By the deposition of Malachy II., and the transfer of supreme power to the long-excluded line of Heber, Brian completed the revolution which Time had wrought in the ancient Celtic constitution. He threw open the sovereignty to every great family as a prize to be won by policy or force, and no longer an inheritance to be determined by usage and law. The consequences were what might have been expected. After his death the O'Conors of the west competed with both O'Neills and O'Briens for supremacy, and a chronic civil war prepared the path for Strongbow and the Normans. The term "Kings with Opposition" is applied to nearly all who reigned between Brian's time and Roderick O'Conor's, meaning, thereby, kings who were unable to secure general obedience to their administration of affairs. During the remainder of his life, Brian wielded with accustomed vigour the supreme power. The Hy-Nials were, of course, his chief difficulty. In the year 1002, we find him at Ballysadare, in Sligo, challenging their obedience; in 1004, we find him at Armagh "offering twenty ounces of gold on Patrick's altar," staying a week there and receiving hostages; in 1005, he marched through Connaught, crossed the river Erne at Ballyshannon, proceeded through Tyrconnell and Tyrowen, crossed the Bann into Antrim, and returned through Down and Dundalk, "about Lammas," to Tara. In this and the two succeeding years, by taking similar "circuits," he subdued Ulster, without any pitched battle, and caused his authority to be feared and obeyed nearly as much at the Giant's Causeway as at the bridge of Athlone. In his own house of Kinkora, Brian entertained at Christmas 3,000 guests, including the Danish Lords of Dublin and Man, the fugitive Earl of Kent, the young King of Scots, certain Welsh Princes, and those of Munster, Ulster, Leinster and Connaught, beside his hostages. At the same time Malachy, with the shadow, of independence, kept his unfrequented court in West-Meath, amusing himself with wine and chess and the taming of unmanageable horses, in which last pursuit, after his abdication, we hear of his breaking a limb. To support the hospitalities of Kinkora, the tributes of every province were rendered in kind at his gate, on the first day of November. Connaught sent 800 cows and 800 hogs; Ulster alone 500 cows, and as many hogs, and "sixty loads of iron;" Leinster 300 bullocks, 300 hogs, and 300 loads of iron; Ossory, Desmond, and the smaller territories, in proportion; the Danes of Dublin 150 pipes of wine, and the Danes of Limerick 365 of red wine. The Dalcassians, his own people, were exempt from all tribute and taxation—while the rest of Ireland was thus catering for Kinkora.
