Abraham Kuyper (1837–1920), a self-styled “Christian Democrat” who dominated two generations of Dutch political history, has received passing mention rather than scholarly examination outside the Netherlands. Ernst Troeltsch, speaking of Kuyper's theological work, called him a key figure in the development of modern Calvinistic thought. And Michael Fogarty mentions Kuyper's influence in building “one of the most successful, and in many ways the most instructive political, economic and social movements to be found anywhere in the Christian world.” But, apart from such brief notes, there is little. We propose in this article to sketch Kuyper's career and summarize the ideas with which he attacked Liberalism.
