Frederick II of Saxony-Gotha-Altenburg married Magdalena Augusta of Anhalt-Zerbst in 1696 in Gotha. Together, the couple had 18 children, including the seven sons, which are shown on the coin offered here: Frederick (III), William, John Augustus, Christian William, Louis Ernest, Maurice and John Adolf.
Frederick was a lavish ruler who spent vast sums of money on his court and his standing army. Magdalena Augusta had a rather simple mind: She refused to let her daughter be taught English, although she should marry the presumptive British heir to the throne, because: "[...] the Hanover family was over twenty years on the English throne. So people in England and especially at court would have to speak German as often and as good as English."
Nonetheless, the Duchess' letters to her husband (kept in the Gotha Library) testify to a harmonious and loving marriage.
