Things don't end well for dictators and kings with gilded bathrooms and ballrooms: aaaz1a.jpg (click to show)

Nicolae Ceaușescu and his wife Elena were executed by firing squad.
King Louis XVI and his Queen Marie Antoinette were beheaded by guillotine.

Don't forget Nero, builder of the Golden House, who suicided to evade pursuit by the law after he'd been declared an enemy of the state.

Also Czar Nicholas of Russia and his entire family, all executed. An autocratic ruler with an opulent lifestyle.
