Building a historical knowledge graph with geospatial queryes

I’m building Erask, a temporal knowledge graph for exploring world history. It currently connects 90,000+ dated historical entries from ~4000 BC to today, using Wikidata, Wikipedia and geographic data. The goal is to explore relationships like: Empire → War → Battle → Person → Place → Event all synchronized across a graph, timeline and 3D globe. I’m also exploring a next step: letting users pin external web pages to the graph, turning Erask into a research layer over the web. Built independently with extensive AI-assisted development. erask.org
