The Japanese imperial court system allowed the Emperors to appoint key government officials, who held significant power and influence. The Fujiwara family strategically married their daughters into the imperial family, allowing them to gain favor and secure important positions within the government. Over time, the Fujiwara family held monopolistic control over the government, manipulating the appointments of officials to consolidate their power. This eventually led to the rise of the Fujiwara family as the de facto rulers of Japan, overshadowing the authority of the Emperor.
