The the main site is still English only unfortunately, and development is currently focused on on our timeline engine (HistropediaJS). This is our first revenue stream, so we’re just building it up to the stage where we can sustain ongoing development of the main site as well.

We do however have a separate tool that can display timelines in other languages using live data from Wikidata data:
http://histropedia.com/showcase/wikidata-viewer.html

Here’s an example timeline:
Items within 3km of Rome city centre (in Italian) – https://tinyurl.com/y8j8sp6l

Unfortunately this tool uses Wikidata queries so you would need to learn the syntax before being able to write your own.

But it’s very easy to edit existing queries to change the language of the output. Let us know if you need help getting started!
