LLYWELYN ap SEISYLL (bu f. 1023), brenin Deheubarth a Gwynedd | Y Bywgraffiadur Cymreig

LLYWELYN ap SEISYLL (bu f. 1023), brenin Deheubarth a Gwynedd

Enw: Llywelyn Ap Seisyll
Dyddiad marw: 1023
Priod: Angharad wraig Cynfyn ap Gwerstan
Plentyn:
Rhiant: Prawst ferch Elisedd
Rhyw: Gwryw
Galwedigaeth: brenin Deheubarth a Gwynedd
Maes gweithgaredd: Milwrol; Gwleidyddiaeth a Mudiadau Gwleidyddol; Teuluoedd Brenhinol a Bonheddig
Awdur: Thomas Jones Pierce

Ni wyddys ddim am ei dad, eithr yn ôl rhai achau diweddar yr oedd ei fam, Prawst, yn ferch Elisedd, mab iau i Anarawd ap Rhodri Fawr. Gan i Lywelyn briodi Angharad, merch Maredudd ab Owain ap Hywel Dda, yr oedd ganddo hawl, o bell, i olyniaeth yn Neheubarth a Gwynedd, hawl y gellid, yn amgylchiadau'r cyfnod, ei gwneuthur yn sylwedd gan arweinydd nerthol ac uchelgeisiol. Un felly'n union oedd Llywelyn; a chan iddo orchfygu, yn 1018, y gwr a gipiasai'r deyrnas, sef Aeddan ap Blegywryd, a hefyd orchfygu Rhain, ymhonnwr o Iwerddon, yn 1022, daeth yn bennaeth yn y De. Estynnodd ei reolaeth hefyd am rai blynyddoedd dros ran fawr o Gymru — cyfnod cofiadwy yn hanes Cymru a barnu oddi wrth y cronicl. Prif hawl Llywelyn ap Seisyll i enwogrwydd, fodd bynnag, ydyw'r ffaith mai ef oedd tad Gruffydd ap Llywelyn; gwnaethpwyd ei yrfa nodedig ef yn bosibl gan esiampl ei dad — yr oedd ei hawl ef i awdurdod yn seiliedig i raddau helaeth ar y cyfnod byr o benarglwyddiaeth ‘de facto’ Llywelyn.
