Historically, the Wa have inhabited the Wa States, a territory that they have claimed as their ancestral land since time immemorial. It is a rugged mountainous area located between the Mekong and the Salween River, with the Nam Hka flowing across it. The Wa traditionally practiced subsistence agriculture by cultivating rice, peas, beans, poppies and walnuts. They bred water buffaloes, which they used mainly for sacrificial purposes. Generally, the traditional customs of the Wa, as well as their lifestyle, are very similar to those of the Naga people further to the Northwest.
