The Khwarezm-Shâh Empire
Category: Islamic Civilizations
Author: IhsanThe Founding
The origins of the Imperial Khwarezmshah family goes back to Anushtegin, who was a Turkish-origined palace officer in the Seljuk court. Anushtegin's son Qudbaddin Mohammed was appointed as the governor of the Khwarzem province by the Seljuk Sultan Berqyaruq in the year 1098. During his governorship, he assured his family's place in the region and after his death in 1128, his son Atsiz was appointed as the new governor by the Seljuk Sultan Sanjar.
Atsiz was a ruthless ruler; he laid heavy taxes on the people and began capturing strategic positions of the region. Sanjar organized three campaigns on Atsiz, and even tough Atsiz's forces were defeated, Sanjar let him to govern the region, because a new danger was coming from the Steppes: the Kara-Khitai. After Sanjar's army was crushed by these nomadic people at the Battle of Qatwan in 1141, Atsiz declared his independece but he submitted the Seljuk protectorate after Sanjar escaped from the rebel Oghuz. After Atsiz died in 1156, he was succeded by his son Il-Arslan.
Rise to Power
After Sanjar's death in 1157, Il-Arslan proclaimed his independence, defeated the Kara-Khitai and the Qarakhanids and captured important Transoxian towns like Bukhara and Samarkand. He died in 1172 and his son Alaeddin Takish became the new Khwarezm Shah.
Alaeddin Takish was a brilliant ruler and a good general. He defeated the Kara-Khitai and brought the Kipchaks under Khwarezmshah rule. He invaded Khorasan in 1183 and destroyed the Iraqi Seljuks in 1194. He spent his last years in fighting with the Assassins and captured the fort of Arslan-Gusha, one of their most important strongholds. He died in 1200 and his son Alaeddin Mohammed sat on the Khwarzemshah throne.
The early years of Alaeddin Mohammed's reign were spent for the struggle against the other Khwarezmshah princes. In 1214, he destroyed the Kara-Khitai Empire and the Gurid Sultanate of India. He also expanded the borders of the empire up to the Persian Gulf. Another campaign he was planning was the Invasion of China; altough China was already invaded by the Mongols
Collapse of the Empire
Now, there was a new power rising in the East: the Mongols commanded by Genghis Khan. In order to learn more about the power of the Mongols, Alaeddin Mohammed sent an envoy to Karakurum, the Mongol capital, and signed a treaty with him. After this, Genghis Khan sent a caravan to Otrar, but the Mongol merchants were massacred by Inaljik, the governor of that town, who also humiliated the Mongol emissaries. As a result, Genghis Khan invaded Transoxiana with his army. Even tough the Mongol army was outnumbered, Alaeddin Mohammed divided his army into small garrisons, a mistake which allowed Genghis Khan to capture important cities like Bukhara, Samarkand, Jend, Khokand and Urgench easily. Alaeddin Mohammed fled to a small Caspian island and died there in 1220.
Jalal-Al-Din Khwarezmshah became the new shah but his forces were defeated at the Battle of River Indus. He fled to Azerbaijan, attacked Rum Seljuk towns in Eastern Anatolia and captured Ahlat, an important Seljuk town. He was defeated by the Rum Seljuk Sultan Alaeddin Qaykubad I at the Battle of Yassi Chemen in 1230, and he was murdered in 1231. With his death, the Khwarzemshah Empire came to an end.
