And historical records for post-Roman and early medieval Britain are just very limited. Very few documents exist from this period, and those that do exist (like the Anglo-Saxon Chronicle: [1]) limit themselves to discussing events of great importance: the births, deaths, and major acts of royalty, battles won and lost, major weather events, and unusual celestial phenomena.
