In 1900, Romania was a young kingdom (since 1881). In comparison with today's map, it contained most of Moldova, but the Austro-Hungarian Empire owned Transylvania, which now forms its northwest section. It acquired additional territory, including Transylvania, during the Balkan Wars and World War I. World War II caused a net loss of territory, establishing the present-day boundaries.

Postal codes: 
Romania uses six-digit postal codes (Coduri postale). The first two digits identify the county.
Further subdivisions:
The third character (first digit) in a county's NUTS code represents the macroregion to which it belongs; the macroregions are simply called one, two, three, and four. The first four characters of the NUTS code represent a region. This table lists the level-4 NUTS codes and their regions.

Other names of subdivisions: 
According to Wikipedia (source [4]), the Romanian Academy considers the letters ș and ț to be correct for writing Romanian, and not ş and ţ. The difference is whether the diacritical marks below the s and t are commas (correct) or cedillas (wrong). Apparently a lot of people are using cedillas.
Where the county name is the same as its capital, the German name of the capital (dating back to the Austro-Hungarian Empire) is given.
