Parallel: History Timeline

New: Ancient Rome comes as a free sample collection. There are now three ways to build one of your own, no file needed. Plus a new premium pack of 181 cities.

Who lived at the same time as Mozart, Van Gogh, or Napoleon?

Parallel lays out several timelines at once, and the connections that usually stay hidden appear at a glance.

It's your tool for assembling history around what interests you. Nine curated collections come built in, from the arts and sciences to rulers, empires, buildings, and the events that shaped history. They make it easy to start and give you a taste of what Parallel can do. The rest is yours to shape.

For the curious, for the classroom, for everyone who loves history.

WHAT YOU CAN DO • Swipe and zoom through the millennia, from antiquity to today. • Line up exactly the collections that fascinate you. • Highlight a person and see their contemporaries at a glance, while everything else fades into the background. • Open any entry for a clear, concise biography or summary, with a link to Wikipedia. • Follow a single thread through time, filtered by topic, place, era, and more. • Create your own collections and fill them with what matters to you.

Every built-in entry is carefully researched, historically grounded, and fact-checked.
