They represented part of the Colonial Revival, an aesthetic movement which prized association to America's earliest days, and which lingers yet today in the worlds of architecture and antiques. The obsession with the story of American independence, while it perhaps never faded completely from American memory, seems to have been inflamed anew around the middle of the nineteenth century.
First, the last of the Revolutionary generation died out. George Robert Twelve Hewes, a young shoemaker in the 1770s, became a celebrity in the late 1830s upon the publication of two accounts of his part in the revolution.[1] By the 1850s, the base of the Washington monument had been laid and preservationists campaigned to protect Mount Vernon.[2]

Following the American Civil War, reverence for Washington and Colonial America in general would reach a fever pitch as relics from the great man were put on display, first at the United States Patent Office (then one of the few fire-proof buildings in Washington, DC) and then at the Centennial Exposition in Philadelphia in 1876. Colonial fashions and souvenirs would be standard fare at the succession of expositions over the next decades, juxtaposed jarringly with the newest products of industrialization.[3]

The connection between architectural form and culture made Colonial style into a potent symbolic vocabulary by the turn of the 20th century. In an era of prescriptivism in the form of instructional manuals and early home decor catalogs, Colonial Revival houses and furnishings became not only symbols of good taste but also of good morals. The movement to preserve American homes, both in situ and reconstituted in art museums as period rooms was based on the idea that these surroundings could educate the masses on how to be American. Louisa May Alcott's family home was restored explicitly to indoctrinate the children of immigrants in the ways of American Culture.[5]
Colonial America has remained a potent symbol, its images evoked throughout the Cold War Era and as recently as the last decade, with the Tea Party Movement within the Republican Party.
What does not appear in a search for "colonial" is another relevant meaning of "colonial America" in 1918: America as colonizer rather than colonized. In the wake of the Spanish American War nearly two decades before, the United States's imperial power stretched across the globe, adding Guam, Puerto Rico, and the Philippines to Hawaii as territories under its control. In the decade before WWI, the United States added territories such as American Samoa and the U.S. Virgin Islands.
Eventually Hawaii would gain statehood and the Philippines would claim independence (that's a very long story) but many American territories remain, essentially, colonies. Guamanians serve in the American armed forces at almost double the rate of other American citizens but their only representative in congress is a non-voting delegate. [7]

What did it mean in 1918 for Americans to lift up styles from an era in which they felt oppressed as their country perpetrated oppression? It is worth noting that American imperialism has often had racist overtones. For instance, in 1918, the occupants in the territories mentioned above were not U.S. Citizens but U.S. Nationals and could thus neither vote or run for office.[8]

Today as in 1918, America's colonial pasts are entangled. What might we learn by considering the American colonies of the 18th and 20th centuries in the same space? For one thing, I suspect that the American citizens who live in our territories might have insights on taxation without representation.
