Biography

Between Bach's employer and Anna Amalia's regency stands a duke who wanted to be Louis XIV and could not afford it. Ernst August spent nineteen years quarrelling with the uncle he was co-regent with, ruled alone from 1728, hunted more than he governed, and built the summer palace at Belvedere, which is still there to visit.

Nineteen years of co-regency, 1709–1728

Born in Weimar on 19 April 1688, he became co-regent in 1709 alongside his uncle Wilhelm Ernst — an arrangement neither wanted. The conflict escalated until 1723, when imperial intervention was required to restore peace between them; the biographical article on his uncle calls the co-regency a lasting unhealthy condition. Only when Wilhelm Ernst died in 1728 did Ernst August rule alone.

A copy of Louis XIV

The nineteenth-century biography is blunt about the type: he was one of those German princes who enjoyed being a copy of Louis XIV, and yet had original qualities of his own. He took an interest in administration and justice, and indulged, increasingly, his inclination for splendour and magnificence. The duchy's passion for hunting cost time and money it did not have.

What he built, 1741–1748

The pleasure palace at Belvedere is his; it appears on a work he published anonymously in 1742 under his cipher, with a view of it. In 1741 he acquired Saxe-Eisenach and spent much of his time there afterwards. He died at Eisenach on 19 January 1748, and the court he left behind was the one Anna Amalia would take over as regent ten years later.

Historical Context

The second half of the Baroque court: hunting, building, and a duchy living beyond its means.

The century and a half between two castle fires is the Weimar nobody puts on a poster, and it is the one that made the town musical. It opens with a burnt-out castle in 1618 and closes with another one in 1774 — and in between, in a chapel that no longer exists, Johann Sebastian Bach wrote most of his organ music.
