Diadem Trade League
This loosely-knit trading conglomerate incorporates worlds in the Diadem Subsector, and is named for an extensive Jump-1 trade route called the "Diadem" (because of its circular route). Trade has flourished via this Jump-1 route since its establishment in 1054.
The worlds of the Diadem Main are independent and often have competing interests. As such there was little desire to form any cohesive union. Hoewever, the expansion of the Hyperion League challenged this attitude. A more closely aligned policy, at least on economic matters, became tempting. The systems with the greatest interest in this coordination were the major worlds of Baixing and Tiffanye, and the high-tech worlds of Haapamaki and Nashua.
The Diadem Trade League grew out of the Diadem Trade Council, which was first established at Baixing in 984. The Council met every standard year at Baixing, accomplishing little from a policy standpoint, although its research staff compiled the Diadem Main Register, a study of trade and economic statistics for the worlds of the main.
The growing power of Hyperion led to renewed interest in at least discussing a more coordinated trade effort. The resulting Conference of Baixing in 1054 led to the formation of the Diadem Trade League, a strengthened organisation for coordinating internal and external trade policies.
