 Founded in 2020

The Law Association for Crimes Across History, LACAH, is a non-profit and student-run project. So far, we have had 600+ 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.

Meet Our Executives

Joshua Zhang

Joshua Zhang ('23) is a senior at Shanghai American School and will attend Emory University this fall, intending to major in Philosophy, Politics, and Law. As head of the case team, he strives to bring LACAH tournaments accurate and professional mock trial case packets. A mock trial veteran that has either competed or organized for all iterations of LACAH, he also captains a national-level mock trial team and represented China in a team that ranked third in the world. Joshua doesn’t see mock trial as the end to his legal endeavours: his dream is to become a human rights lawyer and stand up for justice.
