Led by Timur, the Timurids ultimately conquered the Christian monarchy and made it a tributary state that kept its independence and religion.

Bagrat's son and successor, George VII, put up a stiff resistance and had to spend much of his reign (1395–1405) fighting the Timurid invasions.

By the time George VII was forced to accept Timur's terms of peace and agree to pay tribute, he was a master of little more than "gutted towns, ravaged countryside and a shattered monarchy".

[2] Timur's first appearance in the Caucasus was a response to Khan Tokhtamysh's marauding inroad into Northern Iran through the Caucasian lands in 1385.

Timur responded by launching a full-scale invasion of the small frontier countries, which lay between the western border of his emerging empire and Tokhtamysh's khanate.

[3][1] The death of thousands of soldiers in battle with Georgian troops led to the start of Timur’s new invasion of Georgia in the spring of 1387.

Timur's goal seems to have been to capture the Darial Pass in order to ultimately prevent the withdrawal of Georgian allied North Caucasian raiders and a possible Tokhtamysh invasion.

His army encamped on the banks of the Mtkvari, near Mahmud Abad, and began preparations for a great campaign against Tokhtamish.

A Georgian general Khimisha delayed the Timurids by tactical evasion, and those who were forewarned escaped to the caves and forests.

[7] After the war, of those who survived the fighting and reprisals, many thousands died of hunger and disease, and 60,000 survivors were enslaved and carried away by Timur's troops.

Timur made peace with George VII on condition that the King of Georgia supplied him troops during his campaign against Ottoman Empire and granted the Muslims special privileges.

[1] Once the Ottomans were defeated, Timur, back in Erzurum in 1402, decided to punish the king of Georgia for not having come to present his congratulations on his victory.

Having captured the fortress in August 1403, Timur sent his army to plunder and clear the frontier regions of Georgia and set out in pursuit of the retreating king George VII as far as Abkhazia.

[1] Timur then finally left the Caucasus and headed for Central Asia, where he died on February 19, 1405, while preparing for a massive invasion of China.
