Ludwigism was founded in Hesse in the 15th Century. Its ideology aligns to modern day Anglicanism. The head of the Ludwigist Church is the Hessian Monarch, and its capital is in Ludwigsburg, specifically Ludwig's Cathedral.
Currently Ludwigism is only found in the majority of two countries: Hamburg, and Hesse, along with their respective vassals. The surrounding area around them also consists of Ludwigists, specifically Thuringia and Westphalia, from when they were under Hessian rule. In the 16th Century, however, Thuringia began to revert back to Catholicism, and Westphalia to Dutch Reformed.
