I have both variants defaced. One with the tryzub defaced in the center, the other in the canton. Neither are official. I kept asking my friend in Ukraine for the classic grain and sky one. It is debated whether or not that was interpreted after-the-fact. But the presidential standard has the trident.
I don't think it is a State Flag variant like Austria et al. The red and black variant is interesting and I've seen it used, not in the best situations. It has nothing to do with anarcho-syndicalism. I think it's actually been used by slightly more right leaning groups.
Ukraine also has awesome flags for the military. This is literally my second day as a member. I'm not trying to espouse any beliefs, you will get it fast. But, flags are inherantly political by definition. As an aside, there was a new protest flag for the Russian flag without the red in the tricolour that almost mimicked the Belarusian protest flag. The Belarusian flag, the white-red-white flag with a white-blue-white flag.
The symbolism was because red always represents what? In this case, blood and war, not Communism. I thought it clever. These were Russians against the war in Ukraine.
Hi, I'm new and this is an old thread, but I know more than this about flags.
As to the history of the Trident, you can look it up. I'm against coat of arms and state seals being slapped on bedsheats but it is super cool, IMHO.
