Marvel Movie Timeline: A Complete History Of The MCU

The Inhumans and the Beginning of Hydra

Millennia ago, the blue-skinned race known as the Kree began to form a warlike empire. Around 5,000 years ago, the Kree began to travel the universe, experimenting on other races. Their goal was to create super-soldiers, who would serve as their greatest weapons. Although most of these experiments were unsuccessful, on Earth they succeeded in creating the Inhumans. The first Inhuman, Alveus, possessed the power to take control of other members of his race. He led an uprising against the Kree, driving them away from the planet. It's unclear quite how this happened, given the Kree actually believed the Inhumans had been rendered mostly extinct in the aftermath.

Humans and Inhumans alike feared the power of Alveus. They united to banish Alveus through a Kree Monolith, sending him to the planet Maveth. Alveus's disciples formed a secretive cult with the sole purpose of finding a way to bring him back to Earth; always seeking power, this cult would endure through the millennia, known as Hydra.

Tension grew between the humans and Inhumans, with humanity fearing their power. The bulk of the Inhumans chose to relocate to a Kree outpost on the Moon, which they dubbed "Attilan." There, the Inhumans established a strict caste system in order to control their population.

The Age of Asgard


In 2,988BC, the Dark Elves recognized that a cosmic event known as the Convergence would see the fabric of reality weakening. They sought to use the Reality Stone (which they called the Aether) to recreate their own universe of darkness. Fortunately, the Dark Elves were opposed by the forces of Asgard, under the leadership of Bor. When the dust settled, Bor thought he had committed genocide, wiping the Dark Elves out. Believing the Reality Stone to be too dangerous, he had it secreted away. Unknown to Bor, the last survivors of the Dark Elves – including their leader, Malekith – locked themselves in suspended animation, awaiting the next Convergence.

Bor would be succeeded by his son, Odin, who initially pursued an imperial policy. The forces of Asgard ransacked other worlds and civilizations, taking their treasures for themselves. Odin’s greatest warrior was his daughter, Hela, who cut a bloody swathe through all Asgard’s opponents. Finally, as the centuries passed, Odin began to believe he was leading Asgard in the wrong direction. He attempted to push Asgard towards a more benevolent policy, but was fiercely opposed by Hela. The All-Father ultimately banished his daughter, trapping her with his own might; it was a decision that cost Asgard dearly, as she briefly escaped and slaughtered Asgard’s famous Valkyrie warriors.

Odin may have renounced the old imperialism of Asgard, but he was still willing to intervene in galactic affairs. He led Asgard in defense of other realms, most notably Midgard (the Asgardian name for Earth). When King Laufey of Jotunheim invaded Midgard in approx. 1,000AD, the Asgardians intervened. The Frost Giants were driven back to Jotunheim, and their most powerful weapon – the Casket of Ancient Winters – was secreted away in Odin’s Vault. The All-Father stumbled upon a Frost Giant child, who he adopted as his own son in the hope he would become a bridge between the two races. Asgard would launch another campaign on Midgard in the 1300s, and one of their Berserker warriors would choose to desert. A century later, in 1409, Odin decided to hide the Tesseract with a group of worshipers in Tønsberg, Norway. It would remain hidden until the 20th Century.

The Fall of Titan

Another alien society developed upon the planet Titan, a rich and lush world. Population growth on Titan was explosive, not helped by the exceptional long lives of the world's inhabitants. One of Titan's philosophers, Thanos, game to believe that population growth was in danger of outstripping Titan's natural resources. He believed this would lead to a global catastrophe. Thanos's solution was an act of genocide, the proposed slaughter of half of Titan's population. "At random," he explained. "It would be fair, for rich and poor alike." This inhuman idea was dismissed by Titan's rulers, and Thanos was called a madman.

Tragically, Thanos's warning came to pass. Somehow, overuse of Titan's resources led to an extinction level event. Thanos, who had seen the disaster coming, was the sole survivor of Titan. As he looked out at the universe, Thanos realized he saw the same pattern repeating on a cosmic scale; everywhere he looked, life was flourishing, and consuming resources. Thanos would ultimately decide to apply his twisted philosophy to the rest of the cosmos.

It's impossible to accurately date the fall of Titan. All life on the world seems to have been consumed, and this may have even affected the planet's bacteria, meaning the normal process of decay no longer affects the planet. Thanos's exceptionally long life actually means this could actually have happened millennia ago.
