1847, originally a Christian theological position that God immediately created a soul for each person born; from creation + -ism. As a name for the religious reaction to Darwin, opposed to evolution, it is attested from 1880.
James Ussher (1581-1656), Archbishop of Armagh, Primate of All Ireland, and Vice-Chancellor of Trinity College in Dublin was highly regarded in his day as a churchman and as a scholar. Of his many works, his treatise on chronology has proved the most durable. Based on an intricate correlation of Middle Eastern and Mediterranean histories and Holy writ, it was incorporated into an authorized version of the Bible printed in 1701, and thus came to be regarded with almost as much unquestioning reverence as the Bible itself. Having established the first day of creation as Sunday 23 October 4004 B.C. ... Ussher calculated the dates of other biblical events, concluding, for example, that Adam and Eve were driven from Paradise on Monday 10 November 4004 BC, and that the ark touched down on Mt Ararat on 5 May 1491 BC "on a Wednesday".
