This article contains fan speculation. There is no solid evidence for or against some parts of this article.

Below is a timeline of events in the history of the Pokémon world, primarily those established in the canon of the Pokémon games, since these tend to also apply to other forms of canon. There is also a separate timeline of events for the anime series as well as one for Pokémon Adventures, both of which differ from that of the games.

There are many stories and legends surrounding the history of the Pokémon world. It is not entirely clear if these legends are true or not, but there are many hints in the series that suggest that they are.

Please note that the below timeline is based on both speculation and confirmed information from different aspects of the Pokémon franchise.

Timeline

The clash between Groudon and Kyogre as depicted in ancient paintings

Beginning of the Pokémon universe

This information is based primarily on the mythology of both the Hoenn and Sinnoh regions.

• In a vortex of complete chaos and nothingness, a single Egg comes into being, which then hatches into Arceus, the first being in existence. Arceus then creates time, space, and antimatter. Giratina, as punishment for its destructive nature, is sent by Arceus to live in the Distortion World. Dialga and Palkia then succeed in creating the universe and Pokémon world and retreat into their own dimensions afterwards, with a point of access being at the ancient Spear Pillar in Sinnoh.

• Arceus then creates Uxie, Mesprit, and Azelf, giving knowledge, emotion, and willpower to all living things that come into existence in the Pokémon world. The three dive into caves at the bottom of Lake Verity, Lake Valor, and Lake Acuity in Sinnoh, giving them the name "lake guardians".

• Kyogre is formed by the pressure in the deep sea trenches, Groudon is formed deep inside the Earth, likely from hardened magma and earth, and Rayquaza is formed by the minerals of the ozone layer. Rayquaza proceeds to fly around in the ozone layer, occasionally coming to rest at Sky Pillar.

• Kyogre and Groudon then proceed to fill the sea and create land, respectively. A chance meeting turns the two into rivals, and a conflict for dominance over the Pokémon world begins. This battle continues until Rayquaza quells it, causing Kyogre and Groudon to retreat to special caverns, where they rest until the events of Generation III many years later. The Red and Blue Orbs are created to prevent the reawakening of Kyogre and Groudon, and are left at Mt. Pyre for safekeeping. At this time, Mew may have been plentiful and lived in large numbers.

• Landmasses such as Mt. Coronet are created, and Regigigas moves the continents, forming the regions, and creates the three titans, Regirock, Regice, and Registeel, out of clay, ice, and magma, respectively.

• The Sinnoh region is created around Mt. Coronet. During this violent procedure, Stark Mountain is created due to shifts in the crust of the world and Heatran is formed in a pool of lava. Arceus creates the Adamant, Lustrous, and Griseous Orbs before falling into a deep slumber.

Prehistory

This information is based primarily on the study of Fossils and other archaeological remains. Some of this information is also based on scientific research.

Millions of years before Generation I:

• The earliest known prehistoric Pokémon existed at this time. It is possible that the Mew population may have decreased at this stage, as they slowly gave way to other Pokémon species. The first humans also appeared around this time.

• Anorith is stated to have existed in primordial seas, with its eight legs at some point developing into its known eight wings.

• 300 million years ago: An ancient version of Genesect was born. Kabuto and Kabutops lived in the sea.
  • Team Plasma later used Genesect's DNA to create an infinitely stronger version of it with cybernetic technology.

• An unspecified hundreds of millions of years ago: Carbink begins its undisturbed underground sleep after its birth. It was born from deep underground temperatures and pressures.

• 100 million years ago: Species such as Aerodactyl, Lileep, Cranidos, Shieldon, Tirtouga, Archen, Tyrantrum and Amaura were supposedly widespread. They all ultimately went extinct, but not before Archen gave rise to bird Pokémon and Tirtouga gave rise to turtle Pokémon.
  • A fossil is found millions of years later in Hoenn and revived scientifically by the Devon Corporation.
  • Shellder is known to be the prey of Omastar.
  • Carracosta and Archeops preyed on Omanyte. Only Carracosta is known to have eaten Omastar.

• Relicanth is said to have remained unchanged for over 100 million years.

• 20,000 years ago:
  • A meteorite containing Eternatus fell in the Galar region.
  • The first Claydol was brought to life from a clay doll.

• 10,000 years ago: During the last Ice Age, the Mamoswine population flourished, then decreased when the Ice Age ended.

• At some point in the distant past, the Magikarp population mutates due to unknown reasons and becomes weaker.

• At some point after the Iron Age, Regigigas is sealed away in the Snowpoint Temple, and Regirock, Regice and Registeel are sealed away at various points across the Hoenn region after years of human worship.

3,000 years before Generation V:

• The Relic items are created.

3,000 years before Generation VI:

AZ and the ultimate weapon

• The Kalos war occurred, the ultimate weapon was created underneath Geosenge Town, and AZ was given eternal life. This sets a chain of events into motion that leads to the discovery of Mega Evolution.

3,000 years before Generation VIII:

• A black storm called the Darkest Day occurred and was stopped by Zacian and Zamazenta.

2,500 years before Generation V:

2,000 years before Omega Ruby and Alpha Sapphire:

• Hoenn is plagued by meteor showers. A meteor turns the homeplace of the Draconid people into Meteor Falls.
• The world overflowed with natural energy which Groudon and Kyogre, in their primal forms, fought over. They ravaged the earth and were only calmed by Rayquaza after the Draconid people summoned it using a wish on a meteor at Meteor Falls. The people of Hoenn begin to revere Rayquaza as a savior.

1,500 years before Generation I:

• The earliest known system for writing is developed and used at the Ruins of Alph, Tanoby Ruins, and Solaceon Ruins. Archaeologists are currently unsure whether the nearly identical Unown preceded or succeeded the writing system, but it is assumed they share some sort of connection.
• The Farfetch'd population decreases due to overhunting.

c. 1,000-2,000 years before Pokémon Legends: Arceus (c. 1,300-2,300 years before Generation IV):

• An ancient society called the Celestica people lived in the Sinnoh region. They worshiped Arceus and built many structures which can still be found as ruins in the region in modern times, such as Solaceon Ruins, Snowpoint Temple, and Spear Pillar.

1,000 years before Omega Ruby and Alpha Sapphire:

• A thousand years after the events at Meteor Falls, a meteor struck Hoenn, creating Sootopolis City. Groudon and Kyogre reawakened to fight over the wellspring of primal energy which came from it. The people of Hoenn wished on Rayquaza to save them, and using the meteor, Rayquaza performed the world's first Mega Evolution and calmed the two. Sky Pillar was built in Rayquaza's honor, and the Draconid people promised to pass down the prophecy that in 1,000 years the meteor would return - causing the events of the Delta Episode.

800 years before X and Y:

• Xerneas released life energy throughout the Kalos region and fled to a forest, where it went to sleep in the form of a tree.
• Yveltal absorbed life energy throughout the Kalos region and fled to the mountains, where it went to sleep in the form of a cocoon.

In the first mystery, Victor/Gloria meets Calyrex, the former king of the Crown Tundra, and helps it reunite with its steed, Glastrier or Spectrier. In the second mystery, they investigate ruins scattered around the tundra, encountering and catching the Legendary titans. In the third mystery, Victor/Gloria pursues and catches the Galarian legendary birds across Galar. Upon solving these mysteries, Victor/Gloria finds a note describing a fourth mystery that Peony does not recall writing. Upon bringing it to the Max Lair, Victor/Gloria learns about Ultra Beasts and Necrozma, and is eventually able to catch Necrozma in a Dynamax Adventure.
  • After becoming Champion, Victor/Gloria and Hop stop the plans of Sordward and Shielbert, who cause chaos around the region in their misguided attempt to restore the Galarian monarchy. In the process, Victor/Gloria catches one of the two Legendary Pokémon of Galar, and Hop sets out to be a Pokémon Professor.
  • After resolving the incident with Sordward and Shielbert, Victor/Gloria returns to the Master Dojo, where they find Hop conducting research on Sonia's behalf. Mustard tells them that Urshifu hates the taste of Max Soup, so, in order for it to unlock its Gigantamax potential, a special ingredient is needed to make it drink the Max Soup. He doesn't reveal what this ingredient is, though, and leaves it to the duo to figure it out on their own. After a few bad guesses, Victor/Gloria and Hop travel to Honeycalm Island, where Victor/Gloria gets thrusted into a Max Raid Battle against a Dynamax Vespiquen. After defeating it, they find the missing ingredient: Max Honey. Upon returning to the dojo, Mustard informs Victor/Gloria that he wants to battle them in a no-holds-barred battle, where he uses his full power. In the battle, Mustard uses his own Gigantamax Urshifu. After being defeated, Mustard declares that he has nothing more to teach Victor/Gloria.
  • After the events of the incident with Sordward and Shielbert, The Isle of Armor, and The Crown Tundra, Victor/Gloria receives a call on their Rotom Phone from Leon, who invites them and many other strong Pokémon Trainers from Galar to a new type of competition called the Galarian Star Tournament (in which Trainers form duos and compete in Multi Battles) at Wyndon Stadium. Victor/Gloria partners with Hop or Marnie in the inaugural tournament, and emerges victorious after defeating Leon and Raihan (if their partner is Hop) or Raihan and Piers (if their partner is Marnie) in the finals, after which Leon announces that further Galarian Star Tournaments will occur.
