Prior to 250 Spock's ancestors adopt a ceremonial ground that remains in their family at least until the 23rd century (TOS: "Amok Time").
Around 250 The inhabitants of Vulcan engage in terrible and destructive wars, a result of the violent passions and emotions that govern the Vulcan people. It is a savage time, even by Earth standards. Myths from this period describe a terrifying weapon of war called the Stone of Gol, that kills with the power of the mind (TOS: "Balance of Terror", "Amok Time", "All Our Yesterdays", TNG: "Gambit").Around 250 Surak leads the Vulcan people on a path of peace and logic. His writings are collected in an artifact called Kir'Shara. His katra will be preserved in a special vessel (TOS: "Amok Time", "The Savage Curtain", "Star Trek II", TNG: "Gambit", ENT: "The Forge", "The Awakening", "Kir'Shara").
In ENT: "The Forge", "The Awakening" and "Kir'Shara" the time of Surak is consistently set 1800 years before the episode. It is also shown that the devastating wars on Vulcan took place during Surak's lifetime. We may ignore the (by Vulcan standards) small inaccuracy of +/- 50 years. The date 100 years would exactly coincide with the supposed departure of the Romulans from the planet, but the latter must have happened later.
Around 250 The society on planet 892-IV evolves on a path similar to that of Earth and develops a culture similar to Earth's ancient Rome, a remarkable example of Hodgkin's Law of parallel planet development (TOS: "Bread and Circuses").
Around 360 Dissenters who don't agree with Surak's principles of logic have left Vulcan. They settle on various planets, including Calder II, Dessica II, Draken IV, Yadalla Prime and Barradas III, the latter being the home of the Debrune civilization. They will later be known as the Romulans (TOS: "Balance of Terror", "The Enterprise Incident", TNG: "Unification", "Gambit").

Prior to 870 The people of Kaelon II introduce the custom of the Resolution, a ceremony in which individuals commit suicide at the age of 60 to avoid being a burden to their society (TNG: "Half a Life").
Around 870 A war breaks out on Solais IV, which will last until the 24th century (TNG: "Loud as a Whisper").
Kahless defeats the tyrant Molor and unites the Klingons. He fights
with his brother Morath for twelve days and nights, when Morath has brought dishonor to his family. Kahless creates the first bat'leth. At the end of his
life, he points to a star in the sky and tells his people to look for him there.
(TNG: "Reunion"., "Birthright", "Rightful Heir",
DS9: "The Sword of Kahless").
The statement from "Rightful Heir" is that the Klingons have been waiting for the return of Kahless for 15 centuries. On the other hand, in DS9: "Soldiers of the Empire", Worf makes this logbook entry: "Rotarran Combat Log: The fifty-third day in the year of Kahless 999. We have reached the Cardassian border and begun our search for
the B'Moth." Maybe the 1500 years refer to human years, while Klingon years are 50% longer.

Around 1371 A group of humanoid space travelers are stranded in the Gamma Quadrant, on an interdimensional planet they call Meridian (DS9: "Meridian").
Around 1371 A group of explorers from another galaxy, the Nacene, visit the Ocampa homeworld in the Delta Quadrant where their technology causes an ecological disaster, leaving the planet as a desert. Two of the Nacene stay behind to take care of the Ocampa (VOY: "Caretaker").
Around 1372 The Klingon homeworld is raided by race called the Hur'q who steal the Sword of Kahless (DS9: "The Sword of Kahless").
Around 1372 The hedonistic festival of Rumarie ceases to be observed on Vulcan (VOY: "Meld").

Centuries ago The inhabitants of Thasus still have bodies of solid matter, but slowly evolve to forms of pure energy (TOS: "Charlie X").
Centuries ago The ruling family of the Ramatis star system is discovered to lack the gene required for the sense of hearing. A system is developed where a "chorus" of interpreters both hear and speak for members of the ruling family (TNG: "Loud as a Whisper").
Centuries ago The people of Ardana build a magnificent city, Stratos, in the clouds (TOS: "The Cloud-Minders").

Around 1669 Guinan's father is born (TNG: "Rascals").
1692 Xavier Maribona-Picard, an ancestor of Jean-Luc Picard, takes part in the suppression of the Pueblo Revolt of Native Americans (TNG: "Journey's End").
18th century A group of alien anthropologists known as the Preservers relocate American Indians to another planet to preserve them from extinction (TOS: "The Paradise Syndrome").
Prior to 1770 Sandrine's Bar opens in Marseille, France (VOY: "The Cloud").
Around 1770 The war between Eminiar VII and Vendikar begins. To avoid the mutual destruction of their civilizations, the two parties later agree on computer simulated attacks upon which the calculated victims are to report to disintegration chambers (TOS: "A Taste of Armageddon").
Around 1770 The two moons of Peliar Zel are colonized and will subsequently engage in hostilities that last until the 24th century (TNG: "The Host").
Around 1770 Hundreds of condemned criminals from the star system Ux-Mal are imprisoned on a moon of the planet Mab-Bu VI, where their consciousnesses will separate from their bodies some unknown time later (TNG: "Power Play").
After spending around 1500 years to rebuild their society, Vulcans build first
starships to explore the stars (ENT: "The Forge").
Actually, 1500 years after Surak would be rather around 1750. On the other hand, going exactly with the dates from "The Forge" would give us 1850. Since it was never meant to be an accurate statement, taking the average seems appropriate.
1821 Writer John Keats dies in Rome on Earth. Much of his work has been inspired by a non-corporeal entity called Onaya (DS9: "The Muse").
Around 1850 The Suliban homeworld becomes uninhabitable. As nomads, Suliban begin to settle down in many other star systems (ENT: "Detained").
Around 1850 The last of several wars between the Denobulans and Antarans takes place, leaving 20 million Antarans dead and leading to centuries of mistrust and hatred (ENT: "The Breach").

1937 Over 300 humans, including aviator Amelia Earhart and her navigator Fred Noonan who disappear over the Pacific Ocean, are abducted by an alien race called the Briori to the Delta Quadrant. Later, a revolt of the humans succeeds, but the ship that could have taken them home is destroyed (VOY: "The 37's").1947 In July of this year, a Ferengi shuttle crashes near Roswell, New Mexico. The passengers are taken prisoners by the US military, but they manage to escape. Official government records deny the existence of the aliens and their spacecraft (DS9: "Little Green Men").
1957 While observing the launch of Sputnik, a Vulcan ship crashes on Earth, costing one fatality. The survivors are eventually retrieved by another Vulcan ship, but one of them, Mestral, decides to stay on Earth where he will live the rest of his life unnoticed (ENT: "Carbon Creek").
Around 1966 Scientists on Miri's planet begin a "life prolongation project," creating a virus intended to halt the aging process. The project is a disaster and results in the deaths of all the adults on the planet. The children survive, aging at a reduced rate, although the virus causes their death upon entering puberty (TOS: "Miri").
