Bavaria was a very agricultural heavy state, that made a few things right in the last few hounded years. Bavaria has like every over German state a long and rich independent history. Only Bavarian nationalists dream of an independent Bavaria. Hitler joined the NSDAP in Munich and it was one of it's early strongholds. Most German cities were destroyed in WWII. Germany did not "pay" reparations, because they still had a lot of open dept from WWI. They paid with land, factories, infrastructure and forced labor. What the guide meant was probably the so-called "soli". It is a special tax that was levied from former Westgerman states to support former GDR states, which did not develop as much under the socialist rule. That tax was and is controversial and was changed to nowadays only applie to richer people.

Bavaria was always a big state in german, that tries to play a special role. Especially their main party the CSU participated in German politics, while enforcing predominantly Bavarian Interests. These methodes were obviously anti democratic but only borderline illegal and forced the government to restructure the parliament.

So yea. I grew up in Bavaria and I get why most Germans are quite annoyed with bavarians.

It is the German Texas.
