The Lao kingdom of Lan Xang Hom Khao (Lao:ລ້ານຊ້າງຂາວຂາວLanxanghômkhao/laːn˥˧ saːŋ˥˧ hom˧ khaːw˥/, from ລ້ານ "million" + ຊ້າງ "elephants" + "[under] the white parasol"; Thai:ล้านช้างร่มขาว, rtgs:Lan Chang Rom Khao; SanskritSrī Sattanāganahuta; Burmese:လင်ဇင်း; Vietnamese:Vạn Tượng) existed as a unified kingdom from 1354-1707.
For three and a half centuries, Lan Xang was one of the largest kingdoms in Southeast Asia. The "million elephants under the white parasol" of the kingdom's name alludes to the power of the kingship and formidable war machine of the early kingdom. The kingdom is the precursor for the country of Laos and the basis for the national historic and cultural identity.
