The essentials in 30 seconds: the MCU story does not unfold in the films' release order. Following the internal chronology of events makes everything clear: from Captain America's origins in the 1940s to today's Doomsday era, passing through the birth of the Avengers, the war against Thanos, and the chaos of the Multiverse. This guide simplifies the timeline into five major eras, without unnecessary spoilers.
When discovering the Marvel universe, one question keeps coming up: what is the actual order in which the story unfolds? There is a significant difference between the release order of films in theaters and the chronological order of events within the universe. Iron Man (2008) launched the saga in theaters, but the MCU story begins much earlier, in the trenches of World War II with Captain America.
Rather than providing an exhaustive film-by-film list (which you can find in our complete guide to the MCU in chronological order), this article offers a simplified overview by major era, designed for beginners who want to understand the overall structure without getting lost in the details.
Chronological Order or Release Order: What's the Difference?
Release order refers to the date each film or series arrived in theaters or on streaming. Chronological order, on the other hand, refers to when the events take place within the story, regardless of their actual release date. The two orders sometimes overlap, but often diverge: Captain America: First Avenger (released in 2011) tells the story of events in the 1940s, long before Iron Man (released in 2008), which takes place in 2010.
This distinction explains why some fans prefer watching the films in chronological order for continuous narrative immersion, while others follow the release order to experience the revelations and surprises as the studios originally intended. Both approaches are valid: this guide simply helps you understand the chronological storyline and find your bearings, whatever your viewing order.
The Five Major Eras of the MCU Timeline
To simplify a timeline that now spans dozens of films and series, we have grouped the events into five major eras. This is the structure we will explore in the rest of the article.
| Era | In-Story Period | Key Events |
|---|---|---|
| The Origins | 1940s to 1990s | Captain America, Captain Marvel, the Early Days of SHIELD |
| The Birth of the Avengers | 2008 to 2012 | Iron Man, Thor, Hulk, the Formation of the Team |
| The War Against Thanos | 2012 to 2018 | Ultron, Civil War, the Quest for the Infinity Stones |
| The Snap, the Blip, and Endgame | 2018 to 2023 | The Disappearance of Half the Universe, the Return, the Final Victory |
| The Multiverse Era | 2023 to the Present | The TVA, New Threats, Avengers Doomsday |
The Origins: From the 1940s to the Eve of Iron Man
It all begins during World War II, when Steve Rogers becomes Captain America thanks to the super-soldier serum. This is also the period when the first traces of extraterrestrial technology appear, later influencing the entire universe, particularly through the Infinity Stones. In the following decades, organizations such as SHIELD take shape behind the scenes, laying the foundations for a world still unaware of the existence of superheroes. Carol Danvers, also known as Captain Marvel, also enters the scene during the 1990s, amid a cosmic conflict involving the Kree and the Skrulls.
This foundational period explains many narrative elements that only fully make sense later in the saga. To explore this foundation further, our article on the Infinity Stones explained details the origin of these artifacts, which span the entire timeline.
2008–2012: The Birth of the Avengers
The modern MCU story begins in 2010 within the internal continuity (even though the film Iron Man was released in 2008), when Tony Stark publicly reveals his superhero identity. Thor, from Asgard, then appears, followed by Bruce Banner’s transformation into Hulk, and finally the official formation of the Avengers to repel Loki’s invasion and the Chitauri army above New York. This founding battle, often called the Battle of New York, marks the moment when the entire world discovers the existence of superheroes.
Why This Period Remains a Good Starting Point
Many new fans choose to start directly with this era rather than with the origins of the 1940s, as it introduces the team as it is generally known, without requiring any prior knowledge. It is also the era most represented in collectibles, particularly Avengers posters depicting the team’s first gatherings.

After the victory over Loki, a new threat emerges in the background: Thanos, determined to gather the six Infinity Stones to carry out his plan. During this period, the AI Ultron nearly destroys the Avengers from within, the group splits during the civil war between Iron Man and Captain America, and new heroes gradually join the universe, such as Spider-Man, Doctor Strange and Black Panther. Each of these individual stories often prepares, without knowing it, for the final confrontation with the Mad Titan.
This era also sees the universe expand considerably on a cosmic scale, with the arrival of the Guardians of the Galaxy and the discovery that the threat does not come only from Earth. To understand the origins of this central antagonist, read our article on Thanos's Snap and What Really Happened.

This is the most dramatic era in the entire timeline. Thanos gathers the six Infinity Stones and makes half of all life in the universe disappear with a snap of his fingers, an event the survivors call the Blip. For five years in-story, the world attempts to rebuild amid the chaos, until the remaining Avengers find a way to travel through time and undo the catastrophe. The final battle that follows remains, to this day, one of the most memorable confrontations in the entire saga.
This period also ushers in a new generation of heroes poised to take over, such as Sam Wilson, who became the new Captain America, and Kate Bishop alongside Clint Barton. The repercussions of the Blip also continue to be felt across several series, making it an essential narrative turning point to understand.

View product2023 to present: the Multiverse and Doomsday era
The most recent timeline introduces a completely new concept: the Multiverse, the idea that there is not just one reality but an infinite number of parallel universes. The TVA (Time Variance Authority) theoretically oversees the stability of these timelines, until its own organization falls apart. This narrative opening allows new characters from other realities to be introduced, including variants of well-known villains, and paves the way for the saga's next major confrontations, particularly those involving Doctor Doom.
How to follow this period without getting lost
Since this era is still being written, it is also the most complex for newcomers to understand. Our dedicated article on the Marvel Multiverse Explained Simply lays out the essential foundations, while our analysis of the TVA and the Time Variance Authority explains how this key organization works.
Chronological order vs. release order: which viewing order should you choose?
There is no right or wrong method, but here are some guidelines to help you choose based on your viewing profile.
- Discovering the MCU for the first time? Release order is still recommended: it matches the way the studios designed the reveals and surprise effects.
- Already familiar with the main outlines of the story? Rewatching in chronological order lets you appreciate the narrative coherence from a new perspective.
- Want to introduce someone close to you to the Marvel universe? Start with the best-known films from the birth of the Avengers, which are more accessible than the origins of the 1940s.

Frequently Asked Questions
What is the difference between the MCU phases and the MCU timeline?
The phases represent a production and release structure decided by Marvel Studios. The timeline, on the other hand, corresponds to the order in which events actually take place within the story. A Phase 4 film can perfectly well depict events that occurred before a Phase 1 film. Find the full details in our article on the 6 MCU Phases Explained.
Which movie should I start with if I'm discovering the MCU?
Most fans recommend starting with Iron Man (2008), which launched the saga in theaters and remains the most accessible entry point, even though it does not correspond to the very beginning of the internal timeline.
Did the Blip really last five years?
Yes, in the MCU's internal timeline, five years passed between the disappearance of half the universe and the victims' return during the final battle against Thanos.
Do you need to have watched all the series to understand the current timeline?
It isn't mandatory, but some series, such as those centered on the TVA, provide important context for the Multiverse era. However, they are not essential for following the main story.
Where does Avengers Doomsday fit in the timeline?
Avengers Doomsday takes place in the most recent era of the timeline, after the events connected to the Multiverse and the TVA, and marks a major new chapter for the saga as a whole.
