What happened 1097 AD

Westminster Hall, the oldest existing part of the Palace of Westminster, was erected in 1097 by King William II ('William Rufus'), at which point it was the largest hall in Europe.

Alexios I Komnenos persuaded many of the princes to pledge allegiance to him. He also convinced them their first objective should be Nicaea. Buoyed by their success at Civetot, the over-confident Seljuks left the city unprotected, thus enabling its capture after the siege of Nicaea in May–June 1097.

The first experience of Turkish tactics occurred when a force led by Bohemond and Robert was ambushed at the Battle of Dorylaeum in July 1097. The Normans resisted for hours before the arrival of the main army caused a Turkish withdrawal.

The Crusader army marched to the former Byzantine city of Antioch that had been in Muslim control since 1084. The Crusaders began the siege of Antioch in October 1097 tell Antioch was captured.
