Veligosti, near ancient Megalopolis, appears to have fallen to the Frankish Crusaders without resistance . The name's origin is obscure. The 19th-century historian Karl Hopf thought that the Greek name derived from the French form Véligourt, in turn possibly a corruption of &lt;a href="Walincourt"&gt;Valaincourt/Walincourt&lt;/a&gt;, which Hopf proposed as the place of origin of the original baronial line of Mons. The Valaincourt family was indeed represented in the Fourth Crusade, but as the French medievalist Antoine Bon pointed out, there is nothing other than the similarity of the names to link them to the Frankish Morea. Bon himself considers the form "Veligosti" to be the original one—of ultimately Slavic origin—and the French name to have been derived from it.
