A heads up on the future of the polity known as the Sword Worlds from 1202 in the OTU. IYTU the future might not happen this way of course.
My summarization of what happens to the Sword Worlds Traveller 1248 SOURCEBOOK 3: THE SPINWARD STATES:
1208 The Darrian Confederation wanted a trade agreement with the occupied Sword Worlds. The Swordies would have nothing of it. The Darrians were sincere, forgive the history, don't forget it if you can't, let's trade. They pursued this for over 10 years before SW would listen. After even more talking a trade agreement is signed on the hosting world of Arden forming the League of Spinward States. It is more than a loose grouping and less than a confederation of Confederations. Arden likes it so much they sign up too. The Regency is still occupying the Sword World. The Regency DOES NOT like this turn of events. But
1209-1212 Regency Civil War
The Regency as a whole begins fighting the resurrected Vilani Imperium. No choice in the matter, the Vilani want territory. Fears at home of the spring up that Regency is going to become one unified government to combat the Vilani. The Zhodani had formed the Cronor Consulate 1208 and are starting to recontact Zhodani spinward. Then the Reformation Coalition shows up! It seems Virus is done and the reasons for a "Regency". Relatively bloodless because not enough ships are home to fight a full war. The Sword Worlds cannot free themselves though not for trying.
1229: The Imperial Regency, as it is now known goes off the deep end. The attempted recapture of Capital is called the Capital Bid. The Vilani and the Usdiki Trade Federation tried and failed. Capital is Viral Hell run by uploaded Lucan or uploaded Kkree depending on year. They should have learned.
1234: By the time Regency ruler Ciencia returns in 1234, Gram succeeds in independence (with full Darrian support!) and joins the SW. The SW finally gives full support to the League of Spinward States (remember them?). The Regency collapses due to the failed Capital bid The SW is fully free of Regency influence. Regina declares indepence and forms the Republic of Regina declares independence, joins the League of Spinward States as do other groups.
1235: The Metal Worlds free themselves of the Regency Remnant and become their own polity. Completely independent of the SW, they join the LSS. By the end, the LSS has enough strength in systems fleets. The Regency has more systems, but lost much of its fleets in the Capital Bid.
