Over the years, however, Prince Gong's relationship with Empress Dowager Cixi deteriorates as she becomes more power-hungry and he starts distancing himself from her. At the same time, the Empress Dowager's position in the imperial court gradually becomes more prominent, especially after the death of her son, the Tongzhi Emperor. The Tongzhi Emperor's cousin Zaitian, who succeeds him as the Guangxu Emperor, becomes a puppet ruler under Empress Dowager Cixi's control. Over time, Empress Dowager Cixi consolidates power in her hands and becomes the sole "de facto" ruler when her co-regent, Empress Dowager Ci'an, dies under mysterious circumstances. Prince Gong's standing in the imperial court declines as Empress Dowager Cixi increasingly distrusts him and gradually reduces his power by removing him from key appointments.
