"Westphalia (/wɛstˈfeɪliə/; German: Westfalen [vɛstˈfaːlən]; Low German: Westfalen [vεs(t)´fɔːln]) is a region of northwestern Germany and one of the three historic parts of the state of ...
North Rhine-Westphalia. It has an area of 20,210 km2 (7,803 sq mi) and 7.9 million inhabitants.
The region is almost identical with the Province of Westphalia, which was a part of the Kingdom of Prussia from 1815 to 1918 and the Free State of Prussia from 1918 to 1946. In 1946, Westphalia merged with the Northern Rhineland, another former part of Prussia, to form the newly created state of North Rhine-Westphalia. In 1947, the state with its two historic parts was joined by a third one: Lippe, a former principality and free state." - (en.wikipedia.org 31.01.2020)
