Rudolf II summons the Diet of the Holy Roman Empire to raise money
for repairing forts on the frontier with the Ottoman Empire. Those
hostile to the Protestant Joachim Frederick of Brandenburg contest
his claim to the bishopric of Magdeburg, but are ultimately
quashed. Another polemical topic for discussion is the city of
Aachen, where Protestants have recently taken control of the city
government.
