantism.

When an edict of the Diet called for Luther's seizure, his friends took him for safekeeping to Wartburg, the castle of Elector Frederick III of Saxony. Here, Luther continued to write his prolific theological works, which greatly influenced the direction of the Protestant Reformation movement. It was here that Luther translated the New Testament into German. This was published on 21 September 1522. Luther also began translating the entire Bible, which took him 10 years to complete. Luther's extensive writing on church matters included the composition of hymns, liturgy, and two catechisms that are basic statements of the Lutheran church.
