What was happening in China while the Byzantine Empire existed? Which civilizations were contemporaries of the Maya, Aztecs, and Inca?
I built Parallel Worlds — an interactive comparative timeline that brings 62 historical tracks across societies, states, archaeological cultures, and religious traditions, 217 periods, and 161 milestones onto one shared axis.
Search the record, filter by region, select a year, compare contemporaries, and open detailed historical cards. The site is available in Russian, English, and Simplified Chinese.
