An Lushan
An Lushan had enjoyed many successes early on in his rebellion. His army numbered more than 160,000, and was growing rapidly. In the fall of 755, An Lushan won a major victory at Luoyang, the eastern capital of the Tang Dynasty. With civilians losing faith in the Tang Dynasty, and more people and generals joining An Lushan's newly proclaimed Great Yan Dynasty every day, it seemed that the Tang Dynasty was near its end. An Lushan set his eyes on Chang'an, the capital of Tang.
