Administratively, Mani is now divided between the prefectures of Laconia (Kato Mani, Mesa Mani) and Messenia (Exo Mani), in the periphery of Peloponnesos, but in ancient times it lay entirely within Laconia, the district dominated by Sparta. The Messenian Mani (also called "aposkiaderi", a local expression meaning "shady") receives somewhat more rainfall than the Laconian (called "prosiliaki", a local expression meaning "sunny"), and is consequently more productive in agriculture. Maniots from what is now Messenian Mani have surnames that uniformly end in "-éas", whereas Maniots from what is now Laconian Mani have surnames that end in "-ákos"; additionally there is the "-óggonas" ending, a corruption of "éggonos", "grandson".
