I have a fair few. Sadly I have a big enough problem updating my current timeline.
1) The Old World in the New: François Gaston de Lévis leads the French efforts in North America in place of Montcalm. With a saner campaign and a bit of luck the French are able to fend off the British onslaught. From there the development of the colony and its reactions to the tectonic forces shaping the rest of the world would become the focus of the TL.
2) A More Assertive Diem: Exactly as the title says, Diem takes greater pains to reel in the centrifugal forces of his family members, and establishes a more moderate and coherent regime than in OTL. Personalism gets a fairer shot at implementation and the window for coups is much smaller. Additionally, with how much familial politics it would entail it would presumably read like a medieval dynastic timeline, but with fighter jets and rock music.
3) 1837 Comes Early: In the immediate aftermath of the War of 1812, an anti-aristocrat revolt shakes the Canadas to their core, resulting in the disbandment of the Family Compact and Chateau Clique, the unification of the Canadas (or BNA, didn't decide yet on how big of a splash i wanted), implementation of responsible government, and economic reform of BNA decades ahead of time. Creating a Canada which is far more competitive with the USA.
4) An ""Honourable"" Defeat: The Italians are even less prepared and Conrad has shifted even more divisions over from the east. The Austro-Hungarians push all the way to the Adriatic coast, encircling much of the Italian forces at the Isonzo. When the Brusilov offensive guts the Central Powers in Galicia the war still ends in an Austrian defeat, but one from which a rump empire (the expected territories lost to Romania, Serbia, and Russia) is able to limp away from. Now it finds itself in the same neighbourhood as a revanchist Germany, an Italy which is out for blood, and hyperpower Russia. Fun times do not ensue.
5) A Dynasty of Sand, a Dynasty in the North, a Dynasty of Soda and Roaring Engines: Three PoDs with this one:
-In April of 1900 Rabih defeats a French column advancing on Kousséri, he orders his men to pursue, destroying the French force. From a prisoner he learns that the column, along with two others were meant to meet up at Kousséri. With this information and additional weapons captured from the defeated French he is able to defeat the French in detail, securing his state’s independence.
-In 1911 Samuel McLaughlin (senior partner) along with William C. Durant and Louis C. Chevrolet launch McLaughlin-Chevrolet (the American branch of The McLaughlin Motor Car Company Limited). Thus begins the McLaughlin Conglomerate.
-In 1912 negotiations between the Qing and the rebels break down as Tang Shaoyi is unable to extract guarantees of support for Yuan Shikai from Wu Tingfang. The Xinhai revolution continues, with Yuan Shikai and the Beiyang Army still “loyal” to the Qing.
