Ever noticed how many wines in South Africa have โ€œChateauโ€ as part of their name? Only one: Chateau Libertas. 

In 1935, the country signed an agreement with the French* that prevented the use of the term by any local producer from that point on. Why the exception for Chateau Libertas? It was established in 1932, before the deal was inked, so it escaped the prohibition.
