During the 1990's the Chechens, the Sikhs, and the Tibetans have all protested their lack of independent homelands.
Explanation:
The 1990's was a period that East Asia witnessed to be the period of internal outrages from the members of different communities for the demand of separate homelands with an identity not associated with the lands they are originally a part of.
Tibet, originally used to be a separate nation, which was claimed by China to be its own part and later confiscated. Chechens demanded a separate country for themselves with the name Chechnya.
Sikhs demanded to get separated from India and form a country named Khalistan.
