Penda was king of Mercia and one of the most powerful rulers in seventh-century Britain. He allied with Cadwallon of Gwynedd to defeat Edwin of Northumbria and later killed Oswald at Maserfield.
Although remembered as a pagan opponent of Christian kings, he permitted Christian preaching among people under his authority. He was defeated and killed by Oswiu at the Battle of the Winwaed in 655. His long success makes him essential to any account of how Mercia emerged as a major power.
Nicola Griffith’s Menewood places Penda of Mercia among the rulers whose campaigns shatter Edwin of Northumbria’s supremacy and force Hild and her household to survive a rapidly changing political map. M J Porter’s Warrior King makes Penda the dominant Mercian ruler at the height of his power, feared and courted across the competing kingdoms of Britain. Matthew Harffy’s Warrior of Woden and Killer of Kings bring him into Beobrand’s world as the pagan king whose wars repeatedly threaten Northumbrian allies and rulers. Fortress of Fury carries that conflict towards the later campaigns in which Penda’s long military ascendancy finally collides with Oswiu’s Northumbria.
