The conflict partly a religious one.

At first the struggle between English and Irish was purely a matter of race, but the religious element was soon introduced. Protestantism made no head in the country, and in 1579 a Papal Legate, Nicholas Sanders, came over to organize the tribes to unite in defence of the old religion. No man could ever persuade Irish parties to join for long, and Sanders's mission was in that respect a failure. But for the future the war was embittered by religious as well as racial hatred. In 1580 the Pope sent over a body of Italian and Spanish mercenaries to aid the rebels; but this force was blockaded by Lord Grey in its camp at Smerwick, a harbour in Kerry, and every man was put to the sword. At a later date Philip of Spain sent similar and equally ineffective help.

Desmond's Rebellion.

The two chief struggles of the Irish against the establishment of the English rule were that of the tribes of Munster in 1578-83, and that of the tribes of Ulster in 1595-1601. The former was led by Garrett Fitzgerald, Earl of Desmond, the greatest lord of the South, the descendant of one of those Anglo-Norman families which had become more Irish than the Irish themselves. In his desperate struggle with Lord-Deputy Grey and the English colonists in Munster, he saw all the land from Galway to Waterford harried into a wilderness, and was killed at last as a fugitive in the hills.

Tyrone's Rebellion.—Expedition of Essex.

The Ulster rebellion of Hugh O'Neil, Earl of Tyrone, the head of the greatest of the native Irish septs, was far more formidable than that of the Fitzgeralds. The English could for a long time do nothing against him. In 1598 he defeated an army of 5000 men on the Blackwater and slew its leader, Sir Henry Bagenal, and most of his followers. Tyrone sent for aid to Spain, and so moved Queen Elizabeth's fears that she despatched against him the largest English force that ever went over-sea in her reign. An army of 20,000 men was placed under Robert Devereux, the young Earl of Essex, whom the queen loved most of all men in her later years, and sent over to Dublin. Essex, though he had won much credit for courage in Holland, and at the capture of Cadiz, was not a great general. He pacified Central and Southern Ireland, but did not succeed in crushing Tyrone. It would seem that he was disgusted at the cruelty and treachery of his predecessors in the government of Ireland, and wished to admit the rebels to submission on easy terms. At any rate, he made a truce with Tyrone in 1600, promising that the queen should grant him toleration in matters of religion, and leave him his earldom. Essex returned to England to get these terms ratified, but was received very coldly by his mistress and her council, who had sent him to Ireland to suppress, not to condone, the rebellion. His treaty was not confirmed, and the war with Tyrone went on. The earl got 7000 men from Spain, and ravaged all Central Ireland, till he was defeated by Lord Montjoy in an attempt to raise the siege of Kinsale (1601). In the next year he made complete submission to the queen, and was pardoned and given back most of his Ulster lands. But the eight years of war had made Northern Ireland a desert, and the power of the O'Neils was almost broken.

Intrigues and execution of Essex.

Meanwhile the short stay of Essex in Ireland had led to a strange tragedy in London. The young earl had been so much favoured by the queen in earlier years, that he could not brook the rebuke that fell upon him for his dealings with Tyrone. Presuming on the almost doting fondness which his sovereign had shown for him, the headstrong young man plunged into seditious courses. He swore that his enemies in the council had calumniated him to the queen, and that he would be revenged on them and drive them out of office. With this object he gathered many of the Puritan party about him—for he was a strong Protestant—and resolved to overturn the ministry by force. He caught the Lord Chancellor, and locked him up, and then sallied out armed into the streets of London with a band of his friends, calling on the people to rise and deliver the queen from false councillors. But he had counted too much on his popularity; no one joined him, and he was apprehended and put in prison.

Elizabeth was much enraged with her former favourite, and allowed his enemies to persuade her into permitting him to be tried and executed for treason. When he was dead she bitterly regretted him (February, 1601).
