The Georgian Church (founded in the early part of the fourth century) was an offshoot from the Greek Church, with which she has always remained in communion, although from the middle of the sixth century the Patriarch or Katholikos of the Georgian Church declared himself independent. Torn asunder by internal discords and exposed to the successive attacks of Greeks, Persians, Arabs, Turks and Mongols, the history of this heroic warrior people is one of almost uninterrupted warfare against foreign foes and of fiercely contested feuds between native chiefs: the reigns of one or two powerful monarchs who secured for their subjects brief intervals of peace, serving only to bring out in more striking contrast the normally unsettled state of the country. The fierce independent spirit of the Georgians that could not brook a foreign rule has often exasperated well-nigh to madness the fury of their Muhammadan neighbours, when they failed to impose upon them either their civil authority or their religion. It is this circumstance—that a change of faith implied loss of political independence—which explains in a great measure the fact that the Georgian Church inscribes the names of so many martyrs in her calendar, while the annals of the Greek Church during the same period have no such honoured roll to show. It was not until after Georgia had been overrun by the devastating armies of the Mongols, leaving ruined churches and monasteries and pyramids of human heads to mark the progress of their destroying hosts, and consequently the spiritual wants of the people had remained long unprovided for, owing to the decline in the numbers and learning of the clergy—that Christianity began to lose ground. [249] Even among those who still remained Christian, some added to the sufferings of the clergy by plundering the property of the Church and appropriating to their own use the revenues of churches and monasteries, and thus hastened the decay of the Christian faith.
