The IACP is the longest-standing and largest law enforcement leadership professional organization in the world. It was started in 1893 by a group of approximately 50 police chiefs who met to share ideas on improving crime detection and prevention. From these humble roots, the IACP grew into an organization whose membership now includes individuals in more than 155 countries worldwide. Annually, the IACP manages more than 40 national- and international-level grants and cooperative agreement programs, in cooperation with the U.S. Departments of Justice, Transportation, and Homeland Security and the State Department, in addition to grants from the Laura and John Arnold Foundation, John D. and Catherine T. MacArthur Foundation, the Motorola Foundation, and Bloomberg Philanthropies.
