竇武
In 168, Emperor Huan died without a son. Empress Dou became empress dowager and regent. She and her father examined the potential successors within the imperial Liu clan, and they settled on the 12-year-old Liu Hong (劉宏), the Marquess of Jieduting, and he ascended the throne as Emperor Ling. Empress Dou continued to serve as regent. She trusted Chen and her father Dou Wu, and gave them great power.
