Georgian monasteries were listed in Jerusalem. Saladin's biographer, Bahā' ad-Dīn ibn Šaddād, reports that after the Ayyubid conquest of Jerusalem in 1187, Tamar sent envoys to the sultan to request that the confiscated possessions of the Georgian monasteries in Jerusalem be returned. Saladin's response is not recorded, but the queen's efforts seem to have been successful: Jacques de Vitry, who attained to the bishopric of Acre shortly after Tamar's death, gives further evidence of the Georgians’ presence in Jerusalem. He writes that the Georgians were – in contrast to the other Christian pilgrims – allowed a free passage into the city, with their banners unfurled. Ibn Šaddād furthermore claims that Tamar outbid the Byzantine emperor in her efforts to obtain the relics of the True Cross, offering 200,000 gold pieces to Saladin who had taken the relics as booty at the Battle of Hattin – to no avail, however. Golden age Feudal monarchy Georgia's political and cultural exploits of Tamar's epoch were rooted in a long and complex past. Tamar owed her accomplishments most immediately to the reforms of her great-grandfather David IV (r. 1089–1125) and, more remotely, to the unifying efforts of David III and Bagrat III who became architects of a political unity of Georgian kingdoms and principalities in the opening decade of the 11th century. Tamar was able to build upon their successes. By the last years of Tamar's reign, the Georgian state had reached the zenith of its power and prestige in the Middle Ages. Tamar's realm stretched from the Greater Caucasus crest in the north to Erzurum in the south, and from the Zygii in the northwest to the vicinity of Ganja in the southeast, forming a pan-Caucasian empire, with the loyal Zachariad regime in northern and central Armenia, Shirvan as a vassal and Trebizond as an ally. A contemporary Georgian historian extols Tamar as the master of the lands "from the Sea of Pontus [i.e., the Black Sea] to the Sea of Gurgan [i.e., the Caspian Sea], from Speri to Derbend, and all the Hither and the Thither Caucasus up to Khazaria and Scythia." The royal title was correspondingly aggrandized. It now reflected not only Tamar's sway over the traditional subdivisions of the Georgian realm, but also included new components, emphasizing the Georgian crown's hegemony over the neighboring lands.
