• Martin Luther was very  upset with the church's wealth.
• Martin Luther Did not a agree with the church selling Indulgences which was a certificate that said it would reduce your punishment for your sins after you died.
• Luther wrote 'the ninety five these' and nailed it to the church door.which was Luther's protestant translation of the bible.That idea was spread through German, and that led to a new church called the 'Lutheran church'.
