While we’re at the topic of religion and politics: I noted that the British press over the last six months has reported rumours about Tony Blair converting to the Roman Catholic church. The link between religion and politics is indeed interesting in the case of Blair who – perhaps with the exception of a couple of Norwegian prime ministers – must be the most openly religious government leader in North-Western Europe in later years.
Anyway, let me just point out that Denmark has in fact had a Catholic prime minister as Ludvig Holstein-Ledreborg who converted to Catholicism a young man, served as prime minister from August to October 1909. Holstein-Ledreborg was a merited leader of the Liberals who had resigned from politics in 1890 but was brought back as an emergency solution during a political crisis.
If we enlist the services of the Department of Contra-factual Political Science and History, it is not unlikely that Denmark could have had a Jewish prime minister (or to be more correct: A prime minister with a Jewish background) during the First World War as King Christian X found it much easier to get along with Edward Brandes than with Social Liberal prime minister C. Th. Zahle. (Why “Jewish background”? Because Brandes was an outspoken atheist).
Finally, Denmark has had a theologian serving as prime minister in recent times: Poul Hartling even worked as a vicar for a period before entering politics and becoming leader of the Liberal Party (1965-1977), foreign minister (1968-1971) and prime minister (December 1973-January 1975). If I’m not completely mistaken, Svend Auken, leader of the Social Democrats from 1987 to 1992 and Environment Minister 1993-2001, has also made some appearances as a layman preacher.
