Woodrow Wilson said of the Scots, "Every line of strength in American history is a line colored with Scottish blood."
The contribution of the immigrant Scots upon North America is massive and these people have remained proud of their heritage.
Numerous groups and societies throughout Canada and America have taken the anniversary of the Declaration of Arbroath (1320) as their national date to celebrate their Scottish roots.
On December 19th 1991, in response to action initiated by the Clans & Scottish Societies of Canada, the Ontario Legislature passed a resolution proclaiming April 6th as Tartan Day, following the example of other Canadian provinces.
America followed suit on March 20th 1998, when Senate Resolution 155 (S.Res. 155), proposed by US Senate Republican majority leader Trent Lott, was passed unanimously.
The resolution, with its preamble, is as follows:
S. Res. 155
Whereas April 6 has a special significance for all Americans, and especially those Americans of Scottish descent, because the Declaration of Arbroath, the Scottish Declaration of Independence, was signed on April 6, 1320 and the American Declaration of Independence was modeled on that inspirational document;
Whereas this resolution honors the major role that Scottish Americans played in the founding of this Nation, such as the fact that almost half of the signers of the Declaration of Independence were of Scottish descent, the Governors in 9 of the original 13 States were of Scottish ancestry, Scottish Americans successfully helped shape this country in its formative years and guide this Nation through its most troubled times;
Whereas this resolution recognizes the monumental achievements and invaluable contributions made by Scottish Americans that have led to America's preeminence in the fields of science, technology, medicine, government, politics, economics, architecture, literature, media, and visual and performing arts;
Whereas this resolution commends the more than 200 organizations throughout the United States that honor Scottish heritage, tradition, and culture, representing the hundreds of thousands of Americans of Scottish descent, residing in every State, who already have made the observance of Tartan Day on April 6 a success;
Whereas these numerous individuals, clans, societies, clubs, and fraternal organizations do not let the great contributions of the Scottish people go unnoticed:
Now, therefore, be it Resolved, That the Senate designates April 6 of each year as "National Tartan Day."
