Annexation to England

The resistance of the Irish aroused King Henry to decisive action. He had already shown himself uneasy about the influence Strongbow was obtaining over the Norman forces in Ireland, and apparently was impressed with the idea that Strongbow had the ambition to set himself up as a rival to the King himself. Henry summoned Strongbow back to England in order to obtain from him a clear explanation of his purposes. Strongbow was too busily engaged in war at the time to obey even the royal command, but when he found an opportunity, after an important success, he returned to England and came to a thorough understanding with his Sovereign. The result was that Henry called together a great Norman army, led it himself into Ireland, crushed all resistance offered to his conquering progress, accomplished his Norman invasion, and made Ireland a part of his dominions.
