Due to Luther's comprehensive and systematic exposition of compulsory education thought, coupled with the religious reform movement and his great influence, his thoughts have been widely spread in many countries in Europe and America, and he has become the earliest theoretical pioneer of modern western national education movement and universal compulsory education movement. Luther's thought of compulsory education led the development of primary education in German Protestant states from 16 to 18 century. It is in this reform that the earliest and truly modern primary education came into being.
