Имерина
According to popular legend, King Andrianjaka (1610–1630) declared twelve hills in Imerina (the central region of the Highlands of Madagascar) to be sacred due to their historical, political or spiritual significance to the Merina people. King Andrianampoinimerina (1787–1810) designated twelve hills in his turn, including several of those first identified by Andrianjaka. Most of these hills served as locations of the capitals of rival kingdoms conquered by Andrianampoinimerina and united under his rule, and many are also the seat of power of historic kings and queens of the Merina dynasty.
