The NY Times made a foray into European history last week, and, not surprisingly, now requires the following correction:

The article also referred incorrectly to Maria Theresa, an 18th century Austrian monarch. She was the archduchess of Austria, who ruled from 1740 to 1780. She was not an empress of the Austro-Hungarian Empire, which was not formed until the union of Austria and Hungary in 1867.

OK, maybe it required not this correction, but a different one. The Austro-Hungarian Empire was formed in 1867, by the division of Hungary and Austria. What had been the Austrian Empire became the Austro-Hungarian Empire, with the Emperor of Austria now also being King of Hungary. Hungary got its own parliament and executive structure, but the Times makes it sound more like a merger than a spinoff.
