This article is about the particular significance of the century 1101–1200 to Wales and its people. Events 1102 Henry I of England has a series of charges drawn up against the rebel Robert of Bellême, Earl of Shrewsbury and, when Robert refuses to answer to them, has Robert's former vassal and ally Iorwerth ap Bleddyn, prince of Powys, persuaded to besiege and capture Robert's castles in Shropshire; Iorwerth also delivers his own brother Maredudd ap Bleddyn to the king. The king banishes Robert and his brothers from England and Wales; his brother Arnulf of Montgomery, lord of Pembroke, goes to serve his father-in-law, Muirchertach Ua Briain, High King of Ireland. Gerald de Windsor is appointed by Henry I of England as Constable of Pembroke Castle. 1103 Iorwerth ap Bleddyn, prince of Powys, having been insufficiently rewarded for his actions the previous year, again rebels against Henry I and is arraigned before a royal tribunal at Shrewsbury, convicted and imprisoned, leaving his brother Cadwgan ap Bleddyn as sole ruler of the parts of Powys not already in Norman hands. 1109 Nest ferch Rhys is abducted from Cilgerran Castle by Owain ap Cadwgan, son of Cadwgan ap Bleddyn. 1110 Cadwgan ap Bleddyn loses Ceredigion to the Norman Gilbert Fitz Richard. Iorwerth ap Bleddyn is released from prison. Philip de Braose, 2nd Lord of Bramber, rebels against King Henry I of England, and his estates are confiscated. 1111 Madog ap Rhiryd, an ally of Owain ap Cadwgan, kills Iorwerth ap Bleddyn (Owain's uncle) near Llanfair Caereinion, soon afterwards also killing Iorwerth's brother Cadwgan ap Bleddyn at Welshpool (Y Trallwng) so that Owain takes over their possessions in Powys. 1112 William de Braose regains possession of the estates lost two years earlier. 1113 Gruffydd ap Rhys of Deheubarth, heir of Rhys ap Tewdwr, returns from exile in Ireland. Maredudd ap Bleddyn captures Madog ap Rhiryd and sends him to Maredudd's nephew, Owain ap Cadwgan, Prince of Powys, who takes revenge for the killing of his father by having Madog's eyes gouged out. 1114 King Henry I of England invades Gwynedd, obliging Gruffudd ap Cynan to pay homage to him. 1115 Bernard replaces Wilfred as Bishop of St David's, as a result of Henry I's determination to take the diocese out of Welsh control.
