Here's a map of the Kingdom of Serbs, Croats and Slovenes - which existed from 1918 to 1941.
Below is a map of post WWII Yugoslavia after Tito's pen ran out of control... Lucky Croats.
From 1929, the Kingdom was subdivided into nine new provinces called banovinas or banates. Their borders were intentionally drawn so that they would not correspond either to boundaries between ethnic groups, or to pre-World War I imperial borders. They were named after various geographic features, mostly rivers. Slight changes to their borders were made in 1931 with the new Yugoslav Constitution. The banovinas were as follows: Danube Banovina (Dunavska banovina), with its capital in Novi Sad Drava Banovina (Dravska banovina), with its capital in Ljubljana Drina Banovina (Drinska banovina), with its capital in Sarajevo Littoral Banovina (Primorska banovina), with its capital in Split Morava Banovina (Moravska banovina), with its capital in Ni Sava Banovina (Savska banovina), with its capital in Zagreb Vardar Banovina (Vardarska banovina), with its capital in Skopje Vrbas Banovina (Vrbaska banovina), with its capital in Banja Luka Zeta Banovina (Zetska banovina), with its capital in Cetinje The City of Belgrade, together with Zemun and Pančevo was also an administrative unit independent of the banovinas. Banovina of Croatia: 1939-1941 As an accommodation to Yugoslav Croats in the Cvetković-Maček Agreement, the Banovina of Croatia (Banovina Hrvatska) was formed in 1939 from a merger of the Maritime and Sava Banovinas, with some additional territory from the Drina, Dunav, Vrbas and Zeta Banovinas. Like Sava, its capital was Zagreb.
Banovina of Croatia: 1939-1941
As an accommodation to Yugoslav Croats in the Cvetković-Maček Agreement, the Banovina of Croatia (Banovina Hrvatska) was formed in 1939 from a merger of the Maritime and Sava Banovinas, with some additional territory from the Drina, Dunav, Vrbas and Zeta Banovinas. Like Sava, its capital was Zagreb.
In 1941, the World War II Axis Powers occupied the Banovina of Croatia and the province was abolished. Some of the coastal areas from Split to Zadar and near the Gulf of Kotor were annexed by Fascist Italy but the remainder became a part of the Independent State of Croatia. Following World War II, the region was divided between new states of Croatia, Bosnia and Herzegovina and Serbia (autonomous Vojvodina province) within a federal Socialist Yugoslavia.
The banovinas of Yugoslavia, established in 1929, deliberately avoided following ethnic or religious boundaries which resulted in the country's ethnic Croats, like other ethnic groups, being divided among several banovinas. Following a struggle within the unitary Kingdom of Yugoslavia, Croat leaders won autonomy for a new ethnic-based banovina with the Cvetković-Maček Agreement.
Tito (a Croat... some insiders say a native Russian who poached the real Tito's identity during the Spanish civil war... but that's another story)
Tito had a slight but distinguishable Russian accent which he never managed to get rid of. Speculation has it that the real Tito died during the Spanish Civil War and was replaced by an NKVD agent - the new Tito. These theories were popular in Yugoslavia from 1945 up until the break with Stalin in 1948. Evidence cited pointed to Yugoslav policy which seemed to be dictated from Moscow.
Here's an extract from a CIA report from 1945:
In foreign affairs, as in internal affairs, Russia is the lodestone governing Tito's policies. In every international issue, whether it is the direct concern of Yugoslavia or not, Tito and his press assiduously follow Moscow's lead. In fact, Tito and his followers exhibit a servility toward the Kremlin which contrasts strangely with their otherwise dynamic individuality. It is enough for Moscow to express a view and the Belgrade press reprints it in toto, adding a few biting words of its own. Under these circumstances it is no small wonder that in Belgrade one finds no evidence of a corps of Russian agents directing the activities of individual ministries or agencies. Should the necessity arise for specific guidance, no doubt a brief message from Stalin to Tito would suffice.
Following the break with Stalin in 1948, Tito embarked on a policy of rapprochement with NATO which culminated in discussions about whether to admit Yugoslavia into the organization or not. Milutinovic maintained that Tito was ready to enter the organization but that the Americans were weary of accepting a potential Trojan horse into their back yard.
That said... I have no idea where the truth really stands.
The theory that Tito was in fact not Croatian is also put forward by these insiders. They mention, for example, that nobody in Kumrovac - Tito's alleged place of birth - actually recognised or knew Tito. Other circumstantial evidence is that after WWII, President Tito never met his mother, who was still alive.
Migeru dug up what the preceding situations were back to your first map (1929, 1939 administrative changes). But your choice of the 1929 situation is arbitrary, we can go further back. In 1921-1929, there were no large regional units that could even be mistaken for national units like the 1929 version, just small oblasts. Before that, there was more or less a continuity of the territorial units of Austria-Hungary. Within that, Croatia was more or less as today along the Dalmatian Coast (while it extended further down to Belgrade along the Danube but missed Istria). *Lunatic*, n. One whose delusions are out of fashion.
You could go back even further and show that Serbia was once established on the territory of Bosnia and had control of 50% of the Dalmatian coast.
The point is that the national borders that we see today emerging from ex-Yugoslavia are those that Tito drew up in 1943.
(I note that my own view is that Tito shouldn't have re-instated national borders, and should have taken over the pre-1939 centralisation policy while stripping it of the Serb-first element, and adding more cultural autonomy.) *Lunatic*, n. One whose delusions are out of fashion.
The map of the Banovinas that I posted represents the boundaries set up in 1929 which were effective up until 1939.
The borders established by the Cvetković-Maček Agreement were only effective as of 1939 for 2 years, up until the creation of Nazi puppet state NDH. NDH occupied what is today's Croatian plus Bosnian territories. IMHO, there is no basis to say that these frontiers (as opposed to others) should be used to compare the situations pre and post WWII.
In fact, all of these borders were of administrative nature and have no relation with the ethnic composition of the territories. If national self-determination is the goal, then maps based on ethnic composition of the population are most appropriate.
Which Serbia and era? *Lunatic*, n. One whose delusions are out of fashion.
There is no mention of Tito being in the Spanish Civil War in the English Wikipedia article...
In 1934 the Zagreb Provincial Committee sent Tito to Vienna where the Central Committee of the Communist Party of Yugoslavia had sought refuge. He was appointed to the Committee and started to appoint allies to him, among them Edvard Kardelj, Milovan Djilas, Aleksander Rankovic, and Boris Kidric. In 1935, Tito traveled to the Soviet Union, working for a year in the Balkan section of Comintern. He was a member of the Soviet Communist Party and the Soviet secret police (NKVD). In 1936, the Comintern sent "Comrade Walter" (i.e. Tito) back to Yugoslavia to purge the Communist Party there. In 1937, Stalin had the Secretary-General of the CPY, Milan Gorkić, murdered in Moscow. Subsequently Tito was appointed Secretary-General of the still-outlawed CPY.
Tito's personal files, which were considered Russian state secret for over 70 years and held in Stalin's archives (currently the Presidential Archives of the Kremlin) have recently been made public. According to these documents, which detail a large part of the Komintern's activities, Tito is said to have participated in the Spanish Civil War. This is something that Tito consistently omitted from his numerous biographies. The mistery was all the greater considering that all the other veterans of the Spanish Civil War proudly promoted theur roles in this endeavour, considered to be a great achievement.
Tito, on the other hand, consistently avoided the subject like the plague. He had only two public phrases to share with the world about the Spanish Civil War. Namely, in a biography for Life Magazine - 5 May 1959, he is reported as saying : "Although there are rumours to the contrary, I am not a veteran of the Spanish Civil War, even though I would have liked to be. I was in Spain only on one occasion, briefly, when I spent a day in Madrid". A year later, Tito instructed the author of his biography, Vladimir Dedijer, who had helped him prepare the article for Life Magazine, to make no mention whatsoever of these two sentences in a book published in Yugoslavia in 1953.
Indeed, all journalists were prohibited from engaging in public speculations about his role in the Spanish Civil War. The Moscow Presidential Archives, which are off limites to foreigners, recently transferred a number of documents concerning Tito to the Rissian National Archive of Socio-Political History. Tito's political heritage can as of now be found in a single place, accessible to both Russian and foreign researchers.
We can at last come to grips with one of Tito's most closely kept secrets. A reporter from « Novosti » informs us that his research has uncovered a document which clearly confirms that "... Josip Broz Tito participated in the Spanish Civil War from 1936 to 1939.". And so we uncover another of the Grate Magician's secrets, which has been a source of conjecture for many decades throughout the world and in Yugoslavia.
Speculation was increasingly public near the end of Tito's life when in a book about him entitled "Great Achievements" was published containing a letter he wrote in late 1937 to Moscow in which he suggested that Moscow accept a Croat Communist - Ivan Krajačića, for "specialised political instruction" claiming that Krajačića had proven his valour during the Spanish Civil War. Tito made another recommendation on the same grounds for Slovenian Communist Josip Kopinič.
Another document was found in which Tito's closest associate, Edvard Kardelj claimed that he remembers how the Leader of the Yugoslav Communists spoke well of the Slovenian Communist Franc Rozman, whom he remembered as a good man from the Spanish Civil War.
Tito's participation in the Spanish Civil War was also confirmed by the Chief of the Spanish Communists Dolores Ibaruri. Nevertheless, Toto consistently negated his presence in Spain.
Now that the truth has finally been uncovered in the Russian archives, the natural question that arises is why Tito so vehemently negated his participation in a War that all others openly bragged about. The most logical answer is that Tito wanted to cover up his real role in this war, which wasn't one of combat but of "special actions" which would have polluted his otherwise rich biography.
Marshal Tito, who by his real Jewish name is called Josif Walter Weiss, was born in Poland. He was agent of the Soviet secret service in Kabul, Teheran and Ankara up to 1935. The true Brozovich Tito, in origin a Croat, died during the Spanish civil war in Barcelona.

On the outbreak of the Spanish Civil War the Comintern established the Dimitrov Battalion. Named after Georgi Dimitrov the battalion comprised of Greeks and people from the Balkans. Tito eventually became one of the battalion's senior commanders.
There's a photo of (what the author says is) Tito in the Brigades.
