Two queens were one too many in the fearfully dis-united kingdom of 16th century Britain. One, Elizabeth, had decided to return her country to the Protestantism her father Henry VIII had imposed on it. The other, Mary, favored the Catholicism that had reigned before Henry and still prevailed in most of the rest of Europe — including France, where she’d lived since childhood, safe from England’s wrenching back-and-forth religious wars, which left thousands dead with each shift of the political/religious winds.

Rampant beheadings, massacres and purges in the name of seemingly minor doctrinal differences, terrorism… if all this sounds familiar, it’s because humans are depressingly slow to change our ways. Playwright Peter Oswald understands these parallels, and his adaptation of the great 19th century German playwright Friedrich Schiller’s fictionalized version of the battle between the dueling queens crackles with contemporary vitality, which director Elizabeth Huffman channels into the most powerful theater production I’ve seen this year: Cygnet Productions and Northwest Classical Theatre’s Mary Stuart.
