Private Lives of the Monarchs (8/7c, Smithsonian Channel): Private lives, what a quaint concept. In a departure from the current obsession with Harry and Meghan and little Archie, this five-part series takes a historical long view, revisiting some of Europe's more memorable monarchs and their intrigues behind closed palace doors. First up: Queen Victoria and her troubled relationship with her eldest son, Edward, whose well-documented debauchery takes host Tracy Borman (Chief Curator of the Royal Palaces) to Paris brothels and Edward's official residence of Marlborough House, where spouse-swapping was commonplace. How scandalous.

Gentleman Jack (10:05/9:05, HBO): The boisterously entertaining yet curiously modern period piece presents ahead-of-her-time Anne Lister (Suranne Jones) with an unwelcome reality check when her beloved, Ann Walker (Sophie Rundle), begins to cave from social and peer pressure and 19th-century values to cool their forbidden relationship. Naturally, our fierce Miss Lister won't give up without a fight, even when the battle is coming at her from all sides.
