Flag of the Prussian Commonwealth, Anglo-Iberian timeline.
This flag has been used since 1904, after the new borders of Prussia were consolidated. Compared with the previous flag, the two golden stripes were added to represent victory and new wealth, and the wings of the eagle were shown spread rather than folded, reminiscent of the Prussian War Flag used throughout the Great War, again representing victory and showing Prussia's prowess and dominance in north-central Europe as a military power.
Prussia lost much of it's global territories during the Great War, including - most devestatingly - most of Japan, which had been conquered earlier in the previous century. Even so, Prussia is still a dominant and major European power, and the Commonwealth includes territories in East Africa, Indochina, and the city-states of Aden in Arabia and Wilhelmburg in Australia.
The flag of the Kingdom of the American States from this map [link] called "The Grand Blue" in contrast to the American warflag, which is called "The Glorious Blue", or sometimes just "The Blue". The blue comes from the colour of American military uniforms, the sixteen stars represent the sixteen founding states (the thirteen from our world, plus Vermont, East Florida and West Florida), and the stripes represent war in red and peace in white (as the American States gained their independence through war there are more red stripes than white, in order to remind people of the nation's origins, and the occasional necessity of war).
4 Different proposals for an alternate Alaska that I had designed. The first one I chose to put into the flagdesign challenge that was posted on the Alternatehistory,com forums by JJXDB:
Design the flag for an Alaska that was never purchased by the USA, with its capital at Novoarkhangelsk (OTL Sitka). Your entry may pertain to one of the following options:
Option 1: A fully integrated Russian majority Krai of the Russian Federation, assuming the butterfly effects of this are minimal and history continues as it was OTL during the 20th Century.
Option 2: A Russian majority independent Alaska, who won independence after the 1917 Revolution with the backing of both the British Empire and the USA. This Alaska may be a Republic or Kingdom, but is hostile to communism
Option 3: An Aleut majority independent Alaska, who won independence after the British Empire intervened on their behalf. Again, this Alaska may be a Republic or Kingdom, gaining independence during the October Revolution and is hostile to communism
Option 4: An Aleut and Canadian dominated region absorbed into Canada, with the decision by the Russian Government that selling Alaska to the British would pose less of a threat selling to the rising star of America. This happens in the run up to WWI.
In this timeline America and France stand as the two most powerful nations on Earth, a fact that has remained as such since the World War (1919), and periodically since the Great American War (OTL War of 1812).
Germany has never been united, however with the formation of the Council of Germania, there is finally hope to end the centuries of warfare between the Germanic states of Prussia and Rhineland. Austria has recently joined the council as well, under the leadership of President and United Germania icon Alois Hitler.
In the Caucasus National Syndicalist leader Ioseb Stalin's reign is nearing its end, as the Man of Steel nears death's door. Many fear civil war will break out upon his end.
In America it is a time of National Pride not seen since the turn of the century. The Chaotic Years have come to an end and with the inauguration of President Rose Wilder Lane, the country has signaled that it is time for a change from the policies of the Roosevelt (Elanor) years.
In Asia, China has entered a renaissance of economic and cultural development. The two century alliance with the United States seems to have finally brought the country into the developed world, and with the decline of Japan and Russia, China stands as the soul power in Asia.
Flags of Germany in an alternate timeline where Frankfurt Parliament succeeds and Grossdeutschland Federation is formed.
The new state chooses to use the Jenaer Students League's flag (which was the first flag to use german liberal colours) as its national flag and coat of arms (Gules, a fess Sable, an oak branch Or). The eagle stays two-headed ofcourse, as a reference to the HRE, or the dualism Austria-Prussia, catholic-protestant, etc.
The text in German says (thanks Sapiento) that the first row of naval flags is used in inner waters, while the second row is used in open sea. The three flags in the last row are the flags of the President of the Republic, the President of Bundestag and the Chancellor. (I don't have idea how Grossdeutschland could evolve into a federal Republic, but well...)
