King Diogo I skillfully replaced or outmaneuvered his entrenched competitors after he was crowned in 1545. He faced a major conspiracy led by Pedro I, who had taken refuge in a church, and whom Diogo in respect of the Church's rule of asylum allowed to remain in the church. However, Diogo did conduct an inquiry into the plot, the text of which was sent to Portugal in 1552 and gives us an excellent idea of the way in which plotters hoped to overthrow the king by enticing his supporters to abandon him.
