Conqueror - someone who is victorious by force of arms. A combatant who is able to defeat rivals. A subjugator. Triumphant. These are definitions with the same message - a Winner.
As what was mentioned from this announcement, the Conqueror Achievement Medal has now been created for those who have officially reached the Conqueror rank status ever since it was implemented in May 2007.
Now, this will be a rare medal as there are very few people who have been Conquerors and this is an achievement that not everyone can easily accomplish.
I have researched the forum for information of who has been Conqueror. Special thanks to Blitzaholic's thread, and anyone else who contributed in making a record of those who have been on top throughout the years (thank you also for excluding anyone who may have cheated his way to become Conqueror).
From this post, we can see that it was Gibbom who got to be the first Conqueror way back in May 2007. Anyone who has reached Conqueror rank starting from him will get this special medal to signify their achievement as it is not easy to be on the top spot among all current players who are as competitive as one can be.
Congratulations Conquerors!!!
