World History Commons

Teaming up with a leading educator, we design and implement tools that teach critical thinking.

An open educational resource with peer-reviewed content for world and global history teachers, scholars, and students. This website provides more than 1,700 annotated primary sources, 100 teaching guides, 30 overviews of methods and approaches, and 250 website reviews. World History Commons has four sections: Sources, Teaching, Methods, and Reviews. Each section can be filtered by region, time period, and subject. Every resource is also tagged to make it easy to find similar materials on any topic.
