The village of Arden, is an art colony in New Castle County, Delaware, United States, founded in 1900 as a radical Georgist single-tax community by sculptor Frank Stephens and architect Will Price. The village occupies approximately 160 acres, with half kept as open land. According to the 2010 census, the population of the village is 439. In 1973, the entire village was listed on the National Register of Historic Places. Two neighboring villages of similar size were founded on Georgist principles, Ardentown, in 1922, and Ardencroft, in 1950. In 2003, they were also listed on the NRHP as the Ardens Historic District. Many Ardenites, as the villagers of Arden are called, consider themselves to be "close-knit, nature-loving, liberal, tolerant, free-spirited, artistic, intellectual, even ex-hippie". History Arden was founded in 1900 by sculptor Frank Stephens and architect Will Price, based on ideas such as Henry George's single-tax, William Morris’s Arts and Crafts principles, and Peter Kropotkin's theories of community. Philanthropist Joseph Fels funded the project. The single-tax movement, popular in the U.S. and other countries from the 1890s until the 1930s, is based on the belief that the best way to raise government money was to tax only the value of unimproved land and the public-created value, like roads, added to the land. The tax, based on a systematized assessment, would recover both the value of natural resources and public investment for the public, while not impeding labor and capital from profiting from their efforts. Followers of Henry George's philosophy of economics created Arden as an experiment in the single-tax idea after a failed attempt to implement Georgism in the entire state of Delaware in the late 19th century. Englishman William Morris rebelled against modern cities and industry. He advocated a return to craft production, good design, and village life. Kropotkin was primarily an anarcho-communist whose ideas regarding social and community living were used by the founders of Arden to advance Morris' ideas for the return to village life. Land in Arden cannot be sold; instead it has a renewable 99-year lease. The leasehold interest in the land has a market value and can be sold. People are free to improve it as they choose, but the land-lease fee will not increase because of improvements. Arden is not exempt from New Castle County land taxes, but the buildings within the village are taxed separately for county and school district revenue, while
