We've recently learned the difference between the Canadian and American perspectives on the War of 1812. But we both call it The War of 1812. Since each war has two sides vehemently opposed, certainly there exists semantic warfare in discourse about the wars themselves.

The best example that comes to mind relates to the American Civil War. Many (or most) American educators call this, simply, the Civil War. But while visiting Atlanta, Georgia, I was shocked to find the teachers and textbooks refer to this as The War of Northern Aggression.

What we call a battle, others may call a massacre. Any other interesting examples of semantic warfare in the naming of wars or events?
