By the time of King Zhao's coronation, his father King Kang and grandfather King Cheng had conquered and colonized the Central Plains of China, forcing most of the northern and eastern tribal peoples into vassalage. Only the Dongyi of eastern Shandong continued their resistance, but they were no longer a threat to Zhou rule. As result, King Zhao inherited a prospering kingdom, and could afford to build a new ancestral temple for his father. This temple, known as “Kang gong”, was built in line with ritual reforms of the time and would grow into “one of the two central temples of dynastic worship”, the other being the much older “jinggong” temple.
