"Galicia and Lodomeria was not officially assigned to Hungary, and after the Ausgleich of 1867, it found itself in Cisleithania, or the Austrian-administered part of Austria-Hungary. The full official name of the new Austrian province was Kingdom of Galicia and Lodomeria with the Duchies of Auschwitz and Zator. After the incorporation of the Free City of Kraków in 1846, it was extended to Kingdom of Galicia and Lodomeria, and the Grand Duchy of Kraków with the Duchies of Auschwitz and Zator (German: Königreich Galizien und Lodomerien mit dem Großherzogtum Krakau und den Herzogtümern Auschwitz und Zator). Each of those entities was formally separate; they were listed as such in the Austrian emperor's titles, each had its distinct coat-of-arms and flag. For administrative purposes, however, they formed a single province." Wikis below
Contrary to the American habit of thinking that borders, flags and passports a nation do make, modern Ukraine is a new state largely created by the USSR.
Western Ukrainians tend to be descendants of the people of the Austrian province of Galicia.
They are usually oriented toward the West, are either Roman Catholic or members of uniate Catholic churches and speak Ukrainian as their mother tongue. People in eastern Ukraine are often oriented toward Russia, are Orthodox in religion and native Russian speakers.
In WW2 the people in former Galicia were often enthusiastic collaborators with the Germans in the hope of regaing a sovereign identity. In the course of that collaboration many committed mass murder against the usual victims of the Nazis. A great many of the real fighters in the present revolution are members of nationalist groups who look to the WW2 example for inspiration.
It increasingly seems possible to me that Russia will intervene post Sochi on behalf of Yanucovich who they will say is the legitimate president of Ukraine. He is now in Kharkiv (Kharkov). This is in NE Ukraine. That is probably an indicator of Russian intention unless something dissuades them. pl
