Germany maintains a distinctive church-state arrangement inherited from the Weimar Constitution of 1919 and preserved in the 1949 Basic Law, under which registered members of recognized religious bodies, chiefly the Catholic and Protestant churches, pay a mandatory church tax collected by the state alongside income tax and transferred to the churches, a system that has driven a sustained wave of formal church exits since exiting membership is the only way to stop paying it, with hundreds of thousands of Germans doing so annually in recent years. This funding model has helped both major churches remain wealthy and institutionally significant, running major hospital, welfare and school networks, even as active religious practice and belief decline.
Germany's reckoning with the Holocaust has shaped its approach to religious minorities and hate speech considerably, including strict laws against Holocaust denial and incitement, alongside constitutionally protected religious freedom, though debate over Muslim integration, headscarf bans for public sector employees in some states, and, since 2015, the arrival of large numbers of Syrian and other Muslim refugees have remained politically contentious, feeding the rise of parties critical of both immigration and Islam's growing public visibility.
