Why did Charles I give up his role in administering Austria in November 1918?

In November 1918, Emperor Charles I relinquished his role in the administration of the state due to the collapse of the Habsburg monarchy and the widespread loss of faith in his rule among the population, including German Austrians.1

Following the disintegration of the empire and the rise of revolutionary agitation and republican sentiment, Charles acted on the advice of Heinrich Lammasch, a respected legal authority who had been tasked with supervising the orderly transfer of power. On November 11, 1918, Charles issued a proclamation stating that he relinquished all participation in the administration of the state and acknowledged "in advance the decision to be taken by German Austria".1

It is important to note that while Charles renounced his political authority, he did not formally abdicate his throne at that time. He was later deposed by the Austrian parliament in April 1919.2
