In 1573, Charles IX's fragile mental state and constitution deteriorated further, but the heir presumptive, his brother Henry, was elected king of Poland. Due to Henry's support of suppressing Protestant worship, moderate Catholic lords, called Malcontents, supported a plot to raise Charles' youngest brother, Francis of Alençon, to the throne of France instead. Alençon appeared willing to compromise in religious affairs, making him an appealing option to those tired of violence. Allied with the Protestants, the Malcontents executed several plots to seize power.
