Usaianism

Usaianism is a political and moral philosophy based on adherence to the values set forth in the United States' Declaration of Independence and its Constitution. It was first promulgated by Sarah A. Hoyt in her Darkship Thieves series. Many characters in my Timelines series and its spinoffs, Timelines Universe and the BBESP series (particularly the latter), are Usaians of one stripe or another; the Milky Way Star Empire was, indeed, founded on Usaian principles.
