Matilda returned to Normandy in 1125 and spent about a year at the royal court, where her father was still hoping that his second marriage would generate a son. If this failed to happen, Matilda was Henry's preferred choice, and he declared that she was to be his rightful successor if he should not have another legitimate son. The Anglo-Norman barons were gathered together at Westminster on Christmas 1126, where they swore in January to recognise Matilda and any future legitimate heir she might have.
