Largely forgotten now, the League of Evangelical Students was an early 20th Century forerunner to such contemporary evangelical student fellowships as InterVarsity, Campus Crusade for Christ and Reformed University Ministries. Its mission statement declared it to be "an inter-denominational and international student movement for the defense and propagation of the Gospel in the modern student-world."
Organized 1925, the League grew to have over 60 chapters across the campuses of America, with an affiliated chapter located in China. Its leadership came primarily from the conservative ranks of the northern Presbyterian Church (PCUSA) and it is notable that many of these same leaders were later to figure prominently in the formation of both Westminster Theological Seminary 1929 and the Orthodox Presbyterian Church 1936. The Evangelical Student magazine ran 1926-1939, with the first issue appearing April, 1926. In addition to the magazine, the League held annual conferences which were hosted by various chapters. Three articles appearing in the first issue give something of the background and purpose of the organization. The final issue of the magazine was January 1939 (Vol 14, no 1).
