The questions that come up whenever you watch a period drama

Same Era, Different Worlds is a personal project that began with a question raised while watching historical films and series: what was happening elsewhere in the world at that moment? Textbooks teach Korean history and world history separately, but the actual past unfolded at the same time on a single axis. This site tries to show that simultaneity at a glance.

What can you do here

The timeline app lays out 37 films and series, 225 Korean, 144 world, and 102 Christian-history entries (biblical narrative and church history) side by side in chronological order. Click an event card and what was happening on the other side of the world is highlighted with it; directly related events, such as the Imjin War and Toyotomi's unification of Japan, are joined by arrows so the connection is immediately visible. You can also search by year or event name to jump straight to a period.

The four timelines go in any order

Film · World · Korea · Christianity — these four columns have no fixed sequence. Drag a column label, or move it with the ◀ ▶ buttons, to arrange them however you like, and uncheck any timeline you do not need. Putting the two timelines you want to compare next to each other is the best way to use this site: set film beside Korean history and 1597, the year of Roaring Currents, sits next to the second Japanese invasion; set it beside world history and the Edict of Nantes appears instead. On a narrow screen the columns are not split into tabs — you scroll them sideways, still side by side.

How are the films chosen and placed

Titles are placed by the year the story is set in, not the year of release. Noah sits in the primeval age, Gladiator in second-century Rome, Pachinko in the colonial period. Each entry carries a synopsis together with a note on critical reception, strengths and weaknesses, and historical accuracy; there is no numeric score. Streaming availability shifts often by date and country, so treat the platform field as indicative only.

Beyond the timeline, the articles section takes two eras and two regions and tells them together in prose. If the timeline is the data, the articles are the story.

Where does the data come from

The Korean timeline draws on the Korean History Chronicle published by the National Institute of Korean History, and the world timeline follows the scope of the South Korean high school world history curriculum. It is not a transcription of those sources but a study reference, summarized and rearranged so that a general reader watching a period drama can follow the context. Interpretations of particular events differ between sources and schools of thought, and nothing here claims to be the single scholarly consensus.

Who made it

The site was planned and built as a hobby by one person with an interest in history, and particularly in the comparative question of what was happening elsewhere at the same time. There is no team or company behind it; one person organized the data and built the interface. Advertising revenue covers the server and domain costs, and any time left over goes into steadily expanding the timeline data.
