“The Zulu are the largest South African ethnic group, with an estimated 10–11 million people living mainly in the province of KwaZulu-Natal. Small numbers also live in Zimbabwe, Zambia, and Mozambique. Their language, Zulu, is a Bantu language; more specifically, part of the Nguni subgroup. The Zulu Kingdom played a major role in South African history during the 19th and 20th centuries. Under apartheid, Zulu people were classed as third-class citizens and suffered from state-sanctioned discrimination. They remain today the most numerous ethnic group in South Africa, and now have equal rights along with all other citizens”. – Wikipedia.

For centuries, the sleepy valley nestled in the Indian Himalayas remained a hidden Buddhist enclave forbidden to outsiders. Enduring the harsh year-round conditions of the high mountain desert, the people of Spiti Valley lived by a simple communal code – share the Earth's bounty, be hospitable to neighbors, and eschew greed and temptation at all turns. That's all starting to change, for better or worse. (Photo by Thomas Cytrynowicz/AP Photo)
