I recently visited my sister’s Presbyterian Church, and they, as part of their year-long recognition of the 500th anniversary of the Reformation, will be celebrating the Kirkin’ o’ the Tartan this month. Not knowing what that was, I did some Googling and learned a thing or two . . . or three or four.

First, according to none other than the Scottish Tartans Authority, the Kirkin’ o’ the Tartan was begun (at least in the US) by the Reverend Peter Marshall. Born in Coatbridge, Scotland, in 1902, Marshall came to the States at the age of 24 and eventually became pastor of the New York Avenue Presbyterian Church and chaplain of the US Senate. While at New York Avenue, he held a kirkin’ service as a way to raise money for World War II.

You might be wondering what it means to kirk a tartan (I know I was). Well, kirk is Scottish for church, and tartan was originally a word for a woolen fabric, and then it became the name for the plaids worn by Scottish Highlanders, with each clan having its own distinct colors and pattern. So to kirk the tartan means to wear your kilts and other Scottish-plaid garments to church.

Since its creation, tartan (plaid) has certainly gotten around and made its mark on the world. In fact, as Elizabeth Wayland Barber writes in The Mummies of Ürümchi, the oldest existing piece of tartan fabric was found in the tomb of a Celtic man (known as Cherchen Man) from around 1,000 BC, unearthed in, of all places, northwest China. And since then, it’s put down roots all over.

In the early 1600s, the British East India Company established a trading post, including Fort St. George, in the fishing village Madraspatnam (later Madras, and now Chennai). They chose the location, in part, because of the cotton cloth made there, and developed it into a textile hub. About 100 years later, madras came to the American colonies when the former governor of Fort St. George, Elihu Yale, made a donation, including madras cotton, to the Collegiate School of Connecticut. In recognition of his gift, the school changed its name to Yale College (today’s Yale University). Move ahead another 100 years or so, and the tartan pattern—handed down from the Scots—was woven into Madras cloth and became a hit, so much so that madras is now virtually synonymous with brightly colored plaids.

(There are a lot of sources for the history of madras, but I chose the Gentleman’s Gazette, because not only can they tell us how madras came to the Ivy League, they can also tell us how to wear madras shirts, shorts, jackets, ties, and belts to sport that Ivy League style.)

The British and French brought madras fabric to the Caribbean in the 1600s, and according to Carol Tulloch, in Defining Dress: Dress as Object, Meaning, and Identity, the madras “handkerchief” fabric became “a currency of slavery”—made in India, sold to traders in London, and then “used to barter for slaves in West Africa and to clothe slaves in the West Indies.” It’s unclear to me exactly when the madras cloth flowing into the Caribbean took on its characteristic plaid, but tartan is now part of the national dress of several islands, such as the quadrille of Jamaica and the karabela of Haiti.

Some say that the use of madras in the slave trade is what brought it to East Africa, where it has become a major element in the traditional dress of the Maasai, in the form of the shuka. Others claim the origin of the “African blanket” is from Scottish troops stationed there, or it was introduced by Scottish missionaries. An article in The Star of Kenya includes the tale of tartan coming to East Africa by way of the British, stating that during a visit by Queen Victoria, tartan fabric was used for table coverings and the Maasai were told to clothe themselves with the tablecloths so as not to offend the queen with their nudity. This seems rather apocryphal to me, especially since before wearing the modern cloth shuka, the Maasai wore a version made from animal hides, which would seem to have covered their nakedness just fine.

In South Africa, not only do traditional dancers from the Pedi people group wear red plaid, but it’s actually in the form of a kilt. In another somewhat fanciful, but popular, story, as recounted in South Africa’s Mail & Guardian, it is said that when British troops came to the area in 1878, they were led by kilt-wearing soldiers. The Pedi, thinking they were fighting against women, refused to shoot, until it was too late and the battle was lost. (So maybe the Pedi donned the kilts as a future battle tactic?) But others say the kilts were adopted after the Pedi fought by the side of the Scots during World War II.

Of course, I didn’t need to do any research to know that donning plaids is an essential part of the traditional dress of many tribes. Take, for instance, preppies, lumberjacks, and hipsters. But I certainly hadn’t put the pieces together for tartan’s reach around the globe and beyond.

Beyond? you ask. Lunar module pilot Alan Bean took care of that in 1969 when he carried a swatch of Clan MacBean Tartan to the moon and back during Apollo 12. A few years ago Bean gave a piece of that cloth to the Scottish Tartans Authority for safekeeping.

Now that’s getting around, in style.
