, returns to Hungary (from the
Illuminated Chronicle). Accompanied back to Hungary by German troops, Solomon entered
Székesfehérvár without resistance. He was ceremoniously "crowned king with the consent and acclamation of all Hungary" in September 1063, according to the
Illuminated Chronicle. The same source adds that the German monarch "seated" Solomon "upon his father's throne", against their boats. The Hungarians took Belgrade after
a siege of three months. However, the Byzantine commander, Niketas, surrendered the fortress to Duke Géza instead of the king; he knew that Solomon "was a hard man and that in all things he listened to the vile counsels of
Count Vid, who was detestable in the eyes both of God and men", according to the
Illuminated Chronicle. Division of the war-booty caused a new conflict between Solomon and his cousin, because the king granted only a quarter of the booty to the duke, who claimed its third part. Thereafter the duke negotiated with the
Byzantine Emperor's envoys and set all the Byzantine captives free without the king's consent. The conflict was further sharpened by Count Vid; the
Illuminated Chronicle narrates how the count incited the young monarch against his cousins by saying that as "two sharp swords cannot be kept in the same
scabbard", so the king and the duke "cannot reign together in the same kingdom". The Byzantines reoccupied Belgrade in the next year. Solomon decided to invade the Byzantine Empire and ordered his cousins to accompany him. Only Géza joined the king; his brother, Ladislaus, remained with half of their troops in the
Nyírség. Solomon and Géza marched along the valley of the river
Great Morava as far as
Niš. Here the locals made them "rich gifts of gold and silver and precious cloaks" and Solomon seized the arm of Saint
Procopius of Scythopolis. He donated the
relic to the
Orthodox monastery of
Syrmium (present-day Sremska Mitrovica, Serbia). After their return from the campaign, both Solomon and Géza began to make preparations for their inevitable conflict and were seeking assistance from abroad. They concluded a truce, which was to last "from the feast of
St Martin until the feast of
St George", from 11 November 1073 until 24 April 1074. However, Solomon chose to attack his cousin as soon as the German troops sent by his brother-in-law arrived in Hungary. The royal army crossed the river Tisza
and routed the troops of Géza, who had been abandoned by many of his nobles before the battle, at Kemej on 26 February 1074. A strong army soon arrived in Hungary, headed by Géza's brother-in-law, Duke
Otto I of Olomouc. In the decisive battle, which was
fought at Mogyoród on 14 March 1074, Solomon was defeated and forced to flee from the battlefield. ==Abdication==
