Tyrone

Tyrone was a Gaelic kingdom of Ulster ruled from Dungannon by the O'Neills. In 1337 Aodh Reamhar led the dynasty after the collapse of the Norman earldom of Ulster opened the east to its expansion.

Conn Bacagh O'Neill became Earl of Tyrone in 1542. Hugh O'Neill's Nine Years' War ended in surrender in 1603; his flight with other Ulster earls in 1607 was followed by forfeiture of the title and the Plantation of Ulster.
