The first cathedral was built on the present site in 700 when Bishop Hædde built a new church to house the bones of St Chad, which had become the centre of a sacred shrine to many pilgrims when he died in 672. The burial in the cathedral of the kings of Mercia, Wulfhere in 674 and Ceolred in 716, further increased the city's prestige.[12] In 786 King Offa made the city an archbishopric with authority over all the bishops from the Humber to the River Thames; his appointee was Archbishop Hygeberht. After King Offa's death in 796, Lichfield's power waned; in 803 the primacy was restored to Canterbury by Pope Leo III after only 16 years.
