Extremely excited to receive this awesome cover from fellow ICCC member, Dashdondov J! Thank you very much! It is my second Mongolian cover!
The portrait stamp franked on the front of cover was issued in 2007 to commemorate the 780th Death Anniversary of Genghis Khan.
He came to power by uniting many of the nomadic tribes of northeast Asia. After founding the Mongol Empire and being proclaimed "Genghis Khan", he started the Mongol invasions that would ultimately result in the conquest of most of Eurasia. These included raids or invasions of the Kara-Khitan Khanate, Caucasus, Khwarezmid Empire, Western Xia and Jin dynasties. These campaigns were often accompanied by wholesale massacres of the civilian populations - especially in Khwarezmia. By the end of his life, the Mongol Empire occupied a substantial portion of Central Asia and China.
Back of the cover shows stamps from the "Swans" series. They were issued in 1987.
This cover was posted from Ulan Bator or Ulaanbaatar, the capital and largest city of Mongolia on 10th Sept 2010 and took 11 days to reach me!
