 Stephen took steps to solidify his new regime but faced threats both from neighbouring powers and from opponents within his kingdom.In 1139, Matilda crossed to England to take the kingdom by force, supported by her half-brother Robert of Gloucester and her uncle King David I of Scotland, while Geoffrey focused on conquering Normandy.Matilda's forces captured Stephen at the Battle of Lincoln in 1141, but the Empress' attempt to be crowned at Westminster collapsed in the face of bitter opposition from the London crowds.
