The civilization known commonly as "The Progenitors" discovers a technology left behind by an even more andient unknown people. It has the power to create life, among othr things. Because the Progenitors are completely alone in their part of the galaxy, they deposit specially coded DNA material on many worlds to guide evolution in order to create a highly diverse network of life across the galaxy. Embedded in this DNA is a message about diversity. Eventually they go extinct, but they leave an entity behind to represent them to future explorer who discover their work (Gambit; Life, Itself)

An alien race, from far away in the Delta Quadrant, makes the first of several visits to Earth, taking over two generations for the trip each way. They discover a primitive civilization living on glacial ice fields. The aliens give "a genetic heritage" to the primitive humans, and leave, returning several times over the centuries.

In order to hide the fact that the shapechangers are behind the Jem'Haddar, they declare an empire they name "The Dominion" and fade into a shadowy myth of the "Founders." The Dominion, does not attempt to impose government on individual planets, but begins a slow process of working to control commerce and militarization between worlds.

The T'Rogorands come into repeated conflict with the Jem'Haddar of The Dominion, which is still building its influence. 

In the Delta Quadrant, an expedition of the Naceen species, from another galaxy, accidentally damages the ecosystem of Ocampa. They guide the humanoid Ocampa natives into an underground refuge, and provide all of the water, food and power the Ocampa need. Two Caretakers, a male and a female, are left behind to permanently fulfill the debt to the Ocampa. The Ocampa people typically live only 9 standard years, then transform into energy beings. A standard generation is considered to be two years. The Ocampa species is telepathic, but loses much of this ability over the next 1,000 years, due to disuse.  (The Caretaker, et al) 

According to legend, Klingon warriors kill the gods of the Klingon people, because they have become too troublesome. This may also be the result of the gods not protecting them from the invading Hurk. 

A group of Vulcans, later called "Romulans" by the Federation, oppose the teaching of logic by Surak. They leave Vulcan with the goal of establishing their culture on a new world. The Romulans are "written out" of Vulcan history by the followers of Surak, and later generations do not learn of them.  (Balance of Terror, et al) Due to their sublight ships, the Romulans make several stops on habitable worlds along the way before they finally settle in the double star system designated Romulus/Remus by the Federation, in sector Z-6. Their new planet, also known as Romulus, is considered to be by far the most beautiful of the worlds they had visited. One faction of the spacefarers, known as the D'Brun, separates from the main body of the former Vulcans, remains in space and constructs small outposts on several worlds. 

At some point, a sect of warrior nuns forms within the Romulan culture, the Qowat Milat, which practices absolute candor and champions lost causes.

Hidden deeply within the Romulan culture is the Zhat Vash , an organization that holds a deep antagonism toward artificial inteligence. (Maps and Legends). While exploring a unique eight-star system in the Vayt sector, which they call the Eightfold Stars, because it appeares to be artificial, they discover the psychic records of an ancient 200,000+ year old civilization that was destroyed by an unknown force after their artificial intelligence achieved a certain level, known as the legeld of Ganmadan. The psychic signal is so powerful that it drives many who receive it mad. The Zhat Vash vows to never let such a thing happen again (Broken Pieces).

The sun of the star system the Romulans select for settlement is already showing hints of going supernova, which will happen a millennium in the future. Maybe the Romulans did not notice this because they are more warriors than scientists. Somehow their new planet avoids the scorching radiation and solar flares that are common before a supernova. Romulus, indeed, is considered to be a beautiful world (Star Trek, Picard).

On Vulcan, as the prominence of logic grows, war subsides, great strides are made in technology and space flight, however as the centuries pass, more and more emphasis is placed on ethical and moral development of the species. 

Last celebration of the Vulcan pagan festival of Rumery. 

One or more Bajoran "light sail" ships leave the Bajoran system, and visit Cardassia, and possibly other worlds. The ships are accidentally accelerated to warp speeds by a tachyon stream near the Denorious belt. How the ships survive the acceleration without a warp field or inertial compensators is unknown. At least one Bajoran ship crashes on Cardassia. Similar ships are used for the next seven centuries, at least.

Famed poet John Keats is born, in England. (Historical Reports) 

The British sailing fleet, commanded by Lord Admiral Nelson, destroys the joint fleets of France and Spain in a clash known as the "Battle of Trafalgar." On the night before the battle, Nelson tours his flagship, the HMS Victory, under the impression that it may be a hopeless battle. The British fleet, however, is victorious and Nelson dies gloriously, knowing that the battle is won. Although the British win, Napoleon honors French Navy Captain Picard for valor. 

The defeat at Trafalgar leaves Britain in a commanding position on the high seas, able to attack the coast of Napoleonic France at will. The French public is not told about the seriousness of the defeat, and the war continues until 1814, when Napoleon surrenders. He returns to power nine months later, and is ultimately defeated at Waterloo by forces under Wellington in 1815. Pursued by his own French people, as well as most other nations, he surrenders to British forces aboard the HMS Bellerophon at Plymouth, and dies in 1821, of cancer, possibly complicated by exposure to arsenic fumes, on St. Helena. (Historical Reports) 

Famed English poet John Keats dies, at age 26, the victim of an entity calling itself Anaya, possessing the ability to stimulate bioelectric fields in the brain in order to feed off the creativity. This stimulation, if carried out long enough, is fatal, and Anaya has the ability to travel at warp speeds, without benefit of spacecraft, so roams the galaxy in search of creativity.

The Watcher is Tallinn, who looks just like Picard's future housekeeper Laris. Tallinn is sent by The Travelers, including Wesley Crusher, who are the people who sent Gary Seven in the 1960s.  The timeline change is whether Renee Picard goes on a manned mission to Europa.  Not going triggers a chain of events in which Earth becomes a xenophobic authoritarian society.  By the skin of their teeth, Picard and friends manage to get Renee onto the ship and into space, but Tallinn dies, her final act in protecting Renee. In exchange for saving the life of Seven of Nine, the borg queen, who has joined with Agnes Juratti, takes La Sirena and heads for the Delta Quadrant, where the Borg of 2024 are.

Rios elects to stay behind in 2024 with the beautiful Dr Teresa and her son Ricardo.As an adult, Ricardo will lead a braintrust that figures out how to use that microorgnism to clean the water and the air, easing or ending Climate Change (at least until the future nuclear war).

In Jupiter space, Renee discovers a possibly sentient microorganism on Io. Rios and Teresa lead humanitarin programs around the world.

In every major American city, "Sanctuary" districts exist, in which homeless people live. The areas have minimal security, health and welfare services, with thousands of people crowded into a small area. In San Francisco, 10,000 people live in a 20 square block area. People enter the Sanctuary district on the promise of help finding jobs, but government workers are unable to locate jobs in anywhere near sufficient quantities.Benjamin Sisko, Julian Bashir and Jadzia Dax appear in San Francisco as the result of a transporter time-travel accident in the year 2370. Sisko and Bashir are picked up by authorities, and taken to Sanctuary district A, because they have no papers. Dax obtains papers and searches for her friends. In a street fight, Gabriel Bell is killed, helping Sisko and Bashir defend themselves. Sisko realizes that history says Bell will be instrumental in later events.On September first, residents of San Francisco Sanctuary District A riot, to protest the lack of jobs. Six government workers in the Sanctuary Processing Center are taken hostage by Bittle "B.C." Courage and his followers. Lengthy negotiations begin, lead by Sisko posing as Gabriel Bell, and Michael Web, seeking closing of the Sanctuary Districts, and reinstatement of the National Employment Act. Although access to the computer nets are cut off by police, the residents hack access, and present a series of pleas for jobs by reasonable-sounding internees, as millions of people watch.On the orders of Governor Chandler, however, National Guard troops storm the Sanctuary district, freeing the hostages and killing many residents guarding the hostages, including Web and B.C. Sisko is wounded protecting the hostages, but escapes. A grateful former hostage plants Bell's ID card on a corpse, so history can record his death.   Sisko, Bashir and Dax are recovered to the year 2371 by Kira and O'Brien. 

The investigation of the Sanctuary riots triggers a major reform movement, and begins the steps toward eliminating want and homelessness.

Opposing military juntas conduct a limited nuclear war on Earth, later called World War Three (and possibly Colonel Green's War), Due to muched up timelines, this war also includes the eugnics wars, causing nuclear devastation in some areas.600 million people die. After the war, civilians temporarily control the military with drugs. Recovery from the war is rapid. Limited space travel resumes quickly with spacecraft and personnel which had remained in space. Large tracts of land on Earth are dedicated to park land. (Encounter at Farpoint) The war is observed by the Sky Spirits who find no remnant of the Inheritors. They conclude that humans are violent, and have no respect for the land.
