Here's a short story:

Baden-Württemberg is a state in Germany located in the southwest, east of the Upper Rhine. It is Germany’s third largest state in terms of size and population, with an area of and 10.8 million inhabitants. The state capital and largest city is Stuttgart. 

The sobriquet "Ländle" ("small land" or "dear land" in the local dialect) is sometimes used as a synonym for Baden-Württemberg. 

Baden-Württemberg is formed from the historical territories of Baden, Prussian Hohenzollern, and Württemberg, parts of Swabia. 

In 100 AD, the Roman Empire invaded and occupied Württemberg, constructing a limes (fortified boundary zone) along its northern borders. Over the course of the third century AD, the Alemanni forced the Romans to retreat beyond the Rhine and Danube rivers. In 496 AD the Alemanni themselves succumbed to a Frankish invasion led by Clovis I. 

The Holy Roman Empire was later established. The majority of people in this region continued to be Roman Catholics, even after the Protestant Reformation influenced populations in northern Germany. In the late 19th and early 20th century, numerous people emigrated from here to the United States for economic opportunity. 

After World War II, Allied forces established three federal states in the territory of modern-day Baden-Württemberg: Württemberg-Hohenzollern, Baden, and Württemberg-Baden. Baden and Württemberg-Baden were occupied by France and the United States, respectively. In 1949, each state became a founding member of the Federal Republic of Germany, with Article 118 of the German constitution providing an accession procedure. On 16 December 1951, Württemberg-Baden, Württemberg-Hohenzollern and Baden voted in favor of a joint merger via referendum. Baden-Württemberg officially became a state in Germany on 25 April 1952.
