Walter de Lacy, Lord of Meath

Walter de Lacy ( 1172 – 1241) was lord of Meath in Ireland. He was also a substantial landowner in Weobley, Herefordshire, in Ludlow, Shropshire, in Ewyas Lacy in the Welsh Marches, and several lands in Normandy. He was the eldest son of Hugh de Lacy, a leading Cambro-Norman baron in the Norman invasion of Ireland, and Rohese of Monmouth.

Life With his father he built Trim Castle in Trim, County Meath.

During the revolt of Prince John "lackland", Lord of Ireland, against his brother, King Richard "the lionheart", in 1193–94, Walter de Lacy joined with John de Courcy to support Richard. De Lacy apprehended some knights loyal to John along with Peter Pipard, John's justiciar in Ireland.

De Lacy did homage to Richard for his lands in Ireland in 1194, receiving his lordship of Meath. After mounting the throne of England in 1199, Prince John wrote to his justiciar in Ireland to complain that de Courcy and de Lacy had destroyed his land of Ireland. Walter had made John his enemy. As de Braose was an absentee, de Lacy served as de Braose's deputy in Limerick. After de Lacy's brother Hugh de Lacy, 1st Earl of Ulster, had taken Fitzhenry prisoner, John in March 1208 acquiesced in giving Walter de Lacy a new charter for his lands in Meath. By this time, John had begun his infamous persecution of de Lacy's father-in-law, de Braose, who fled to Ireland. John attacked eastern Meath, and was joined by 400 of de Lacy's deserting followers.

In 1211 de Lacy erected the castle on Turbet Island in the abortive Anglo-Norman attempt to gain control of West Ulster.

Attempting to secure support in Ireland against the brewing revolt that would lead to Magna Carta, John began negotiations to restore de Lacy to his lands in Meath in the summer of 1215. 9= 10= 11= 12= William fitzBaderon 13= Hawise of Monmouth 14= Sir Gilbert Fitz Richard, Lord of Clare 15= Adeliza/Alice de Clermont 16= Walter de Lacy 17= Emma or Emmelina 18= 19= 20= 21= 22= 23= 24= Baderon 25= 26= 27= 28= Richard fitz Gilbert 29= Rohese Giffard 30= Hugh I, Count of Clermont-en-Beauvaisis 31= Margaret de Roucy
