So basically, Alandia was created after breaking apart from the earlier Druznian Confederation. The Hammer+Sickle represents the workforce, the badge represents the defense of the country, the rifle represents the revolution, and the plants represent "peace" (sure). The Red represents the lives lost from the revolution, the yellow represents the sun shining on the nation.

The North Druznian Socialist Republic was created after a revolution caused by the unfair work conditions and autocracy assassinated the Tsar, Tsar Druznia, King of the Druz. Red represents bloodshed, blue represents freedom, yellow represents wealth, the badge represents glory, the hammer+sickle represents the workforce, and legend has it that the Druznian explorers saw a bear fighting and scaring off a pack of wolves.

So that's the background of the flags.
