Enlightenment against religion
Just before the Enlightenment religion was the dominant political pressure across Europe. The Catholic Chapel wielded tremendous spiritual authority throughout the Dark Ages, as evidenced through the effective investiture debate from the eleventh century despite the Renaissance, monarchs ongoing to make use of religion to legitimize their authority. However, the Enlightenment, sometimes known as age Reason, challenged the supremacy of faith within the political and social existence of Europe.
The Catholic Chapel
Throughout the first Dark Ages, the Catholic Chapel, located in Rome, developed its spiritual and political energy. In 496 Clovis, king from the Hot dogs, transformed into Catholicism and used the religion to unify his people. In 754 Pepin rapid contributed the land that grew to become the Papal States towards the papacy following the pope formally legitimized him as king. The truth that religion am frequently accustomed to legitimize a ruler shows its energy throughout this time around.
The Investiture Debate
The Catholic Chapel cemented its energy within the eleventh century using the investiture debate. Before the eleventh century, chapel authorities were hired not through the pope but by nobleman who required bribes, an exercise referred to as simony. Pope Gregory VII banned simony in 1075, so when Holy Roman Emperor Henry IV ongoing the practice, Gregory excommunicated him and declared his rule illegitimate, and by doing this started a rebellion against him by German princes. With no pope's spiritual authority, Henry's energy was considered meaningless.
Even if your Dark Ages had ended using the Renaissance, religion still held tremendous energy within the political realm of Europe. Many monarchs required more absolute control of their subjects and used religion to warrant their elevated authority, proclaiming that as nobleman they'd a divine to rule absolutely. The favourite such king was Louis XIV of France, who ruled France being an absolute monarch for 72 years.
