The ACLS Humanities Program in Belarus, Russia, and Ukraine (HP BRU) was established in academic year 1998-99 with funding from Carnegie Corporation of New York. The principal activity was distribution of grants to individuals in these three countries to support humanities scholars doing exemplary work in the former Soviet Union during a time of crisis. ACLS worked closely with scholars in the region who represent a variety of disciplines: they advised on program design and helped distribute publicity and review applications. The review process included prescreening by scholars in the United States. Final decisions on awards were made by the Selection Committee.

The program’s mission was to ensure continued leadership in the humanities in the former Soviet Union through direct support to individuals doing exemplary work. In 2007, the Carnegie Corporation and ACLS, helped advisers to the Humanities Program found the International Association for the Humanities (IAH) as an independent organization of humanities scholars primarily in Belarus, Russia, and Ukraine to act as a bridge between the post-Soviet region and the worldwide scholarly community.  In 2010-11 and 2011-12 IAH conducted competitions for short-term grants on the model of the ACLS Humanities Program.

In the 12 years of the program, 743 awards were made for project grants and publication in humanities fields.

The Humanities Program in Belarus, Russia, and Ukraine also organized a dozen annual meetings in the region, modeled on the annual meetings of ACLS Member Societies. The location of regional meetings was moved across international borders and institutions to reach as many academic communities as possible.
