The main one is on TB's webpage, signifying its importance, but it and the others are here as well.

A Path Less Traveled (1864-1945) and The Path Goes On (1945-20??): An alternate America with the rise of a far different Green Party, statist Republicans and libertarian Democrats as well as a significant far-left movement, Filipino and Hispanic presidents, a seemingly permanent “New Deal Consensus” yet all three parties are divided regarding pressing social issues such as civil rights and LGBT rights.

Beautiful Nightmares: An universe with a bigger USA including Canada (that had a surviving CSA until the 1910s), a surviving British Empire (that turned to extreme racial mixing to keep it tied together), and other European empires still strong and somewhat thriving, this universe is very much a 19th century-punk world, with a “scramble” currently underway in space (although space is hard sci-fi), even though social (and economic?) issues has progressed on. This world may be beautiful in its uniqueness, but it's certainly a nightmare for many. (Intended to be less plausible and more 'fun')

Interesting Times: A new future history timeline focusing on the fate of the United States, including the resurgence of secessionism, the East becoming the region of great prosperity, Europe finally merging together as the European Federation and the resurrection of American Socialism and ultimately Fascism in a continent gone mad.

The Handmaid of Divinity: The tale of a vast space-empire (sometimes republic) called Symphonia that lasts exactly 20,000 years from its foundation to its demise. Political intrigue, cultural diversity and parliamentarianism dominates this story. Catgirls, vampires, witches, zombies, etc., all exist in a very weird universe that seems to have rejected the very laws of physics in some places…

The Power of Two: A somewhat light-hearted timeline that proposes the idea of all Presidents of the United States from 1901 onwards being OTL third-party candidates. From people as normal as John B. Anderson, as radical as Eugene V. Debs, as eccentric as Ross Perot or Henry Wallace, or as crazy as Lyndon LaRouche or John Hagelin, this timeline covers all their Presidencies and makes us thankful for third parties!

The Sapphire Crown: Set in a completely-fictional world (secretly set thousands of years in our future), it tells the tale of Safiria, a continent (or two? three?) with a history of being united under Empires, but by the 1920s, it was disunited for centuries. The tale of its re-unification and ultimately, its personal liberation covers a century, from the 1920s to the 2020s. Also, eternal 50s-punk.

Vive la Louisiane!: A very butterfly-free timeline covering the life of a surviving French Louisiana that got its independence in the 1810s and continued from there. From the Arctic ice-lands in the North to the hot and damp bayou, the Republic of Louisiana is a vast country, with its own successes and turmoils. From President William C. C. Claiborne all the way to Amanda Curtis today, the Republic has struggled, and thrived.
