Many of the 19th century descriptions of the Sarakatsani do not differentiate them from the other great shepherd people of the Balkans, the Vlachs, a Romance-speaking population. In many instances the Sarakatsani were identified as "Vlachs". Aravantinos discusses how another group, the Arvanitovlachs, were erroneously called "Sarakatsani", although the latter were clearly of Greek origin, increasing the differences between the two groups and stating that the Arvanitovlachs were actually yet another group, the "Garagounides" or "Korakounides". The Sarakatsani have also been referred to as "Roumeliotes" or "Moraites", names based on where they lived. Otto, the first king of modern Greece, was well-known to be a great admirer of the Sarakatsani, and is said to have fathered an illegitimate child early in his reign with a woman from a Sarakatsani clan named Tangas.
