(Disclaimer: I do not support racism in any form. This is merely a hypothetically question. Be respectful, and don't say any racial slurs or ideas.)
A popular misconception in the modern day is that this flag was the national flag used by the Confederate States of America:
This was not the flag of the CSA. It was elongated version of the Confederate Battle Flag. also know today as the Rebel Flag. These flags were national flags of the Confederacy, such as the Stars and Bars, Stainless Banner, and the The Blood-Stained Flag. However, the Battle Flag remained popular.
So in a hypothetical Confederate Victory, where the CSA won around mid-1862 to early 1863, where the CSA gotten recognition from the British and French Governments. In a post-war scenario, would've the CSA changed their flag to the Battle Flag?
