The United States will commemorate its 250th (or “Semiquincentennial”) anniversary in 2026. AASLH is providing key leadership for the history community as we all prepare for this once-in-a-generation opportunity. We are monitoring national, regional, and state commemoration plans as they develop, serving as a clearinghouse of information for history organizations and practitioners at the local, state, and national levels. We are publishing resources to help guide commemoration planning, like webinars, blog posts, and other publications. We are in communication with other national initiatives, including the U.S. Semiquincentennial Commission, to help ensure that the values and goals of the history community are represented well in national commemoration efforts. We have organized a national coordinating committee, facilitating communication and collaboration among major organizations, institutions, and agencies. Finally, we are outlining major goals and themes for the anniversary that can help align the work of a diverse and dynamic field over the next several years.

In 2018, as early preparations for the Semiquincentennial began to take shape, AASLH began working with a dedicated group of volunteers to generate several broad aspirations for what the 250th anniversary can accomplish for the field and for the public. In addition to working directly with a group of volunteers, we also held listening sessions at several national conferences—including AASLH, National Council on Public History, Association of African American Museums, and the Association of Tribal Archives, Libraries, and Museums—to help ensure these goals spoke to the needs of our field. These goals, outlined below, helped to guide early planning by the U.S. Semiquincentennial Commission and other stakeholders, and several of the ideas generated in this project were included in the Commission’s Inspiring the American Spirit report detailing their vision for the commemoration.

As 250th planning shifts into a new, more public-facing phase, AASH will continue to update our goals so they most appropriately speak to the needs of our field and the current moment.
