When the news of the Chongzhen emperor's death reached Nanjing in May 1644, the fate of the heir apparent was still unknown. But court officials quickly agreed that an imperial figure was necessary to rally loyalist support. In early June, a caretaker government led by the Prince of Fu was created. By the time he arrived in the vicinity of Nanjing, the prince could already count on the support of both Ma Shiying and Shi Kefa. He entered the city on June 5 and accepted the title "protector of the state" the next day. Prodded by some court officials, the Prince of Fu immediately begin to consider ascending the throne. The prince had a problematic reputation in terms of Confucian morality, so some members of the Donglin faction suggested the Prince of Lu as an alternative. Other officials noted that the Prince of Fu, as next in line by blood, was clearly the safer choice. In any case, the so-called "righteousness" faction was not keen to risk a confrontation with Ma, who arrived in Nanjing with a large fleet on June 17. The Prince of Fu was crowned as the Hongguang emperor on June 19. It was decided that the next lunar year would be the first year of the Hongguang reign.
