When Otto the Great died, the smooth succession to the imperial throne of Otto II had long been guaranteed. Otto II had been king of Germany for twelve years and Emperor for five at the time of Otto the Great's death. Unlike his father, Otto II did not have any brothers to contest his claims to the throne. On May 8, the nobles of the Empire assembled before Otto II and, according to the Saxon Chronicler Widukind of Corvey, "elected" Otto II as his father's successor. One of Otto II's first acts was to confirm the rights and possessions of the Archbishop of Magdeburg. Although Otto II had succeeded peacefully to the throne, internal divisions of power still remained unaddressed. During his first seven years as Emperor, he was constantly occupied with maintaining Imperial power against internal rivals and external enemies.
