Step-by-step explanation:
The Anglo-Saxons practiced a pagan religion when they invaded Britannia. They believed in a pantheon of gods and goddesses, with the most important deity being Woden, the god of war and wisdom. They also believed in supernatural beings such as elves and dragons. The conversion to Christianity began in the late 6th and early 7th centuries, with the influence of missionaries from the Roman Catholic Church, and by the 8th century, most Anglo-Saxons had adopted Christianity.
