The Scottish Coalition USA, COSCA, and the History of Tartan Day in the United States

The establishment and national recognition of Tartan Day in the United States represents a defining achievement in the celebration of Scottish heritage across the American diaspora. At the heart of this accomplishment was the formation of the Scottish Coalition USA (TSCUSA), a unified alliance of leading Scottish American organizations—among them the Council of Scottish Clans and Associations (COSCA)—which came together with a shared purpose: to secure formal national recognition for Tartan Day and ensure its place within the American cultural calendar.

As a longstanding representative body for Scottish clan societies and heritage organizations, COSCA played a key role within this collective effort. Bringing both national reach and deep-rooted connections across the clan community, COSCA contributed to the coordinated advocacy that ultimately led to the successful recognition of Tartan Day at the federal level.

From Collective Advocacy to National Recognition

TSCUSA was established to unify voices across the Scottish American community and to provide a structured, collaborative approach to national advocacy. Through this coalition, organizations such as COSCA helped amplify the significance of Scottish heritage within the United States, demonstrating both its historical impact and its continued cultural relevance. TSCUSA formed in the late 90's, specifically to lobby Congress for the creation of national holiday recognizing the many contributions of Scots, and Scottish Americans, to the foundation and subsequent development of the United States, in all fields of endeavor.

The US Senate passed the first Tartan Day Resolution in 1998, sponsored by Senator Trent Lott of MS. On the recommendation of TSCUSA, the Senate Resolution selected April 6 each year as the date for celebrating the holiday, based on the fact that that was the day on which the Declaration of Arbroath, the Scottish Declaration of Independence from the English crown, was signed and issued in 1320.

The House of Representatives followed several years later on March 9, 2005 when it unanimously adopted House Resolution 41, formally designating April 6 of each year as “National Tartan Day,” sponsored by Rep. John Duncan of Tennessee. A unified effort culminating an achievement that not only reflected congressional support, but also the success of sustained, coordinated advocacy led by TSCUSA and its member organizations.

Subsequent to the passage of the House Resolution, the House created its own Friends of Scotland Caucus, sponsored by Congressman Mike McIntyre of North Carolina and Congressman John Duncan. TSCUSA worked closely with the House Caucus for over 20 years from the time of its creation, co-sponsoring symposia and receptions on the Capitol grounds, on or near Tartan Day, for the next 20+ years.  COSCA was actively involved at every stage.

Tartan Day is now an established part of the national commemorative landscape.

A Collaborative Coalition

The strength of the Scottish Coalition USA lies in its member organizations, which together represent the breadth and diversity of the Scottish American community. These include:

  • American-Scottish Foundation (ASF)

  • Association of Scottish Games & Festivals (ASGF)

  • Council of Scottish Clans and Associations (COSCA)

  • Scottish-American Military Society (SAMS)

  • Scottish Heritage USA (SHUSA)

  • Tartan Day West

  • Tartan Day South

  • Scottish American Women’s Society (SAWS)

Each organization brings its own expertise, networks, and community engagement, contributing to a unified national voice that has been essential to both the recognition and continued success of Tartan Day.

COSCA’s Role in a National Movement

COSCA’s involvement in TSCUSA reflects its broader mission to support, connect, and strengthen Scottish clan societies and heritage organizations throughout the United States. By contributing to the establishment of Tartan Day as a nationally recognized observance, COSCA has helped create a platform through which clans and affiliated groups can collectively express and celebrate Scottish identity.

Today, Tartan Day is observed across the country—from San Diego and Charlotte to Washington, DC, and New York City—through parades, cultural events, educational initiatives, and community gatherings. These celebrations provide an opportunity for COSCA member organizations to engage the public, foster connections, and promote a deeper understanding of Scotland’s historical and cultural legacy.

A Continuing Leadership Role

The success of Tartan Day underscores the importance of collaboration within the diaspora, and COSCA remains central to this ongoing effort. As both a founding participant in TSCUSA and a leading voice within the clan community, COSCA continues to support the evolution and relevance of Tartan Day in the twenty-first century.

Through its work, COSCA not only helps sustain this national observance but also ensures that it remains grounded in authentic heritage, meaningful engagement, and a strong sense of shared identity.

Looking Forward

Tartan Day stands today as a testament to what can be achieved through collective action. The role of COSCA within the Scottish Coalition USA highlights the enduring importance of leadership, partnership, and vision in advancing the recognition of Scottish heritage in America.

As the observance continues to grow, COSCA remains committed to supporting its member societies and strengthening the connections that unite the Scottish diaspora—ensuring that Tartan Day continues to inspire, educate, and connect communities for generations to come.
