Founded in 2020

The Law Association for Crimes Across History, LACAH, is a non-profit and student-run project. So far, we have had 450+ participants from 41+ countries compete at our tournaments. With cases themed around social justice, we hope to address current issues through studying history.

Our Mission

Our mission is to provide collaborative mock trial opportunities to high school students around the world to learn about the practice of law, develop empathy, study history with a legal lens, and build a global network of like-minded, proactive peers.

We aspire to make a positive impact on our generation's global outlook, provide a relevant truth-seeking experience, and create international interactions for all.

The first time any man's freedom is trodden on, we're all damaged.
