Due to its strategic significance, Armenia was constantly fought over and passed back and forth between the dominion of Iran and the Ottomans. At the height of the Ottoman-Persian Wars, Yerevan changed hands fourteen times between 1513 and 1737. In 1604, Shah Abbas I pursued a scorched earth campaign against the Ottomans in the Ararat valley. The old Armenian town of Julfa in the province of Nakhichevan was taken early in the invasion. From there, Abbas' army fanned out across the Araratian plain. The Shah pursued a careful strategy, advancing and retreating as the occasion demanded, determined not to risk his enterprise in a direct confrontation with stronger enemy forces. While laying siege to Kars, he learned of the approach of a large Ottoman army, commanded by Djghazadé Sinan Pasha. The order to withdraw was given; but to deny the enemy the potential to resupply themselves from the land, he ordered the wholesale destruction of the Armenian towns and farms on the plain. As part of this, the whole population was ordered to accompany the Iranian army in its withdrawal. Some 300,000 people were duly herded to the banks of the Araxes River. Julfa was treated as a special case; he entrusted its evacuation to a renegade Georgian prince, Hanis Thahmaz-Ghuli Bek. He told Julfa's residents that they had three days to prepare for deportation to Iran; anyone still in town after those three days would be killed. Those who attempted to resist the mass deportation were killed outright. The Shah had previously ordered the destruction of the only bridge, and although Iranian soldiers helped the Julfaites to cross on horses and camels, the rest of the deportees had to cross on their own, so people were forced into the waters, where a great many drowned, carried away by the currents, before reaching the opposite bank. This was only the beginning of their ordeal. One eyewitness, Father de Guyan, describes the predicament of the refugees thus: Unable to maintain his army on the desolate plain, Sinan Pasha was forced to winter in Van. Armies sent in pursuit of the Shah in 1605 were defeated, and by 1606 Abbas had regained all of the territory lost to the Turks earlier in his reign. The scorched-earth tactic had worked, though at a terrible cost to the Armenian people. Of the 300,000 deported, it is estimated that under half survived the march to Isfahan. In the conquered territories, Abbas established the Erivan khanate, a Muslim principality under the dominion of the Safavid Empire. As a result of the continuous wars in the region and Shah Abbas I's deportation of much of the Armenian population from the Ararat valley and the surrounding region, in 1605 Armenians formed less than 20% of its population.
