To make calvinist in character or principles; to convert to Calvinism or to influence someone toward Calvinist beliefs.
From Calvin (the reformer) plus the suffix -ize (to make, cause to become, or convert to). This verb was particularly used during the Reformation when religious movements were actively converting populations.
During the Protestant Reformation, different regions attempted to 'calvinize' their populations with varying degrees of success—Scotland became heavily calvinized, while Southern Europe remained largely Catholic, creating the religious divisions that still partly define European culture today.
