Already in 1844, Ludwig was confronted with the Beer riots in Bavaria. During the revolutions of 1848 the king faced increasing protests and demonstrations by the students and the middle classes. The King had ordered to close the university in February and on 4 March a large crowd assaulted the Armory to storm the Munich Residenz. Ludwig's brother Prince Karl managed to appease the protesters, but now the royal family and the Cabinet turned against Ludwig. He had to sign the so-called "March Proclamation" with substantial concessions. On 16 March 1848 it was followed by renewed unrest because Lola Montez had returned to Munich after a short exile. Ludwig had to let her be searched by the police on 17 March, which was the worst humiliation for him. Not willing to rule as a constitutional monarch, Ludwig abdicated on 20 March 1848 in favour of his eldest son, Maximilian.
