Louis invoked her hereditary claim to the Palatinate as pretext to launch the Nine Years´ War in 1688. Her vast, frank correspondence provides a detailed account of the personalities and activities at the court of her brother-in-law, Louis XIV, for half a century, from the date of her marriage in 1672." - (en.wikipedia.org 14.07.2020)
