When he died, 17-year-old Anna Amalia could finally explore her musical talents. Her equally musical brother, the new King Friedrich II, taught her how to play the essential instruments of the day: harpsichord, flute and violin. Meanwhile, Friedrich also sought a royal husband for her. Anna Amalia had other ideas. She secretly wed one of Friedrich's soldiers, Baron Friedrich van der Trenck. Their liaison could not be kept secret when she fell pregnant. Infuriated her brother packed her off to Quedlinburg Abbey, a kind of 18th century home for unwed mothers and protestant convent. It is rumored that she was delivered of twins. (The Baron was imprisoned, but escaped. He was recaptured and imprisoned again. He spent much of his life as a spy, in and out of captivity before meeting his end on the guillotine in revolutionary France.)
Anna Amalia seems to have thrived at the abbey, where she was free to pursue her musical interests, and even began writing her own compositions. Few of her works have survived, partly because she destroyed them herself, in fits of perfectionism. More importantly, she collected works by contemporary German composers, including C.P.E. Bach, Handel, Telemann and J.S. Bach. Her extensive collection is credited with helping revive the legacy of Johann Sebastian Bach. More than 600 volumes from her collection are kept today at the State Library in Berlin.
Anna Amalia assumed a lot of authority when she became the Princess-Abbess of Quedlinburg, a self-ruling estate that was part of the Holy Roman Empire, subject only to the Emperor.
