Madog inherited the kingship of Powys upon the death of his father in
1132. In 1156, impressed by his power, and feeling that he needed his
assistance in repelling the territorial ambitions of OWAIN AP GRUFFUDD
(RIN 2586) of Gwynedd, Madog yielded to the authority of King HENRY II
of England (RIN 761). In 1157 he assisted HENRY in his campaign against
OWAIN.
When Madog died in 1160 there was a struggle for succession. In 1149
Madog had allowed his nephews, Owain and Meurig, to rule Cyfieliog as an
appendage to the kingdom according to the custom of those times - never
intending that the area should be separated from the kingdom of Powys.
When Madog's son, Gruffudd, succeeded his father, Owain was able to
keep Cyfieliog and some adjacent areas for himself, leaving only
northern Powys for Gruffudd. This split the kingdom into two resulting
in Powys' loss of generally equal status with the kingdoms of Gwynedd
and Deheubarth.
Our line of descent flows through Madog's daughter, MARARED, who
married IOWERETH of Gwynedd and became the mother of LLYWELYN THE
GREAT.
