Pleased to note that the state of Mississippi might be on the verge of reviving the Magnolia flag (scroll down to 4), its flag during the Civil War and unofficial flag until 1894.

From Business Insider:
Mississippi could become the first US state to have 2 official flags because of a dispute over the Confederacy
Brennan Weiss, Jan. 13, 2018
A Mississippi lawmaker is proposing a solution that he hopes will finally bring an end to one of the state’s most divisive issues, The Wall Street Journal reported.
Earlier this month, Republican Rep. Greg Snowden filed a bill that would allow two flag designs to officially represent the state. If the measure passes, Mississippi would be the only US state with two flags.
Mississippi’s current flag, which features the symbol for the Confederacy, would be left untouched. A proposed second flag would bring back an old design used on the state’s official flag from 1861 until the end of the Civil War in 1865.
That design features a magnolia tree in the center of the flag and a white star against a blue background in the top-left corner, replacing the controversial Confederate emblem currently in its place.
“We feel that it is most appropriate to adopt the historical Magnolia Flag as an additional design of the official state flag that may be flown with equal status and dignity to represent our state as we are beginning our third century as a member of the United States,” the bill says.
Snowden argued that his solution will appease both sides of the flag debate. While some Mississippians consider the current flag to be a historical tribute to their ancestors who fought and died in the Civil War, others believe it glorifies slavery and the systematic oppression of black people.
The two-flag proposal would allow people to choose which flag they want to represent them. Snowden’s bill says that both flags could be flown together or individually.
I think this is great. The Confederacy is indeed a part of “our heritage,” but it does not deserve to be memorialized so prominently, and at the expense of everything else that’s also part of our heritage. The Magnolia flag is historic, and a nice design, and as I said before, is even more appropriate to Mississippi than the current flag: eleven states were in the Confederacy, but there’s only one Magnolia State. But that Rep. Snowden’s proposal does not seek to completely displace the current flag is a nice compromise.
(As noted before on First Floor Tarpley, the country of Bolivia also recognizes two official flags: a traditional European-derived horizontal tricolor, and a square, checkered flag called the Wiphala, in honor of Bolivia’s native Andeans.)
