The spectacle of two rival Popes, each claiming to be the rightful successor of St. Peter and the sole infallible head of the Church, very naturally led men to question the claims and infallibility of both. It gave the reverence which the world had so generally held for the Roman See a rude shock, and one from which it never recovered.

THE CHURCH COUNCILS OF PISA AND CONSTANCE.—Finally, in 1409, a general council of the Church assembled at Pisa, for the purpose of composing the shameful quarrel. This council deposed both Popes, and elected Alexander V. as the supreme head of the Church. But matters instead of being mended hereby were only made worse; for neither of the deposed pontiffs would lay down his authority in obedience to the demands of the council, and consequently there were now three Popes instead of two.

In 1414 another council was called, at Constance, for the settlement of the growing dispute. Two of the claimants were deposed, and one resigned. A new Pope was then elected,—Pope Martin V. In his person the Catholic world was again united under a single spiritual head. The schism was outwardly healed, but the wound had been too deep not to leave permanent marks upon the Church.

THE REVOLT OF THE TEMPORAL PRINCES.—Taking advantage of the declining authority of the Papal See, the temporal rulers in France, Germany, and England successively revolted, and freed themselves from the authority of the Papacy as touching political or governmental affairs. But it must be borne in mind that the princes or governments that at this time repudiated the temporal authority of the Papal See, did not think of challenging the claims of the Popes to recognition as the supreme head of the Church, and the rightful arbiters in all spiritual matters. At the very time that they were striving to emancipate themselves from papal control in temporal matters, they were lending the Church all their strength to punish heresy and schism. Thus the Albigenses [Footnote: See p. 493.] in Southern France, the Lollards [Footnote: See p. 491.] in England, and the Hussites [Footnote: See p. 506.] in Bohemia, were extirpated or punished by the civil authorities, acting either in accordance with the then universal idea of how heresy should be dealt with, or in obedience to the commands of the Roman See.

CHAPTER XLIV.

CONQUESTS OF THE TURANIAN TRIBES.

THE HUNS AND THE HUNGARIANS.—The Huns, of whom we have already told, were the first Turanians that during historic times pushed their way in among the peoples of Europe (see p. 345).

The next Turanian invaders of Europe that we need here notice were the Magyars, or Hungarians, another branch of the Hunnic race, who in the ninth century of our era succeeded in thrusting themselves far into the continent, and establishing there the important Kingdom of Hungary. These people, in marked contrast to almost every other tribe of Turanian origin, adopted the manners, customs, and religion of the peoples about them— became, in a word, thoroughly Europeanized, and for a long time were the main defence of Christian Europe against the Turkish tribes of the same race that followed closely in their footsteps.

THE SELJUKIAN TURKS.—The Seljukian Turks, so called from the name of one of their chiefs, are the next Tartar people that thrust themselves prominently upon our notice. It was the capture of the holy places in Palestine by this intolerant race, and their threatening advance towards the Bosporus, that alarmed the Christian nations of Europe, and led to the First Crusade.

The blows dealt the empire of the Seljuks by the crusaders, and disputes respecting the succession, caused the once formidable sovereignty to crumble to pieces, only, however, to be replaced by others of equally rapid growth, destined to as quick a decay.
